[00:00:54] <jepler> alex_joni: http://emergent.unpy.net/files/01172617016/fb.c
[00:03:37] <alex_joni> what's __FILE__ ?
[00:03:52] <alex_joni> ahh.. name of the source
[00:04:11] <alex_joni> nasty
[00:05:28] <alex_joni> jepler: nice one
[00:06:35] <alex_joni> I see you took over the idea for printf :P
[00:06:54] <alex_joni> "%s\n\0%d\n"
[00:22:01] <jlmjvm> jepler: r u still here
[00:27:09] <a-l-p-h-a> if you were a cookie, would you want to be eaten, or saved for later?
[00:27:18] <a-l-p-h-a> or cleared from your cache?
[00:27:37] <Jymmmm> EAT ME!
[00:27:49] <Jymmmm> Cuz if ya save me, I'll just go stale on ya
[00:28:00] <a-l-p-h-a> heh
[00:29:00] <Jymmmm> a-l-p-h-a Did you ever get any of that machinable wax yet?
[00:29:08] <a-l-p-h-a> nah.
[00:29:14] <a-l-p-h-a> I haven't even turned on my mill in months.
[00:29:16] <jlmjvm> has anyone here ever used a usb jog_pad
[00:29:25] <a-l-p-h-a> jlmjvm, not I my friend.
[00:29:43] <Jymmmm> No, but I used a PS/2 NUMPAD as a jog pendant.
[00:29:54] <Jymmmm> s/used/use/
[00:31:27] <jlmjvm> ,i use a usb num pad myself,but have a usb shuttle express here and was trying to make it work
[00:31:43] <Jymmmm> http://ec3.images-amazon.com/images/P/B00005BAUP.01._AA280_SCLZZZZZZZ_.jpg
[00:32:26] <jlmjvm> http://www.contourdesign.com/shuttlepro/shuttlexpress.htm
[00:32:27] <Jymmmm> I'm not fond of USB for the most part. Especially for critical timing I/O stuff.
[00:32:56] <jlmjvm> these work great in mach3
[00:33:07] <jlmjvm> i put the web site up
[00:33:46] <Jymmmm> With the PS/@ KEYPAD, I can just daisychain if I want more than one, and no drivers are required.
[00:34:34] <Jymmmm> even works in DOS too =)
[00:34:54] <jlmjvm> thats what i do with my usb keypad,have a usb extension that i plug in when i need it
[00:35:28] <jlmjvm> didnt know the ps/2 would work in dos
[00:38:01] <jlmjvm> on the shuttle the outer ring is spring loaded and rotates 90 deg either way,the inner wheel has clicks
[00:39:19] <jlmjvm> its for people that want a wheel,this is the second one ive gotten for my mach3 customers
[02:25:28] <skunkworks> wife is leaving for Cancun tomorrow morning.. the loser. ;)

[03:18:11] <jmkasunich> * jmkasunich frowns at jepler
[03:18:24] <jmkasunich> 2007-02-28 03:03:18 build: emc2head : 12 hours since last complete build
[03:18:24] <jmkasunich> 2007-02-28 03:03:18 build: emc2head : start complete build
[03:18:38] <jmkasunich> you're supposed to commit stuff when I'm not home ;-)
[03:25:00] <ejholmgren> that sounds devious
[03:25:15] <jmkasunich> nah
[03:25:24] <jmkasunich> its because the compile farm brings my PC to its knees
[03:25:36] <jmkasunich> especially when doing full builds
[03:25:42] <ejholmgren> are they running as vm's >
[03:25:49] <jmkasunich> 3 of the 4 are VMs
[03:26:05] <ejholmgren> I can see how that would be annoying
[03:26:26] <jmkasunich> especially since I'm experimenting with FPGA place-and-route, which is very CPU intensive
[03:30:42] <jepler> hi jmk
[03:30:47] <jmkasunich> hi
[03:30:59] <jepler> alex_joni says I'm supposed to ask you how you like my C++. http://emergent.unpy.net/files/01172617016/fb.cc
[03:31:16] <jmkasunich> I saw that discussion
[03:31:21] <jmkasunich> I don't do C++
[03:31:25] <jmkasunich> it is evil
[03:31:54] <ejholmgren> mistrusting of objects are we?
[03:31:55] <jepler> I agree, more or less
[03:32:04] <jepler> but I had a great sense of satisfaction after writing that C++ program
[03:32:09] <jmkasunich> heh
[03:32:52] <jmkasunich> while I was reading that discussion (and pondering the perversness of the people who hang out here) I thought about how I (as a hardware guy) might take that test
[03:33:03] <jmkasunich> C would be my first choice, I know it better than any other language
[03:33:15] <jmkasunich> but vhdl might be fun
[03:33:23] <jmkasunich> (hard to print the results tho)
[03:34:02] <jepler> 2400 baud serial 7E1?
[03:34:03] <jmkasunich> could probably produce a 10 bit output - the number on 8, and two more bits to mark fizz and buzz
[03:34:16] <jepler> in ASCII
[03:34:33] <jmkasunich> the serial output would be for extra credit
[03:34:52] <jmkasunich> and rather insane
[03:35:52] <jmkasunich> since the actual calculations would be finished in less than 0.01 bit times
[03:37:33] <jmkasunich> fizz is mod 3 and buzz is mod 5, right?
[03:38:52] <jepler> something like that
[03:39:08] <jmkasunich> couple of johnson counters would do the trick I think
[04:03:00] <ejholmgren> no more fizzbuzz!
[04:03:39] <ejholmgren> that article did keep me awake during calc class tonight though
[04:09:58] <cradek> if I had to hire programmers, that would keep me awake too
[04:16:33] <cradek> I've never thought of myself as a programmer, but I must be one
[04:16:38] <cradek> http://www.mizzouse.com/2007/02/27/are-you-unfit-to-be-a-software-developer/
[04:16:54] <cradek> even the 'exercises' are trivially easy
[04:19:37] <jmkasunich> http://www.mizzouse.com/wp-content/uploads/2007/02/windowslivewritertop10weirdusbdrivesyouveneverseen-e3f6060618-1c3.jpg
[04:20:13] <cradek> ha
[04:20:24] <cradek> I like that one
[04:20:26] <jmkasunich> heres the whole list: http://gadgets.fosfor.se/the-2007-top-10-weirdest-usb-drives/
[04:22:00] <jmkasunich> http://www.digga.se/story.php?title=Juckande-USBminne
[04:23:18] <jmkasunich> I like the way they pixelated the plug
[04:23:25] <cradek> haha
[04:23:29] <cradek> that definitely makes the video
[04:24:25] <ejholmgren> wow
[04:25:15] <ejholmgren> that's one busy pooch
[06:13:51] <ds3> 3
[06:51:37] <Jymmmmmm> quiet in here lately at this time.
