[00:30:57] <toastydeath> does anybody know a fly that has yellow coloration
[00:31:08] <toastydeath> that's just under 1/2" long
[00:31:12] <toastydeath> or maybe over
[00:32:44] <ds2> I don't make friends with flys! :)
[00:33:07] <CIA-2> 03jepler 07TRUNK * 10emc2/configs/sim/sim.tbl: add newline expected by rs274 sai
[00:34:28] <CIA-2> 03jepler 07TRUNK * 10emc2/src/emc/sai/driver.cc: for RIP systems, make the sim.var and sim.tbl files be found automatically
[00:40:50] <JymmmmEMC> toastydeath: any black rings/stripes?
[00:42:08] <JymmmmEMC> if so, sounds like baby wasp
[00:50:30] <toastydeath> nah
[00:50:34] <toastydeath> it was a flesh fly
[00:51:23] <toastydeath> there was a bird's nest in a crack in the outer wall
[00:51:26] <toastydeath> one of the birds may not have survived
[00:51:36] <toastydeath> which would explain the flesh fly
[00:51:53] <CIA-2> 03jepler 07TRUNK * 10emc2/src/hal/classicladder/ (6 files): change these files from DOS line endings to UNIX. no substantive changes.
[00:54:30] <Twingy> heh, just got 5,000 resistors and 1300 capacitors for under $30
[00:57:49] <JymmmmEMC> Twingy: Cool. Good selection I hope
[00:57:55] <Twingy> it's a kit
[00:58:01] <Twingy> all different sizes
[00:58:11] <JymmmmEMC> nice
[00:58:18] <skunkworks> where?
[00:58:22] <Twingy> ebay of course
[00:58:26] <skunkworks> darn
[00:58:34] <Twingy> he's got more though
[00:58:38] <skunkworks> link?
[00:59:32] <Twingy> http://search.ebay.com/_W0QQsassZapmmall.engineeringQQhtZ-1
[01:00:08] <JymmmmEMC> not SMT?
[01:03:13] <Twingy> it is SMT
[01:03:16] <Twingy> look closely
[01:03:35] <JymmmmEMC> I saw, thought they were thru hole
[01:03:41] <jmkasunich> oh, so the entire collection fits in a thimble?
[01:29:33] <tomp> i just had to install netscape9 to get internet bill paying. the bank (Chase) dropped firefox support when some tiny jsp script didnt run. So they dropped it rather than fix it :( i didnt know Netscape still existed.

[02:22:24] <The_Ball> jepler, How are you? How is the PCI-8255 working for you?
[02:23:41] <The_Ball> BTW, I solved my step problems:
http://wigen.net/cncsetup3.jpg
[02:32:13] <lewin1> lewin1 is now known as lewing
[02:40:20] <tomp> The_Ball: congrats, I can see a Tux carved in there :) what fixed the problem?
[02:54:57] <The_Ball> tomp, I tried using step/dir, cw/ccw steps, but both modes were losing steps. Using Q4 mode fixed it. Now im also using two schmitt triggers inverted, so one line goes high one goes low, as the drives prefer a balanced input over a single ended
[02:55:49] <tomp> :) great!
[02:56:41] <The_Ball> yeah, im really happy, now I have to learn some gcode and some machining "skills"
[03:01:52] <Jymmm> The_Ball: First lesson..... MORE DUCT TAPE!!!!!
[03:03:23] <The_Ball> tomp, I don't know if you can see the first tux trial, was with a 10mm end mill, and it came out skewed because of the lost steps, the second trial is good, that was with a 10mm drill bit, i don't have a ball mill
[03:03:28] <The_Ball> Jymmm, haha, that's very true
[03:04:30] <Jymmm> The_Ball: Well, you MIGHT try a dremel ball endmill till you have a chance to buy something good
[03:04:43] <Jymmm> even HD and lowes sell them now.
[03:05:14] <The_Ball> I'm in .au so I'm don't know those stores, but I should be able to get a hold of some soon
[03:05:21] <toastydeath> a ball endmill or a burr?
[03:05:50] <Jymmm> The_Ball: Ah, well have hardware store then
[03:06:03] <Jymmm> toastydeath: anything other than a drillbit =)
[03:06:58] <toastydeath> lol
[03:07:11] <toastydeath> TOUCHE SIR
[03:07:56] <Jymmm> Though I will say that rotobiits don't work too shabby for Q&D stuff as long as you don't go too fast.