[08:03:28] <K`zan> Night all
[08:06:29] <Jymmmmmm> nit K`zan
[09:58:24] <jlmjvm> alex:good morning
[10:30:10] <alex_joni> jlmjvm: hi
[10:30:40] <jlmjvm> alex:hi
[10:31:24] <jlmjvm> I never had any luck getting the shuttle to work
[10:33:26] <alex_joni> sorry to hear that
[10:34:25] <jlmjvm> cant stat device() device dev/input/js0 is what is showing
[10:37:02] <alex_joni> somehow it doesn't get recognized
[10:37:14] <jlmjvm> hal : 20: pin joypad axis 0 does not exist
[10:37:39] <alex_joni> jlmjvm: if the device isn't recognized, no HAL pins get exported
[10:38:00] <jlmjvm> k
[10:38:24] <jlmjvm> wonder why its not recognizing
[10:39:00] <alex_joni> check dmesg
[10:42:17] <jlmjvm> how do i open in terminal like you were saying
[10:44:21] <jlmjvm> i found dmesg,want me to put on pastebin
[10:46:15] <jlmjvm> http://pastebin.ca/375495
[10:50:45] <alex_joni> jlmjvm: unplug the shuttle
[10:50:47] <alex_joni> then plug it again
[10:50:56] <jlmjvm> k
[10:55:24] <jlmjvm> http://pastebin.ca/375501
[10:55:49] <jlmjvm> heres the new dmesg with it plugged in
[11:02:50] <alex_joni> I don't see anything about the usb device
[11:03:07] <alex_joni> (don't start emc2.. just unplug/plug the shuttle)
[11:03:19] <jlmjvm> k
[11:03:33] <jlmjvm> done
[11:06:11] <alex_joni> pastebin?
[11:07:38] <jlmjvm> did you want me to restart emc after i unplugged/plugged and pastebin
[11:07:56] <alex_joni> no
[11:08:01] <jlmjvm> k
[11:08:07] <alex_joni> we don't care about emc now..
[11:08:11] <alex_joni> just unplug, plug the shuttle
[11:08:16] <jlmjvm> what did you want me to pastebin?
[11:08:18] <alex_joni> and pastebin the dmesg
[11:08:26] <jlmjvm> k,thats all i did
[11:08:30] <alex_joni> the USB device SHOULD appear there
[11:08:36] <jlmjvm> k
[11:08:45] <alex_joni> the one at 375501 ?
[11:09:16] <alex_joni> I don't see anything about USB there..
[11:09:27] <alex_joni> can you try another USB port?
[11:09:47] <jlmjvm> http://pastebin.ca/375512
[11:10:16] <jlmjvm> yes,want me to move
[11:10:44] <alex_joni> no, now it's ok
[11:10:59] <alex_joni> what hal files are you using?
[11:12:00] <jlmjvm> http://pastebin.ca/375515
[11:14:35] <alex_joni> I guess it's not a joystick then
[11:15:06] <jlmjvm> i was wonder if it was showing up as something different
[11:16:01] <alex_joni> yes, it shows up as a HID
[11:16:07] <alex_joni> Human Input device
[11:16:10] <jlmjvm> the device is working,the outer ring will scroll the page up and down
[11:16:22] <alex_joni> and I think it should be able to work with the new stuff jepler made
[11:16:29] <jlmjvm> yes,hid is what it uses in windows
[11:16:39] <jlmjvm> whats that
[11:16:44] <alex_joni> hal_input
[11:17:00] <alex_joni> it's a program that creates HAL pins for any input device linux knows
[11:17:10] <alex_joni> but I have little clue about it :)
[11:17:52] <jlmjvm> jepler has a program that does that?
[11:18:32] <alex_joni> yeah, he submitted it into emc2 TRUNK
[11:18:41] <alex_joni> so if you're running CVS you might be able to try it out
[11:18:51] <alex_joni> there is a manpage for it
[11:19:12] <jlmjvm> i can try
[11:19:28] <jlmjvm> ive never done a cvs yet
[11:20:17] <jlmjvm> where can i see the device manager in ubuntu?
[11:21:04] <alex_joni> in the menu somewhere
[11:21:08] <alex_joni> * alex_joni has no clue :D
[11:22:00] <alex_joni> jlmjvm: can you do "less /proc/bus/input/devices" and pastebin that?
[11:24:09] <jlmjvm> http://pastebin.ca/375535
[11:28:47] <jlmjvm> should all this be in 1 hal file,or should it be seperate and add a line to the ini file
[11:29:28] <alex_joni> did you unplug the shuttle?
[11:29:32] <alex_joni> it should be in that list
[11:30:05] <jlmjvm> its plugged in
[11:47:53] <alex_joni> jlmjvm_: sorry, I don't know..
[11:49:48] <jlmjvm_> i wlll try to talk to jepler later today about his program
[11:50:13] <jlmjvm_> i dont think linux is seeing it as a hid yet
[11:50:32] <jlmjvm_> is that what you think
[11:50:46] <alex_joni> I have no experience whatsoever with linux & hid
[11:50:59] <alex_joni> all I did before simply worked.. never had to start digging :)
[11:52:13] <jlmjvm_> you have used a shuttle with linux before?
[11:52:47] <alex_joni> no, but other HIDs
[11:52:52] <alex_joni> like USB mouses
[11:52:55] <jlmjvm_> ok
[11:53:34] <jlmjvm_> i bet this 1 will have to be built from the ground up
[11:58:59] <jlmjvm_> i wonder if i should try to load the software that came with it
[12:09:04] <jlmjvm_> i dont think linux is recognizing it as a hid,i wonder if fedora core 6 will see it?
[12:10:38] <alex_joni> [170081.745647] usb 4-4.4: new low speed USB device using ehci_hcd and address 6[170081.829433] input: Contour Design ShuttleXpress as /class/input/input5
[12:10:40] <alex_joni> [170081.829497] input: USB HID v1.10 Device [Contour Design ShuttleXpress] on usb-0000:00:10.3-4.4
[12:11:30] <jlmjvm_> was that what i put on pastebin earlier?
[12:12:54] <jlmjvm_> what is that?
[12:13:15] <alex_joni> yeah, from your dmesg
[12:13:34] <jlmjvm_> ok,guess linux is seeing it then
[12:14:00] <alex_joni> you might want to look around /proc/bus
[12:14:11] <alex_joni> and see maybe you get further intel from there
[12:14:36] <jlmjvm_> i have amd
[12:14:50] <alex_joni> intel = intelligence, aka information
[12:15:13] <jlmjvm_> lol,sorry
[12:15:32] <jlmjvm_> missed that one by a mile
[12:35:36] <jlmjvm_> i just found a file that says the id of this should be 0b33,does that mean anything/
[12:37:34] <alex_joni> not to me :)
[12:38:07] <jlmjvm_> k
[12:42:20] <jlmjvm_> if a servo motor says its 640 oz in,is the the same as 40 in lb
[12:46:06] <jlmjvm_> found some servo motors that are 600 oz in,but was wondering if they were strong enough for a bridgeport
[13:05:40] <skunkworks> does anyone know of anyone using the mesa board to run their machine?
[13:05:53] <skunkworks> websites would be great
[13:05:54] <alex_joni> skunkworks: not by name, but there are a few
[13:06:06] <alex_joni> (not from the group buy though)
[13:06:15] <skunkworks> morning alex.
[13:06:20] <alex_joni> hiya
[13:20:43] <jepler> jlmjvm_: this line means that the device is likely to be usable by the new hal_input: [170081.829433] input: Contour Design ShuttleXpress as /class/input/input5
[13:20:50] <jepler> however, hal_input is not a part of emc 2.1
[13:27:54] <skunkworks> this thread from yesterday now has a mind of its own
[13:27:57] <skunkworks> http://www.cnczone.com/forums/showthread.php?t=32832
[13:27:59] <skunkworks> :)
[13:28:47] <alex_joni> jepler: shouldn't it appear in /proc/bus/input/devices ?
[13:41:22] <jepler> alex_joni: yes, it should
[13:41:26] <jepler> did jlmjvm_ say it didn't?
[13:41:31] <alex_joni> yes
[13:41:37] <jepler> I didn't read any further back
[13:41:55] <alex_joni> 13:16 < alex_joni> jlmjvm: can you do "less /proc/bus/input/devices" and
[13:41:55] <alex_joni> pastebin that?
[13:41:55] <alex_joni> 13:18 < jlmjvm> http://pastebin.ca/375535
[13:44:55] <jepler> the other thing to do is "ls -l /dev/input" to see if an entry is created there when the device is plugged in (that's what hal_input actually uses)
[13:45:15] <jepler> but linux has to recognize the device before hal_input will use it
[14:00:07] <jlmjvm_> alex:http://pastebin.ca/375639
[14:00:27] <jlmjvm_> sorry was away for a minute
[14:02:04] <jlmjvm_> jepler:http://pastebin.ca/375640
[14:03:29] <jepler> jlmjvm_: looks like you have to resovle why the kernel doesn't recognize the shuttlexpress as an input device before there's even a question of how to use it with emc.
[14:03:42] <jepler> jlmjvm_: nobody here is an expert in that area
[14:04:33] <jlmjvm_> so the kernel isnt seeing the device
[14:06:24] <jepler> it sees it as a usb device, but not as an input device. There are probably several layers in the kernel between those two. At one of those layers, the right thing is not happening. But like I said, I am not an expert.
[14:07:54] <jlmjvm_> so this could possibly be added between the layers by somebody that knows kernels/
[14:08:09] <jepler> right
[14:09:02] <jlmjvm_> cool,i know where a couple of red hat developers work,may have to stop by for a visit
[14:09:42] <jlmjvm_> it need to 2.6.15 magma,right?
[14:11:24] <jlmjvm_> het wait a min,when i sent you the file a min ago i didnt have it plugged in
[14:11:26] <jepler> the short answer is "yes", because if you change kernel version you have to add the realtime patch to the new kernel and recompile emc2 -- not a lot of fun
[14:13:51] <jlmjvm_> jepler: new file http://pastebin.ca/375646
[14:15:34] <jepler> that is more promising. You'll notice that there is a new "event3" device in that list, compared to the earlier one.
[14:16:42] <jlmjvm_> i see it
[14:18:11] <jlmjvm_> do you want me to do "less /proc/bus/input/devices"
[14:30:21] <jlmjvm_> http://pastebin.ca/375662
[15:35:33] <fguden> Hello?
[15:35:39] <fguden> anyone here?
[15:39:58] <cradek> * cradek grumbles
[15:43:18] <alex_joni> cradek: ?
[15:43:29] <alex_joni> you mean the ask & run?
[15:43:38] <cradek> yeah, I think it's stupid
[15:43:54] <alex_joni> it might be that people don't know how IRC works
[15:44:06] <alex_joni> or they think that if it's silent there's no-one here
[15:46:14] <jlmjvm_> i know im new to irc
[15:46:24] <jlmjvm_> and linux also
[15:47:03] <cradek> jlmjvm_: nothing wrong with that
[15:47:37] <jlmjvm_> gotta step up to the plate sometime
[15:48:33] <jlmjvm_> im very pleased with the new version yall have made
[15:48:40] <cradek> cool
[15:48:51] <cradek> it had a bugfix that you needed?
[15:49:10] <jlmjvm_> yep,works good
[15:49:55] <jlmjvm_> when my new gecko gets in today im gonna cut something on my bridgeport
[15:50:09] <cradek> neat
[15:50:20] <cradek> is it an old stepper bridgeport?
[15:50:49] <jlmjvm_> how do you get to your tool offsets and fixture offsets using the axis gui
[15:50:54] <jlmjvm_> yes it is
[15:51:08] <jlmjvm_> series 1
[15:51:30] <cradek> you kept the original steppers with the big fins, but run them with geckos?
[15:51:40] <jlmjvm_> yes
[15:51:50] <cradek> how does that work out?
[15:52:32] <jlmjvm_> they are strong motors,but cant get em past 140 ipm
[15:52:48] <cradek> 140 isn't bad at all for old steppers
[15:52:51] <jlmjvm_> but for 100 ipm rapids they work good
[15:53:03] <jlmjvm_> not really
[15:53:10] <cradek> what supply voltage do you use?
[15:53:27] <jlmjvm_> about 65v dc
[15:53:56] <cradek> interesting, thanks, I've always wondered how one of those would run with just new drivers
[15:54:22] <cradek> for tool offsets, you just edit the tool table (something.tbl)
[15:54:38] <cradek> for a work offset, use the "touch off" button in AXIS
[15:54:39] <jlmjvm_> they run great if the motor isnt wore out
[15:55:22] <cradek> I bet they run a lot cooler with chopper drives
[15:55:40] <jlmjvm_> something.tbl ?
[15:55:51] <jlmjvm_> they dont get all that hot
[15:55:52] <cradek> in your config directory, you'll see a .tbl file
[15:56:48] <jlmjvm_> yes,mine is stepper.tbl
[15:57:32] <cradek> that's where you put your tool offsets for diameter and length
[15:57:50] <jlmjvm_> do you mean change the offsets in the .tbl file?