[03:08:10] <tomp> burr ng in wood, maybe

[03:12:14] <jepler> The_Ball: I am not actually using the pci-8255 board for anything ..
[03:12:36] <jepler> The_Ball: I guess I would not be surprised if there are bugs in it
[03:26:25] <The_Ball> jepler, ok, but it is a general ("slow") IO card right?
[03:27:15] <CIA-2> 03swpadnos 07TRUNK * 10emc2/src/hal/utils/ (meter.c miscgtk.c): Add accelerator keys to halmeter main window and signal selection window
[03:41:45] <jepler> The_Ball: yes
[04:01:46] <Skullworks-PGAB> RE CSS
[04:01:56] <toastydeath> is that like the matrix: reloaded
[04:02:08] <toastydeath> except now with 100% less gunfights
[04:04:56] <Skullworks-PGAB> Initial Call of a G96 requires an Sxxxx value then is cancelled by a G97 - G97 the Sxxxx is optional and machine will remain at the last calculated speed if a fixed Sxxxx value is not stated.
[04:05:48] <Skullworks-PGAB> after first call G96 can be modal using prior defined value.
[04:09:14] <toastydeath> also don't forget to cap the spindle speed
[04:09:21] <toastydeath> lulz
[04:09:22] <Skullworks-PGAB> right
[04:09:32] <Skullworks-PGAB> G50 defines max spindle rpm
[04:10:34] <Skullworks-PGAB> and should be defined prior to a G96 - or an alarm/error code should be generated
[04:11:48] <Skullworks-PGAB> however - the default max spindle rpm for each m41/m42 could be defined in the ini file.
[04:16:25] <toastydeath> on real nice iron with a good chuck or collet system
[04:16:29] <toastydeath> you could always just let it spool out
[04:16:33] <toastydeath> until it hits the machine limit
[04:16:42] <toastydeath> 10k or whatever
[04:17:23] <Skullworks-PGAB> big mazak lathe at work had a spindle runaway
[04:17:50] <toastydeath> loud bang?
[04:17:59] <Skullworks-PGAB> encoder board shorted so amp kept dumping more power at it
[04:18:08] <toastydeath> ha
[04:18:33] <toastydeath> what ended it
[04:18:37] <Skullworks-PGAB> it was heading for 7xxx when it tripped the servo amp breaker
[04:18:45] <toastydeath> hahahah jesus
[04:18:51] <toastydeath> how big of a chuck
[04:18:58] <Skullworks-PGAB> last time
[04:18:58] <toastydeath> i'm assuming a chuck, anyway
[04:19:00] <Skullworks-PGAB> 12"
[04:19:04] <toastydeath> nice
[04:19:12] <toastydeath> that's not small hardware to be moving at 7k
[04:20:10] <The_Ball> hi Skullworks, got it all going now :)
[04:20:11] <Skullworks-PGAB> last time it had a big jaw set - the jaw bolts sheared and the sheetmetal had the be cut off - door and way covers
[04:20:34] <Skullworks-PGAB> yes - I was very luck
[04:20:41] <Skullworks-PGAB> lucky

[04:23:33] <jepler> (also I improved error handling)
[04:28:24] <Skullworks-PGAB> Ball: - yeah I read back thru the last 36 hrs and caught that.
[04:29:07] <The_Ball> ah ok, not to much traffic in this channel
[04:31:12] <Skullworks-PGAB> its kinda obscure - nice thing is - those here DO know what your talking about and can spot issues quick when given complete and clear details.
[04:31:27] <CIA-2> 03cradek 07TRUNK * 10emc2/src/emc/kinematics/tp.c: remove debugging statement
[04:34:01] <Skullworks-PGAB> so what are they doing on the Mazak now?
[04:35:41] <The_Ball> You are right about that!
[04:44:39] <jepler> Skullworks-PGAB: they moved the table, and then they started trying to figure out what state the spindle and tool changer are in
[04:44:51] <jmkasunich> axis control works
[04:44:54] <jepler> and now I think we're all about to quit for the night
[04:44:59] <jepler> I know I am
[04:45:22] <jmkasunich> spindle gear-change logic seems a bit squirrely, need to double check it before we run it more
[04:45:45] <jmkasunich> I suspect that some classicladder changes from 2.1 to 2.2 might need to be accounted for
[04:46:08] <jmkasunich> but we ran the Axis splash screen just fine
[04:49:03] <Skullworks-PGAB> great
[04:50:59] <The_Ball> jmkasunich, do you have a picture of this machine?