[15:58:02] <alex_joni> jlmjvm_: then you use M6Txx (xx=tool number) to change to the appropriate tool
[15:58:12] <jlmjvm_> now i see
[15:58:20] <alex_joni> jlmjvm_: the default file only has 4? examples
[15:58:24] <jlmjvm_> told ya i was new,lol
[15:58:26] <alex_joni> you will want to write all your tools there...
[15:58:30] <jlmjvm_> k
[15:58:43] <alex_joni> M6T1 will cause the machine to change to tool #1
[15:59:06] <alex_joni> (depending on the configuration that toolchange happens automatically, or needs to happen manually)
[15:59:14] <alex_joni> configuration, capabilities, etc
[16:00:16] <jlmjvm_> cool
[16:00:42] <jlmjvm_> can you have this file open while emc is running
[16:00:48] <alex_joni> yes
[16:00:53] <jlmjvm_> it is now
[16:00:56] <jlmjvm_> k
[16:01:01] <cradek> in AXIS there's a "reload tool table" on the machine menu
[16:01:05] <alex_joni> you have a button/menu entry somewhere in AXIS to reload tool table
[16:01:10] <alex_joni> what cradek said
[16:01:17] <cradek> what alex said
[16:01:26] <alex_joni> jlmjvm_: know how to handle recursion?
[16:01:38] <jlmjvm_> k,i saw that was fixing to ask about that
[16:01:55] <jlmjvm_> recursion?
[16:02:10] <alex_joni> yeah, a programming technique
[16:02:16] <cradek> programmer humor, never mind alex
[16:02:43] <jlmjvm_> over my head
[16:02:53] <alex_joni> jlmjvm_: probably too ahrd to explain anyways.. (the main idea was that if you look what I said was to look at what chris said, and he said to look at what I said, etc...)
[16:03:05] <alex_joni> that's a recurrent thing (like a loop)
[16:04:05] <jlmjvm_> now i see what your talking about,had missed that,was flipping between workspaces
[16:05:30] <jlmjvm_> as yall were saying that i was thinking how do you enter an offset once running after you change the .tbl file
[16:06:13] <alex_joni> you use touch-off for that (if I understand what you're asking)
[16:06:39] <cradek> I don't think I understand the question - can you give more detail
[16:07:50] <jlmjvm_> what i meant was if you run a tool,and measure work,and make an adjustment in the .tbl file,would it be active,and it should if you hit reload table
[16:08:21] <cradek> are you talking about coordinate system (work) offset, tool radius compensation, or tool length compensation?
[16:08:57] <jlmjvm_> tool length and radius compensation
[16:09:47] <cradek> you enable tool length compensation with G43, and you enable tool radius comp with G41/G42 and appropriate entry moves
[16:10:02] <cradek> that's after you load the tool data from the tool table
[16:10:41] <jlmjvm_> i fully understand that,been a cnc programmer for 24 years
[16:10:59] <cradek> ok great
[16:11:17] <cradek> if you change the tool table, you do have to tell EMC to reload it
[16:11:17] <jlmjvm_> what i meant was the tool offsets,say you make a cut and want it .005 deeper
[16:12:01] <jlmjvm_> do you adjust the tool offset,and reload table
[16:12:05] <cradek> yes you could do that by changing the tool length offset
[16:12:26] <jlmjvm_> wont you have to reload table
[16:12:30] <cradek> or you could jog/MDI to Z0 and use "touch off" entering 0.005
[16:12:52] <cradek> yes you have to reload the tool table after changing it
[16:13:06] <jlmjvm_> cool,sounds reasonable
[16:13:16] <cradek> do you have tool holders?
[16:13:31] <jlmjvm_> would mainly be doing that when sizing in cutter comp
[16:13:41] <jlmjvm_> yes,have 8 holders
[16:14:00] <cradek> good, you can stick the tools in them and just measure them once then
[16:14:19] <cradek> yeah I've tweaked the tool radius to get a part to size like that
[16:14:34] <cradek> length isn't so fiddly usually
[16:14:39] <jlmjvm_> its what you have to do on any mill
[16:15:45] <jlmjvm_> naw if you do a good setup the lengths are usually there
[16:15:44] <jlmjvm_> usually gotta adjust the comp though
[17:37:05] <ogarr> Need help setting up Ubuntu. Can anyone help?
[17:38:04] <skunkworks> ask away
[17:39:03] <CIA-6> 03jepler 07TRUNK * 10emc2/docs/src/Submakefile: create a PDF file containing all the manpages
[17:39:48] <ogarr> When I go to the start.exe it says "launching browser, please wait" Nothing happens.
[17:39:56] <CIA-6> 03jepler 07TRUNK * 10emc2/src/hal/components/lut5.comp: fix table in ps/pdf version of manpage
[17:40:49] <cradek> ogarr: you have to boot from the CD to install ubuntu
[17:40:50] <jepler> You install Ubuntu by booting from the CD, not by running start.exe in Windows.
[17:41:03] <ogarr> ahh, ok thanks
[17:41:28] <skunkworks> there is a start.exe on the ubuntu cd? odd
[17:41:34] <jepler> skunkworks: apparently -- that's news to me, too
[17:41:58] <jepler> I'm not surprised if cradek never made sure that it worked when he was preparing the emc version of the live cd
[17:42:32] <skunkworks> ah - cradeks fault. I understand.
[17:42:48] <jepler> that's my guess, anyway
[17:42:50] <skunkworks> :)
[17:42:56] <cradek> I think I removed that stuff to make room for important things
[17:43:03] <cradek> I must have missed some of it
[17:44:30] <skunkworks> * skunkworks left his 8 live cd's at home.
[17:45:19] <skunkworks> you can never have too many
[17:45:38] <jepler> for those of you who prefer paper and paper-like documentation: http://linuxcnc.org/docs/devel/EMC2_Manual_Pages.pdf
[17:47:35] <skunkworks> Hey - thats neet.
[17:47:38] <skunkworks> neat
[17:47:50] <CIA-6> 03jepler 07TRUNK * 10emc2/docs/src/Submakefile: new section 9 autogenerated manpages weren't being added to the HTML docs
[18:04:25] <CIA-6> 03jepler 07TRUNK * 10emc2/docs/src/Submakefile: put the manual pages in a sensible order in the PDF version
[19:41:53] <jepler> this might be a neat DIY project: http://blog.modernmechanix.com/2007/02/28/phonograph-record-is-made-on-paper/
[19:44:21] <jepler> hm -- if you can print and read the "samples" at 300/inch, you need to scan across 26.7 inches/second just to get 8000 samples/second
[19:55:54] <lerneaen_hydra> jepler; some type of mechanical fft?
[19:56:18] <lerneaen_hydra> or low-tech electronic components?
[20:00:33] <jepler> lerneaen_hydra: I think you just amplify the response of the photo sensor and play it on speakers
[20:01:00] <lerneaen_hydra> oh, I see
[20:03:33] <jepler> take the sound, resample to 8000/second. Print the "most negative" sample as 100% black, the "most positive" sample as 100% white, and the "zero" sample as 50% black / 50% white
[20:04:16] <lerneaen_hydra> oh, so similar to the system used on video film with audio? (varying width clear track)
[20:04:19] <jepler> right
[20:04:32] <jepler> put it on a cylinder and do a helical scan at 26.7 inches per second
[20:04:53] <jepler> but I don't think you'll get much sound on a piece of letter or A4 paper
[20:06:09] <lerneaen_hydra> what about rastered dots (digital) with some error correction? how many MB would you think that would be? 20mb B/W and 60 for color?
[20:06:40] <jepler> that's about 3 revolutions per second .. to get 100 different sound levels represented you need 1/3 inch, so that's 1 inch "down" the drum per second .. so only 11 seconds of audio per letter paper
[20:07:19] <jepler> if you do 600DPI it gets 4x better but you still don't have even 1 minute of AM-quality sound per sheet of paper
[20:07:42] <jepler> lerneaen_hydra: to read a digital code you'd need a much more complicated sensing system
[20:07:43] <lerneaen_hydra> wouldn't a digitalisation give quite a bit of space?
[20:07:44] <alex_joni> jepler: saw some nice 2400dpi printers lately
[20:07:52] <lerneaen_hydra> yeah, but with todays systems
[20:08:21] <jepler> for this all you need is a single sensor looking through a small slit, and it's all analog
[20:08:37] <skunkworks> * skunkworks hates analog
[20:08:47] <alex_joni> jepler: right, but using digital you could read a couple tracks at once
[20:08:56] <alex_joni> * alex_joni thinks of interleaved spiral
[20:09:06] <jepler> OK, I take it back, this would be a terrible DIY project
[20:09:11] <jepler> I bet it never worked in the first place :-P
[20:09:27] <alex_joni> we probably have higher expectations
[20:09:50] <alex_joni> phonographs didn't sound like DVDs.. did they :)
[20:10:05] <skunkworks> 1khz freqency responce is ok for voice ;)
[20:10:24] <jepler> ah -- I have a better idea
[20:10:24] <alex_joni> maybe so.. but 8kHz is crappy for music
[20:10:26] <lerneaen_hydra> hmm, if digitalised on paper and with .5mm squares you only get 30kb
[20:10:35] <alex_joni> lerneaen_hydra: 2400dpi
[20:10:54] <alex_joni> but it's a pita to read that back reliably
[20:11:10] <lerneaen_hydra> is that dots per linear inch or inch^2?
[20:11:19] <alex_joni> I think those 2D barcodes (datamatrix & co) are as good as it gets
[20:11:23] <alex_joni> lerneaen_hydra: linear inch
[20:11:29] <lerneaen_hydra> say that you can read it at 1200dpi reliably then
[20:11:35] <alex_joni> you'd have 2400x2400 per square inch
[20:11:49] <lerneaen_hydra> 1200 dpi -> 0.02mm dots
[20:12:18] <alex_joni> yup.. a PITA to read reliably
[20:12:18] <lerneaen_hydra> so 2500 dots per mm^2
[20:12:25] <jepler> get one of those old "high speed paper tape readers" (this one says 300 8-bit characters per second), and a microcontroller/fpga implementation of an ultra-low-bitrate voice codec to do audio from paper tape
[20:12:46] <alex_joni> paper tape?
[20:12:53] <jepler> http://www.pdp8.net/pc04/pc04.shtml
[20:12:54] <jepler> yeah
[20:13:23] <alex_joni> why not punch cards?
[20:13:34] <lerneaen_hydra> if you can read at 1200dpi you get 18.5mb per page
[20:13:38] <alex_joni> then to listen to a song, one would have to change 2.75 punchcards/second
[20:13:38] <skunkworks> alex_joni: that would be just crazy
[20:13:43] <skunkworks> ;)
[20:13:55] <alex_joni> lerneaen_hydra: no way you can do that reliably
[20:14:55] <alex_joni> datamatrix is .5mm I think
[20:15:09] <lerneaen_hydra> .1 shouldn't be too hard to do
[20:15:19] <alex_joni> lerneaen_hydra: to read it's hard
[20:15:29] <lerneaen_hydra> not with a modern scanner
[20:15:42] <lerneaen_hydra> 0.1 only gives you 760kb though
[20:16:02] <alex_joni> use a 500 page block
[20:16:15] <alex_joni> oh, and duplex printing :D
[20:16:31] <alex_joni> I like the tesa-stuff better
[20:16:37] <alex_joni> that's a better idea
[20:16:40] <lerneaen_hydra> 760mb for something around 100 times the volume of a CD
[20:16:54] <lerneaen_hydra> tesa?
[20:16:57] <alex_joni> they researched encoding data on tesa film
[20:17:05] <lerneaen_hydra> teas film?
[20:17:08] <alex_joni> using CD technology
[20:17:15] <alex_joni> lerneaen_hydra: scotch tape
[20:17:18] <alex_joni> transparent
[20:17:25] <lerneaen_hydra> microfilm?
[20:17:26] <alex_joni> laser in the middle, rotating
[20:17:38] <alex_joni> lerneaen_hydra: no, regular sticky tape
[20:17:49] <jepler> with or without the adhesive?
[20:17:49] <alex_joni> you have lots and lots of meters on one small roll
[20:17:55] <lerneaen_hydra> standard scotch tape?
[20:17:55] <alex_joni> jepler: with
[20:18:01] <alex_joni> lerneaen_hydra: yeah, standard
[20:18:10] <lerneaen_hydra> how'd they encode the data?
[20:18:12] <alex_joni> they used a laser and focal control to focus on each layer
[20:18:23] <alex_joni> small burn and it would bump
[20:18:28] <alex_joni> and that can be read back
[20:18:39] <alex_joni> 4-5GB / scotch tape roll
[20:18:45] <alex_joni> few cents
[20:18:47] <lerneaen_hydra> the tape physically deforms?
[20:18:50] <alex_joni> perfect technology
[20:18:53] <lerneaen_hydra> from the heat?
[20:19:01] <alex_joni> lerneaen_hydra: it creates a bubble (blister)
[20:19:04] <lerneaen_hydra> oh, ok
[20:19:07] <alex_joni> yeah, from heat
[20:19:12] <lerneaen_hydra> they must be very, very small to get 4-5gb
[20:20:18] <alex_joni> I think a roll of tesa is about 30-40m x 19mm wide
[20:22:05] <alex_joni> found an online article (in german)
[20:22:17] <alex_joni> it seems there are about 30 um between sheets
[20:22:22] <alex_joni> easily doable with laser
[20:22:36] <lerneaen_hydra> what about the blister's size?