[04:51:16] <Skullworks-PGAB> http://linuxcnc.org/compile_farm/festcam.shtml
[04:52:17] <Skullworks-PGAB> they just bailed out - but it IS late there
[05:00:36] <The_Ball> big machine!
[05:00:51] <toastydeath> aww it's a baby!
[05:01:46] <The_Ball> time to go get some alu stock, see ya later
[05:02:53] <Skullworks-PGAB> Snooze time for me too.
[05:03:17] <toastydeath> i don't think purchasing aluminium is slang for "sleeping"
[05:03:20] <toastydeath> but whatever!
[05:47:06] <Jymmm> What are most using to draw up wiring diagrams?
[06:07:54] <wholepair> wine + Mastercam ???
[06:28:50] <alex_joni> Jymmm: gEDA or Eagle
[06:29:25] <Jymmm> alex_joni: eagle does electrical?
[06:29:32] <Jymmm> alex_joni: and g'morning
[06:35:21] <alex_joni> Jymmm: it should.. I usually use Orcad
[06:35:28] <alex_joni> good morning indeed
[06:40:04] <wholepair> Oregon-cad - blah
[07:06:56] <The_Ball> does anybody know what the "Offset Distance" is used for in gcam?
[07:07:15] <The_Ball> It's a "Bolt Holes Parameter"
[07:07:46] <The_Ball> And it defaults to 10mm which doesn't make sens (to me)
[07:57:48] <alex_joni> Jymmm: you do graphics sometimes?
[08:52:39] <Jymmm> alex_joni:
[08:52:44] <Jymmm> alex_joni: yes
[08:53:03] <Jymmm> quite often actually
[08:58:47] <alex_joni> Jymmm: was wondering if you know a site with car graphics
[08:58:53] <alex_joni> I mean stuff to put on your car
[09:19:13] <Jymmm> alex_joni: Such as?
[09:19:22] <Jymmm> flames?
[09:31:14] <alex_joni> & stuff
[09:31:17] <alex_joni> yeah
[09:44:38] <Jymmm> alex_joni: vinal?
[09:45:24] <Jymmm> I'll see what I have, You want vector or raster graphics?
[11:07:50] <The-Ball> Im doing my first proper cut in my mill now, a quill clamp to hold a dremel for pcb milling and drilling, out of a 20mm thick alu plate, and it's looking very good! :D
[11:10:55] <Bo^Dick> The-Ball: have you built the equipment?
[11:13:59] <The-Ball> no, a mill conversion.
http://wigen.net/cncsetup.jpg http://wigen.net/cncsetup2.jpg http://wigen.net/cncsetup3.jpg
[11:15:18] <Bo^Dick> that's really cool
[11:15:37] <The-Ball> I love it, this is a new world for me
[11:16:20] <Bo^Dick> i wish i had a mill to convert myself
[11:16:29] <Bo^Dick> btw, that mill looks pretty large
[11:16:42] <The-Ball> you can get a small one and drive it with steppers
[11:16:47] <The-Ball> it's about 300kg
[11:17:06] <Bo^Dick> wow
[11:17:43] <anonimasu> heh
[11:17:43] <Bo^Dick> but real mills are more accurate than those aluminium bar cnc setups
[11:17:47] <The-Ball> that's what the shipping weight said, so it's probably more like 250 or so
[11:18:01] <anonimasu> that's a pretty small mill
[11:18:06] <anonimasu> ^_^
[11:18:16] <The-Ball> yes, they are more rigid if you need to work on metal
[11:18:21] <anonimasu> * anonimasu nods
[11:18:35] <The-Ball> anonimasu, that's for sure, everything is relative
[11:18:52] <anonimasu> I have one like that for sale
[11:18:52] <The-Ball> but it's big enough for me when i'm moving house!
[11:18:54] <Bo^Dick> those aluminium rod setups have bigger workspace though compared to the machine size
[11:20:15] <The-Ball> anonimasu, converted?
[11:20:26] <anonimasu> it was once
[11:20:47] <anonimasu> though I could sell it converted..
[11:20:51] <The-Ball> did you change the screws?
[11:21:00] <anonimasu> yes
[11:21:17] <The-Ball> to what kind, and how little backlash where you able to obtain?
[11:21:24] <anonimasu> ballscrews..
[11:21:26] <anonimasu> 0.02mm
[11:21:36] <The-Ball> rolled?
[11:21:38] <anonimasu> shitty :/ though that's without anti backslash nuts..
[11:21:46] <anonimasu> no, but I cheaped out on the nuts
[11:22:00] <anonimasu> skf sells "backslash eleminated" nuts..