[20:23:21] <alex_joni> very small
[20:23:31] <alex_joni> they say it doesn't affect the neighboring layers
[20:23:43] <alex_joni> max. theoretical data size is 10GB
[20:23:47] <alex_joni> but they aim for 3-4
[20:23:50] <lerneaen_hydra> sounds about right
[20:25:09] <alex_joni> http://spiedl.aip.org/getabs/servlet/GetabsServlet?prog=normal&id=PSISDG005380000001000584000001&idtype=cvips&gifs=yes
[20:25:14] <alex_joni> google for tesa-ROM
[20:25:23] <alex_joni> (tesa is a german manufacturer like scotch)
[20:27:06] <alex_joni> the bad news is that they showed it on CeBit (a large german fare)
[20:27:17] <alex_joni> but that was in 1999.. not much happened since
[20:31:24] <alex_joni> lerneaen_hydra: found a note about "Recent progress in electron beam mastering for 100Gb/in^2 and beyond"
[20:37:29] <alex_joni> * alex_joni talks too much
[20:37:57] <lerneaen_hydra> 100gb/in²
[20:37:58] <lerneaen_hydra> nice
[20:38:03] <lerneaen_hydra> what substrate?
[20:38:11] <lerneaen_hydra> something relatively inert and stable I assume
[20:39:18] <ogarr> Does EMC2 support USB?
[20:39:33] <lerneaen_hydra> what do you mean by usb?
[20:39:41] <lerneaen_hydra> a usb paralell port?
[20:41:17] <jepler> ogarr: no, emc2 does not support controlling motors through a USB port
[20:42:36] <ogarr> THanks jepler
[20:54:39] <CIA-6> 03jepler 07TRUNK * 10emc2/src/hal/components/lut5.comp: lut5 didn't work right for functions higher than 0xff
[20:55:45] <jepler> I figured it was smooth sailing after I saw that functions 0, 1, and 6 all worked .. but I was wrong
[21:01:11] <anonimasu> hm
[21:01:22] <anonimasu> I've cut stuff with the plasma/oxyfuel machine today
[21:02:02] <anonimasu> the only issue is that I need another drive belt on the X axis..
[21:02:19] <anonimasu> to make it stiffer..
[21:05:26] <alex_joni> nice
[21:05:38] <alex_joni> so.. is that emc?
[21:08:44] <anonimasu> emc?
[21:08:46] <anonimasu> running emc?
[21:08:45] <anonimasu> yeah..
[21:09:11] <anonimasu> bought sheetcam to do the nesting..
[21:09:28] <alex_joni> nice
[21:09:33] <alex_joni> how good is it nowadays?
[21:09:45] <alex_joni> I used sheetcam when it was beta/free
[21:09:49] <anonimasu> not _extremely_ but it's easy to use and wseems to work really well..
[21:09:57] <anonimasu> I'd want it to do automatic nesting..
[21:09:57] <alex_joni> nice..
[21:09:59] <anonimasu> that's the only bad thing
[21:10:07] <alex_joni> anonimasu: for <1k$ ?
[21:10:15] <anonimasu> $1k?!
[21:10:15] <alex_joni> kidding.. right?
[21:10:16] <anonimasu> ffs..
[21:10:21] <anonimasu> sheetcam is like 140eur..
[21:10:29] <alex_joni> yeah, I know
[21:10:33] <alex_joni> auto nesting is 4k+
[21:10:39] <anonimasu> alex_joni: yeah, I'd love it to handle that..
[21:10:52] <anonimasu> I dont get it why it's so expensive..
[21:11:06] <alex_joni> anonimasu: because people are willing to pay that
[21:11:09] <alex_joni> :))
[21:11:18] <alex_joni> this is great: http://blog.modernmechanix.com/2007/01/22/batteries-of-robots-scoop-power-from-sea-with-shovels/
[21:11:31] <anonimasu> alex_joni: well, as long as it gives me toolpaths for little work :)
[21:12:10] <anonimasu> I need 40 parts of one kind 20 of another 30 of a third... and 10 of something..
[21:12:24] <anonimasu> a sheet of each kind of thickness approximately
[21:13:34] <alex_joni> anonimasu: there are SW out there that can easily handle that
[21:13:43] <alex_joni> along with keeping track what you have in your storage
[21:13:51] <anonimasu> it's not worth the hassle..
[21:13:53] <alex_joni> including scraps from older cuts
[21:13:59] <anonimasu> or the cash for it..
[21:14:11] <anonimasu> this is one full run.. of parts..
[21:14:14] <alex_joni> so you just tell it what you want to cut.. and it'll tell you what to use :D
[21:14:53] <anonimasu> plasma is overrated for thick stuff.. :/
[21:15:29] <alex_joni> anonimasu: how thick?
[21:15:34] <anonimasu> 30mm
[21:15:51] <alex_joni> 100A
[21:16:01] <anonimasu> too small machine ofcourse..
[21:16:09] <alex_joni> I just had a request for 60mm the other day
[21:16:12] <anonimasu> it cuts but not at sane feeds..
[21:16:25] <alex_joni> guess how much such a machine is :P
[21:16:31] <anonimasu> 40000eur?
[21:16:44] <anonimasu> err 40k eur..
[21:16:45] <alex_joni> nah, half
[21:16:49] <anonimasu> heh..
[21:16:52] <anonimasu> oxyfuel ftw!
[21:16:54] <alex_joni> plasma only
[21:17:01] <alex_joni> 300A, 300V :P
[21:17:06] <anonimasu> bah..
[21:17:11] <alex_joni> 450kg machine
[21:17:16] <anonimasu> that sucks really..
[21:17:32] <alex_joni> well.. if you need it :)
[21:17:36] <anonimasu> heh
[21:18:06] <anonimasu> yeah, but I'm comparing to the oxyfuel torch we are running that cuts 30mm like butter..
[21:18:30] <anonimasu> with no noticeable kerf..
[21:18:42] <anonimasu> :)
[21:18:49] <alex_joni> oxy is nice for thick stuff
[21:19:04] <alex_joni> seen 3500mm cut once
[21:19:12] <alex_joni> :-P
[21:19:18] <anonimasu> hehe
[21:19:59] <alex_joni> guess 30mm is nothing compared to that
[21:20:11] <anonimasu> we've got a torch for extremely thick stuff somewhere..
[21:20:21] <anonimasu> runs on LPG instead of acetylene
[21:20:47] <alex_joni> for extremely thick stuff, you use a 'lance' (I think it's called)
[21:21:48] <anonimasu> ok?