[11:22:31] <The-Ball> but they're not afraid of charging premium for them i bet
[11:22:36] <anonimasu> yep
[11:23:11] <anonimasu> I werent happy with the spindle ever.. :)
[11:23:36] <The-Ball> btw, i am sitting in the living room in front of the media senter and watching axis through VNC and listening to the mill from the garage, haha, got to love this
[11:23:37] <anonimasu> it's renovated..(new bearings) and stuff
[11:23:50] <anonimasu> so it should cut much better..
[11:23:59] <anonimasu> but I bought a better mill so it
[11:24:04] <anonimasu> it's not interesting anymore :)
[11:24:09] <The-Ball> what was wrong with the spindle?
[11:24:21] <anonimasu> flimsy..
[11:25:48] <anonimasu> I dont know, I got tired after all the mess related to it :)
[11:25:59] <anonimasu> never did cut that well, with the old bearings
[11:26:53] <anonimasu> so I grew tired of messing around trying to make it work, and I got a great deal on 2 other small machines
[11:27:12] <anonimasu> like ~750kg with about the same tablesize
[11:27:39] <The-Ball> ah, some day
[11:28:07] <anonimasu> I paid 2500eur for 2
[11:28:12] <anonimasu> in awesome condition :)
[11:29:13] <anonimasu> my conversion would have been easier if I had access to machines back then
[11:37:09] <The-Ball> ok, lesson learned, it is important to clear chips when milling deep circles
[11:38:07] <anonimasu> :/
[11:38:18] <anonimasu> did you break anything?
[11:47:08] <The-Ball> no, the end mill clogged up with alu and the servos stalled
[11:47:39] <The-Ball> but it's back in business doing it's thing
[11:49:12] <anonimasu> :)
[11:54:02] <The-Ball> arg, it happened again, maybe i should try a two flute end mill in stead of a four flute?
[11:54:21] <anonimasu> alu`?
[11:54:30] <anonimasu> not surprising that it's clogging :)
[11:54:35] <The-Ball> seems alu sticks to the flutes after a couple of circles
[11:54:45] <anonimasu> chip evacuation sucks with 4 flute ones..
[11:54:56] <anonimasu> with flood coolant it'd be much better
[12:01:14] <anonimasu> or a 2 flute cutter
[12:01:25] <anonimasu> The-Ball: are you running dry?
[12:01:45] <The-Ball> YES
[12:01:50] <archivist> ew
[12:01:53] <The-Ball> sorry need caps when talking to the servo controllers
[12:02:01] <anonimasu> ouch
[12:02:08] <anonimasu> got compressed air?
[12:02:39] <archivist> aly likes wet to stop sticking
[12:02:47] <anonimasu> yep
[12:02:52] <anonimasu> or special cutters..
[12:03:03] <anonimasu> or compressed air..
[12:03:09] <anonimasu> or just cutters with less flutes :)
[12:03:31] <archivist> is the machine upto climb milling as well
[12:06:43] <The-Ball> aha, two flute in and wd-40
[12:07:37] <The-Ball> yes, im climb milling the hole
[12:18:22] <The-Ball> ok, that works better, but i think i will have to give the neighbours a rest
[12:18:58] <anonimasu> compressed air ok :)
[12:19:05] <anonimasu> I'll be working late as hell today :/
[12:21:54] <The-Ball> I wish this was a proper house and not a town house
[12:22:54] <The-Ball> Time to change computers, let's see how the time laps video worked out
[12:30:52] <skunkworks> logger_emc: bookmark
[12:30:52] <skunkworks> Just this once .. here's the log:
http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2007-06-12.txt
[12:33:02] <alex_joni> skunkworks: nothing yet ;)
[12:33:40] <skunkworks> I was looking at The_Ball/ anonimasu conversation :)
[12:33:54] <alex_joni> like I said.. nothing interesting yet :P
[12:33:57] <skunkworks> ;)
[12:34:05] <alex_joni> j/k
[12:34:29] <skunkworks> morning alex
[12:34:48] <skunkworks> tried the telescope last night finally. Seems to work good.
[12:35:26] <skunkworks> needs to be 'tweeked' as the mount isn't really square to its self
[12:36:32] <alex_joni> nice :)
[12:36:36] <skunkworks> but it seemed to track ok.. saw the moons around jupiter and the rings around saturn. - oh - and a half phased venus
[12:39:37] <skunkworks> alex_joni: is there a lot of light polution where you are? or better yet - how far do you have to go to get a decent night sky
[12:42:50] <awallin> skunkworks: how big is your scope? I have been planning on getting a tracking mount myself, for wide-field photos
[12:43:39] <skunkworks> This is a small - 90mm scope.
[12:44:26] <skunkworks> 1250mm focal lenght
[12:44:30] <skunkworks> length
[12:45:22] <alex_joni> skunkworks: probably too much :)
[12:45:54] <awallin> the problem over here is that it doesn't get dark in the summer ;)

[12:49:07] <skunkworks> wow... How far north are you?
[12:50:40] <awallin> eh, only about 60 deg N, so it's a bit of an overstatement, but driving 7-800km north they do have 'days without nights'
[13:13:48] <alex_joni> bbl
[13:52:50] <The_Ball> Any of you guys in here that are present on the festcam?
[14:01:08] <skunkworks> umm - no one is there right now ;)
[14:01:28] <skunkworks> these are programers - they probably not up yet
[14:02:02] <The_Ball> ok, do you use gcam?
[14:02:06] <anonimasu> *yawn*
[14:03:17] <skunkworks> I do not.
[14:03:53] <archivist> I saw two ghosts on the fest cam a few minutes ago

[16:37:43] <CIA-2> 03jmkasunich 07TRUNK * 10emc2/src/hal/drivers/hal_ppmc.c: index pulse needs to reset entire 32 bit value, not just the 24 bit hardware counter
[16:39:51] <toastydeath> ffff
[16:45:28] <anonimasu> pfff
[16:45:31] <anonimasu> toasty!
[17:19:35] <CIA-2> 03jepler 07TRUNK * 10emc2/src/emc/kinematics/tp.c: make threading wait for index again
[17:22:25] <maddash> i've got two limit switches, one on either end of an axis, and i'm using one of these as a homingswitch. i've already set the HOME_IGNORE_LIMITS flag to YES, but emc refuses to home the axis after the initial search_vel phase, and it seems that it isn't ignoring the limits during homing. what am I doing wrong?
[17:25:43] <maddash> hm, does it matter whether I use the same signal for both homing and one of the limits in order for IGNORE_LIMITS to work?
[17:39:16] <jmkasunich> you'll want to route the signal from the parport pin (or whatever hardware) to both the limit and home pins on the motion controller
[17:41:43] <maddash> so I shouldn't be using two seperate signals?
[17:43:20] <maddash> ie, "newsig Y-neg-limit bit / net Y-neg-limit parport.0.pin-10-in => axis.1.neg-lim-sw-in / net Y-neg-limit parport.0.pin-10-in => axis.1.home-sw-in"
[17:43:22] <maddash> vs.
[17:43:37] <maddash> "newsig Y-neg-limit bit / newsig Y-home / net Y-neg-limit parport.0.pin-10-in => axis.1.neg-lim-sw-in / net Y-home parport.0.pin-10-in => axis.1.home-sw-in"
[17:44:00] <anonimasu> *yawn*
[17:49:53] <jepler> maddash: you can see what each of those do by executing them and then looking in 'halcmd show sig' to see what connections you end up with
[17:52:38] <maddash> heh, brb then.

[18:58:28] <CIA-2> 03jepler 07TRUNK * 10emc2/src/emc/task/emccanon.cc: fix G0 in feed-per-revolution mode
[19:01:57] <ds2> is there any reason why it would be bad to attach a solid tool to the side of a mill spindle and turn it into a CNC shaper?
[19:02:28] <anonimasu> yes..
[19:02:42] <ds2> ?
[19:02:49] <anonimasu> your mill spindle isnt very rigid..
[19:03:11] <anonimasu> rather most of the milling spindles arent made for that kind of load..
[19:03:11] <ds2> Oh... thought the forces on a shaper tool is similar to forces on an endmill?
[19:03:12] <anonimasu> :)
[19:03:21] <skunkworks> No - much more.
[19:03:27] <ds2> ah
[19:03:58] <skunkworks> the mill does most of the work
[19:04:06] <skunkworks> spinningness of it ;)
[19:04:40] <anonimasu> cutting..
[19:04:44] <anonimasu> the forces arent remotely the same
[19:04:53] <ds2> does that mean if I mount it 90deg such that the Z axis of the head is used as the shaper motion, it may be okay? (comparing a plunge/drill cut to a shaper)?
[19:05:01] <anonimasu> though I've seen broaching done.. on a cnc mill..