[21:22:02] <anonimasu> still, oxyfuel seems to work damn well, compared to the price..
[21:22:08] <alex_joni> looks like a meter long stick
[21:22:18] <alex_joni> yeah, can't beat the price..
[21:22:26] <alex_joni> but some need the quality or speed
[21:22:32] <alex_joni> especially under 30mm
[21:22:50] <anonimasu> yeah..
[21:22:58] <anonimasu> but thoose people probably arent cheaping out building machines themselves either :)
[21:23:07] <alex_joni> I reckon so..
[21:23:18] <alex_joni> seen people cutting with a laser up to 20mm
[21:23:23] <alex_joni> that's a LOT of power
[21:23:23] <anonimasu> did you hear the quote we got for a machine?
[21:23:33] <alex_joni> how big?
[21:23:35] <alex_joni> the machine
[21:23:35] <anonimasu> 14000eur.. 2x1m..
[21:23:44] <anonimasu> or was it 3x2..
[21:23:45] <alex_joni> 2x1 is tiny
[21:23:45] <anonimasu> oxyfuel..
[21:23:54] <anonimasu> or plasma(without powersupply and stuff)
[21:24:02] <anonimasu> without a cnc control..
[21:24:08] <anonimasu> optical eye..
[21:24:25] <alex_joni> yuck
[21:24:39] <anonimasu> yeah..
[21:24:52] <alex_joni> that price would be ok for a CNC 3x2m
[21:24:58] <alex_joni> plasma
[21:25:08] <anonimasu> yeah
[21:25:14] <anonimasu> that
[21:25:40] <a-l-p-h-a> did google change it's format from yesterday to today?
[21:26:42] <anonimasu> alex_joni: nothing's as nice as to watch your machine make parts :)
[21:26:52] <anonimasu> alex_joni: though im a bit too busy to really enjoy it
[21:27:15] <jepler> a-l-p-h-a: looks about the same to me
[21:27:41] <alex_joni> anonimasu: I know how that goes
[21:30:08] <anonimasu> now the only issue is getting height sensing..
[21:30:20] <anonimasu> and automating ignition cut/idle flame :)
[21:31:04] <anonimasu> http://en.wikipedia.org/wiki/Thermic_lance
[21:31:04] <alex_joni> anonimasu: for plasma?
[21:31:11] <alex_joni> yeah that..
[21:31:38] <anonimasu> alex_joni: no oxyfuel..
[21:31:56] <anonimasu> alex_joni: though I'm not sure if we really need it..
[21:32:13] <anonimasu> alex_joni: it dosent seem to be as sensitive as people say
[21:32:41] <alex_joni> what's your deviation?
[21:32:55] <alex_joni> for those 'small' plates it shouldn't be too much
[21:33:04] <alex_joni> but a 12mx3m sheet might have some bends in it
[21:33:15] <anonimasu> yeah..
[21:33:26] <anonimasu> well, I cut 2mm from the plate now..
[21:34:26] <anonimasu> im pondering about ultrasonic for the height sensing..
[21:35:05] <alex_joni> plasma is nicer.. with voltage control :)
[21:35:30] <alex_joni> anonimasu: I saw some article once for oxyfule that used a webcam to analyze the flame size
[21:36:13] <alex_joni> oxyfuel
[21:36:17] <anonimasu> yep
[21:37:06] <anonimasu> alex_joni: it's too bad the plasma wouldnt cut thick stuff easily..
[21:37:23] <anonimasu> :)
[21:37:27] <alex_joni> a big one would
[21:37:32] <alex_joni> but it's too much $$
[21:37:36] <anonimasu> bah, so would a laser..
[21:37:36] <anonimasu> ;)
[21:37:45] <anonimasu> or a waterjet
[21:37:46] <alex_joni> a 50mm machine costs double than a 40mm one
[21:38:17] <anonimasu> yep
[21:38:43] <alex_joni> I have a small handcarried unit that does 45mm
[21:38:49] <alex_joni> but it struggles
[21:39:38] <Jymmmm> iirc, pier was inq about hotwire cnc w/ emc, but sounded like emc couldn't do it. Is this true?
[21:40:40] <alex_joni> depends on what you mean..
[21:40:44] <Jymmmm> alex_joni small handed carried unit that does 45mm... Don't most folks call that a gun?
[21:40:48] <alex_joni> don't remember what pier wanted
[21:40:55] <alex_joni> Jymmmm: for plasma cutting
[21:41:50] <Jymmmm> Pier wanted to use emc to do hot wire foam cutting with tapered cuts. 4 motors
[21:41:57] <Jymmmm> err axis
[21:42:02] <alex_joni> joints :)
[21:42:08] <Jymmmm> bong hits
[21:42:11] <alex_joni> XY above, XY below?
[21:42:17] <alex_joni> wire between?
[21:42:18] <Jymmmm> side by side
[21:42:32] <Jymmmm> just a sec, will grab pics
[21:43:09] <Jymmmm> something like this... http://www.foamlinx.com/fc2913.html
[21:44:42] <tomp> what would he use to describe the motion? gcode? G1 X Y x y ??? not in the interpreter (or kins)
[21:44:53] <Jymmmm> http://www.deskcnc.com/Airfoil_Tutorial.html
[21:45:21] <Jymmmm> He said that he wrote it manually (not sure exactly what that means though)
[21:46:06] <cradek> I think xyuv is normal for foam cutting wire
[21:46:18] <cradek> (uv would be ab in emc)
[21:46:25] <Jymmmm> cradek: including a tapered cut?
[21:46:38] <cradek> yes to do a taper, u,v != 0
[21:46:56] <Jymmmm> cradek sorry, just learning here, no clue what that means.
[21:47:36] <Jymmmm> I just have all the parts to make a foam cutter, thought I would.
[21:47:48] <jepler> Jymmmm: the motors on one side are (X,Y) and on the other side (X+U, Y+V)
[21:48:04] <jepler> Jymmmm: so U,V determine the "slant" of the wire
[21:48:14] <Jymmmm> jepler gotcha
[21:48:35] <Jymmmm> So, this is something that's fairly striaght forward?
[21:48:38] <tomp> yeah, i know the forms, i work with airfoils a lot, turbine blades... if he can get what he wants to motion, then emc/hal can do it, it wont be normal gcode for 2 different curves top & bottom, or for when one pair needs to preceed the other ( lean into the direction of the curve ), he looses some of emc that way but can get what he needs
[21:48:51] <cradek> wow that doesn't look like $3000 worth of stuff
[21:49:05] <alex_joni> 300$?
[21:50:11] <Jymmmm> cradek: It's an "out the door, ready to go" package.