[19:05:55] <ds2> the background reasoning I am using is - mill heads are very similar to a lathe head; people use a lathe head to do little shaping jobs...therefore, I can do the same on a mill
[19:06:21] <anonimasu> _head_?
[19:06:24] <anonimasu> you mean spindle?
[19:06:41] <ds2> head and spindle are one assembly
[19:06:41] <anonimasu> yes they are similiar but look at what kind of bearing that sits in each one of them
[19:06:55] <anonimasu> that's where the big difference is..
[19:07:06] <ds2> for the smaller/cheap machines, they are the same (i.e. a Taig or a sherline and even the import mini mills)
[19:09:02] <anonimasu> im not going to argue about it really, I gave you a valid point.. take it if you like..
[19:09:51] <ds2> not disputing your point; there has to be a reason why this is not done often
[19:10:35] <anonimasu> because it places heap of load and wear on your spindle..
[19:10:53] <anonimasu> spindles = $$$$$
[19:10:54] <ds2> *nod*
[19:11:09] <anonimasu> loads of cash..
[19:11:13] <skunkworks> shapers are a lot heavier built. You will also have to remember to raise the head on the back stroke.. shapers have a clapper box that lets the tool get out of the way on the back stroke.
[19:11:30] <ds2> based on what you said; if I unbolt the spindle and replace it with a tool holder, is there any other reason?
[19:11:56] <anonimasu> if you arent worried about your machine either..
[19:12:00] <ds2> skunkworks: yes, that's the reason for the CNC portion.. have the controller lift the tool and any other needed things in software
[19:12:06] <anonimasu> the sturdiness issue..
[19:12:45] <ds2> Hmmm
[19:12:46] <jmkasunich> it comes down to how heavy the work is vs. how heavy the mill is
[19:12:50] <anonimasu> yep
[19:13:21] <anonimasu> and how much abuse you want to subject your mill to..
[19:13:32] <ds2> the main reason for a shaper that I can see is small keyways and cutting gears
[19:13:32] <jmkasunich> if you want to make a 2mm wide x 1mm deep keyway in the bore of an aluminum tooth-belt pulley once or twice, and have a bport sized mill, and take light cuts, go for it
[19:13:34] <archivist> poor drive screw/nut
[19:14:42] <skunkworks> we have a big shaper that would be really cool to mount a heafty spindle on it and make it cnc :)
[19:14:49] <anonimasu> ^_^
[19:15:10] <ds2> heh
[19:16:04] <archivist> I would not subject a nice leadscrew to shaping
[19:17:13] <jmkasunich> agreed in general
[19:17:37] <jmkasunich> if the cut is light enough tho, the forces will be no worse than drilling
[19:21:31] <jmkasunich> I wonder, which takes more force - a shaping cut 2mm wide x 0.02mm deep, or drilling a 12mm hole?
[19:21:32] <JymmmmEMC> If anyone uses IMAP, what client are you using?
[19:23:48] <archivist> jmkasunich, true drilling with standard drills do have high forces
[19:32:12] <JymmmmEMC> Has anyone seen/used newer systems/motherboards that have a paraport and work well with emc?
[19:32:43] <CIA-2> 03cradek 07TRUNK * 10emc2/src/emc/kinematics/tp.c: fix aborting during a feed-per-revolution move
[19:35:47] <ds2> maybe there is a scale/context bit that is missing here -- I was thinking of shapers that use at most a 3/8 by 3/8 HSS "lathe" bit.... not the ones that take a 1"x1" bit on a machine that looks like a giant truck engine
[19:35:54] <archivist> jmkasunich, I abused our drill press here today keyway slotting (only an 1/8" wide though)
[19:36:17] <JymmmmEMC> archivist: That musta been icky
[19:36:35] <archivist> on the limit 3 passes
[19:36:52] <JymmmmEMC> archivist: three passes to complete one slot?
[19:37:04] <archivist> yes, but using proper cutters for the job
[19:37:12] <JymmmmEMC> archivist: Ew
[19:37:32] <JymmmmEMC> archivist: wait... what material and how long?
[19:37:49] <skunkworks> archivist: a broach?
[19:38:35] <archivist> gear material about 10mm, dumont broach
[19:38:57] <JymmmmEMC> archivist: I'll assume not nylon gear then =)
[19:39:04] <archivist> steel
[19:39:22] <JymmmmEMC> ok, I take back what I said
[19:39:34] <archivist> Im glad I did not have to pay full price for the braoches
[19:39:40] <skunkworks> I like broaches. Wish I had a set.
[19:39:50] <skunkworks> I just use the ones here at work ;)
[19:40:34] <JymmmmEMC> * JymmmmEMC sends skunkworks a lovely broach, Victorian Era... Wear it with pride, you are woman, we hear you roar!
[19:40:36] <ds2> wish there was something like an adjustable width broach
[19:41:44] <skunkworks> JymmmmEMC: thank you - I am secure in my manhood to accept it.
[19:42:27] <anonimasu> JymmmmEMC: thunderbird
[19:42:38] <JymmmmEMC> skunkworks: LOL =)
[19:43:08] <JymmmmEMC> anonimasu: Yeah, that's the problem.... huge bugs in TB
[19:43:27] <JymmmmEMC> anonimasu: Trying to find an alternative, hopefully portable.
[19:44:13] <JymmmmEMC> anonimasu: but, thanks anyway.
[19:44:28] <anonimasu> :)
[19:44:46] <JymmmmEMC> anonimasu: are you using IMAP?
[19:45:05] <anonimasu> no
[19:45:05] <anonimasu> not atm
[19:45:20] <anonimasu> it was a too big mess to keep working with courier imapd :D
[19:45:42] <anonimasu> I use it for spam filtering
[19:45:55] <anonimasu> running dovecot and moving mails there..
[19:46:42] <JymmmmEMC> anonimasu: Ah, Well I serval IMAP accounts, and TB has authentication issues. Confirmed using an alternate IMAP client. bugzilla has mention of the bugs but all unconfirmed, so no telling when it'll ever get fixed.
[19:46:58] <anonimasu> :/
[19:47:12] <anonimasu> im working on a neat logo I can engrave on stuff
[19:47:28] <JymmmmEMC> anonimasu: url?
[19:47:46] <anonimasu> not yet
[19:48:08] <anonimasu> I just started
[19:49:06] <JymmmmEMC> anonimasu: ah, ok. I should do something like that, been thinking about it for years. The problem is I wait it to look good on paper, screen and engraved. kinda tough.
[19:49:22] <anonimasu> :)
[19:49:27] <anonimasu> I just want something simple that's mine :)
[19:49:38] <anonimasu> though it has to look special
[19:49:43] <anonimasu> and be easy enough to engrave on anything
[19:49:49] <JymmmmEMC> anonimasu: lineart?
[19:50:08] <anonimasu> no idea yet
[19:50:14] <anonimasu> playing with inkscape and my wacom tablet.
[19:50:39] <anonimasu> I probably want it a bit more advanced
[19:51:08] <JymmmmEMC> anonimasu: You would be surprised at how difficult lineart can really be if you take a close look....

[19:52:03] <anonimasu> :D
[19:52:13] <anonimasu> err, I draw to little to be good at it rather
[19:52:15] <JymmmmEMC> I mean eeeeeesh....

[20:57:36] <archivist> * archivist notes not to try and create a bad helix again
[20:57:56] <anonimasu> this the first time in a few years.
[20:58:14] <anonimasu> and right when I was happy with it.
[20:58:17] <archivist> yup normally rock solid
[21:07:52] <anonimasu> :)
[21:08:32] <archivist> tis my fave cad toy
[21:10:13] <archivist> I cant think in 2d since solidworks
[21:12:49] <anonimasu> :)
[21:12:53] <anonimasu> agreed
[21:25:53] <anonimasu> hm
[21:36:00] <CIA-2> 03jmkasunich 07TRUNK * 10emc2/src/hal/classicladder/classicladder_gtk.c: release shared memory before calling hal_exit(), not after
[21:56:13] <anonimasu> now the big question is how do I actually make a toolpath off this

[22:27:52] <anonimasu> hm
[22:29:04] <anonimasu> can anyone preview some gcode for me?
[22:32:52] <anonimasu> http://imagebin.org/8962
[22:33:05] <anonimasu> still needs a bit of tweaking
[22:34:53] <anonimasu> and some continents in the globe..
[22:43:42] <anonimasu> ah
[22:43:46] <anonimasu> now I know how to engrave it..
[22:43:53] <anonimasu> sheetcam should make a nice toolpath of it..
[22:54:00] <ds2> tried DXF -> ACEconverter?
[22:56:36] <anonimasu> no
[22:56:54] <anonimasu> what does it do and how does it work?
[23:03:43] <JymmmmEMC> http://www.dakeng.com/ace.html
[23:04:23] <anonimasu> does it work well with emc?
[23:04:27] <JymmmmEMC> anonimasu: you are drawing in inkscape ?