[21:50:34] <cradek> yeah that's worth something I guess
[21:50:49] <jepler> "High Torque - 110oZ*Inch"
[21:50:59] <cradek> it only has to move a wire...
[21:51:20] <Jymmmm> Big time, you are putting the tequilia/asprin money into the machien w/o the headaches/hangovers =)
[21:51:23] <jepler> Cutting speed: 16"/min
[21:51:39] <Jymmmm> jepler you dont want to cut foam too fast/slow
[21:51:54] <Jymmmm> they have videos on that page
[21:52:06] <Jymmmm> http://www.foamlinx.com/FAQ.html
[21:52:26] <Jymmmm> brb.... coffee
[21:55:41] <alex_joni> At the moment Foamlinx machines do not support automatic heat
[21:55:43] <alex_joni> control
[21:55:52] <alex_joni> I would expect that for 3k$
[22:00:46] <skunkworks> I just streched a piece of mig wire between the headstock and tail stock of our lathe and used 2 patterns on each end of the foam to make the airfoil ;)
[22:01:41] <alex_joni> did you heat it up?
[22:02:26] <Jymmmm> Eeeeesh... grow the beans, harvest the beans, roast the beans, grind the beans, brew the beans....
[22:02:40] <jepler> so on this kind of machine, the wire length is maintained simply by a spring? how well can that possibly work?
[22:03:03] <Jymmmm> alex_joni: Yeah, I thought that maybe I could use spindle control within emc for heat control.
[22:03:13] <skunkworks> alex_joni: I had a 30amp variable power supply iirc
[22:03:26] <Jymmmm> jepler hotwire stretch when heated, the spring is just to maintain tension.
[22:03:43] <skunkworks> jepler: That is what I did to keep tension on the wire - spring on one end.
[22:04:12] <cradek> I bet if you're cutting the right speed, the foam barely touches the wire
[22:04:40] <Jymmmm> cradek and if you're going to slow you get this BIG hole too =)
[22:04:56] <cradek> yeah I bet
[22:05:02] <jepler> I was thinking of the length change of the wire as you do moves in UV
[22:05:19] <alex_joni> sounds like a jog for temp-meter and adaptive FO
[22:05:27] <alex_joni> jepler: spring
[22:05:31] <Jymmmm> jepler I'd think a longer spring would compensate for that (within limits of course)
[22:05:40] <tomp> about the 5th picture can be enlarged to show how the motion gets tricky with airfoils ( velocity of xy not same as x'y', entry angle not normal to surface... ) http://www.peps.com/products/wire.htm#
[22:06:11] <Jymmmm> jepler Personally, I was thinking about using a idler wheel on a spring loaded slide.
[22:06:38] <Jymmmm> tomp which link?
[22:06:46] <Jymmmm> nm

[22:11:27] <ogarr> Does EMC2 support a serial connection to the motors?
[22:11:49] <alex_joni> ogarr: I haven't seen motors with serial interface
[22:11:58] <alex_joni> except CAN or Profibus maybe
[22:13:38] <skunkworks> ogarr: where you able to boot into ubuntu?
[22:13:55] <ogarr> I'm trying to figure out how to connect to a PDF or a maybe a Crystalfont unit
[22:14:08] <ogarr> Yes, I got ubutu up and running
[22:14:47] <alex_joni> ogarr: it depends what they expect on the serial line
[22:14:56] <jepler> ogarr: the "HAL User Manual", chapter 6, details the hardware interfaces supported by emc2. http://linuxcnc.org/docs/2.1/HAL_User_Manual.pdf
[22:15:15] <alex_joni> as it is now, emc2 doesn't work with serial devices.. but depending on what you need it can be hard or easy
[22:15:31] <ogarr> Thanks, I just downloaded the manual.
[22:16:21] <jepler> emc2 lets you write drivers for new hardware, but it requires considerable knowledge and the ability to write code in C.
[22:16:51] <ogarr> Which is WAY beyond me.
[22:16:53] <alex_joni> * alex_joni requires considerable sleep
[22:16:56] <alex_joni> good night all
[22:17:01] <anonimasu> night
[22:17:05] <tomp> gnite
[22:17:09] <ogarr> night alex
[22:17:17] <Jymmmm> alex_joni http://www.hotwiredirect.com/files/videos/TaperedDemo_High.wmv
[22:17:41] <cradek> g'night alex
[22:18:05] <skunkworks> ogarr: or... If you donate hardware to the developers - they will most likely write a driver for you. If you ask them really nice also.
[22:18:28] <ogarr> How many ways can I say please? LOL
[22:18:48] <Jymmmm> ogarr cash, check, charge, first born, etc =)
[22:19:09] <ogarr> I have to check with my partner. We need to decide on a route to take before we go into production.
[22:19:31] <jepler> choosing an existing, working hardware interface is probably the best idea
[22:20:19] <jepler> (working with emc2, that is)
[22:20:25] <tomp> Jymmmm: nice vid
[22:20:59] <Jymmmm> tomp: Yeah, no doubt.... no cad/cam either.... all programed from the pendant. eeeeeessh
[22:22:08] <Jymmmm> check out the pics at the bottom.... eeeeesh http://www.hotwiredirect.com/products/cnc-foam-cutting-machines/
[22:23:44] <ogarr> Any idea what kind of a price on those machines, Jymmmm?
[22:25:39] <Jymmmm> ogarr no idea, at least one comma =)
[22:25:59] <tomp> a buddy needed that wedm lathe idea, but had xyuv machine. so he sacrificed the y for a rotary ( just pulled the motor out and connected to table top mounted rotary with a live ctr opposite ) and was able to 'turn' work, he just had to lie a lot to the control ( Ed Vilchez, near 1980 ) limited but did what he needed
[22:31:36] <tomp> Jymmmm: i'd be very interested how your friend pumps the data into emc ( how he requests position without using gcode ).
[22:36:11] <Jymmmm> tomp: It's Pier in here. So catch him when he's here, or send him a memo
[22:36:21] <tomp> cool, thanks
[22:36:22] <Jymmmm> /ms help
[22:36:38] <Jymmmm> (if he's registered that is)
[22:41:22] <tomp> Jymmm: Pier: http://imagebin.org/7424
[22:49:50] <Jymmmm> Ok, just got off the phone... the 8700 goes for $40K USD, runs on servos, can do 6 wires at a time, comes with BobCad, and three days of onsite setup and training.
[22:50:39] <Jymmmm> Ya know, that's really not that expensive when you think about it.
[22:51:08] <Jymmmm> the onsite stuff is included in the price, I know lots of places that charge extra for that.
[22:51:33] <Jymmmm> tomp what are those pics of (specifically)?
[22:52:12] <Jymmmm> Teasers? LOL