[23:04:43] <anonimasu> no
[23:04:53] <JymmmmEMC> what?
[23:04:55] <anonimasu> I used solidworks..
[23:04:58] <JymmmmEMC> ah
[23:05:11] <JymmmmEMC> are you outputting to 2d DXF?
[23:05:12] <anonimasu> but it needs lots of tweaking before im happy
[23:05:13] <anonimasu> yes
[23:05:38] <JymmmmEMC> and engraving, not 2.5D carving, right?
[23:05:47] <JymmmmEMC> basically line tracing (so to speak)?
[23:05:52] <anonimasu> yep
[23:06:14] <JymmmmEMC> anonimasu: you want me to convert whatever you have to gcode for you?
[23:07:11] <anonimasu> if you can that would rock :)
[23:07:31] <anonimasu> can you take solidworks files?
[23:07:33] <anonimasu> or do you want dxf?
[23:08:36] <JymmmmEMC> anonimasu: Ok, this is what I need... the drawing in DXF format, the w L h of the material. If you want Z0 to be TOM or BOM, what tool and it's specifics.
[23:09:01] <anonimasu> the tool is a 90 deg V bit
[23:09:26] <JymmmmEMC> what size? what RPM (if applicable), feed rate?
[23:09:42] <anonimasu> 2000 rpm 50mm/min
[23:09:55] <anonimasu> I have no idea about cutting data, but better play it safe..
[23:10:06] <JymmmmEMC> what size v-bit? Does it have a flat on the end of it?
[23:10:11] <anonimasu> no
[23:10:17] <JymmmmEMC> what size?
[23:10:22] <anonimasu> 6mm
[23:11:51] <JymmmmEMC> Oh, what depth do you want to engrave to?
[23:12:06] <anonimasu> I dont know really..
[23:12:05] <anonimasu> :D
[23:12:16] <JymmmmEMC> how thick a material?
[23:12:23] <anonimasu> I dont know..
[23:12:27] <anonimasu> it'll be on random stuff..
[23:12:32] <anonimasu> 0.1mm perhaps
[23:13:01] <JymmmmEMC> you are using a 1/4" v-bit??? Is this an engraving tool?
[23:13:16] <anonimasu> I have no idea
[23:13:22] <anonimasu> it's a random tool I found in the draer..
[23:13:24] <anonimasu> drawe
[23:13:25] <anonimasu> r
[23:13:29] <JymmmmEMC> heh
[23:13:31] <anonimasu> :)
[23:13:39] <anonimasu> I think it is
[23:13:41] <JymmmmEMC> hmmm, ok. got a pic of it?
[23:13:45] <anonimasu> no
[23:13:54] <anonimasu> it's a ----------->
[23:14:05] <JymmmmEMC> two flute?
[23:14:08] <anonimasu> yes
[23:14:13] <anonimasu> and it's made of carbide
[23:14:45] <JymmmmEMC> ok, I'll see what I can do. what size do you want the final result to be?
[23:14:54] <JymmmmEMC> and I don't know metric
[23:15:07] <anonimasu> googling
[23:15:13] <anonimasu> 20mm
[23:15:14] <JymmmmEMC> it'll convert it, but just so I'm sure.
[23:15:30] <JymmmmEMC> ok, so about 3/4"
[23:15:37] <JymmmmEMC> height or width?
[23:16:00] <anonimasu> 25.4 = 1"
[23:16:23] <JymmmmEMC> 20 millimeters = 0.787401575 in but is that the height or the width?
[23:16:28] <anonimasu> that's the width
[23:16:32] <JymmmmEMC> ok
[23:17:03] <JymmmmEMC> anonimasu: Ok, I usually make X0Y0 the bottom, left corner. is that okey with you?
[23:17:31] <anonimasu> if you can make it centered
[23:17:44] <anonimasu> it's easier to place right where you want it
[23:17:49] <anonimasu> I'll mail you the dxf
[23:19:21] <JymmmmEMC> Right, but I find that if you know the starting point, you can just measure up and right to know the whole area. If you make X0Y0, you have to half the width/height to make sure you don't go off the edge or out of a boundry (but to each his own).
[23:19:40] <JymmmmEMC> X0Y0 center, you...
[23:20:20] <JymmmmEMC> anyhow... nothing in stone (yet =)
[23:20:32] <anonimasu> mail's sent
[23:20:39] <anonimasu> dont worry about it place it where it's the easiest :)
[23:21:03] <JymmmmEMC> ok, Z0 TOM or BOM ?
[23:21:19] <JymmmmEMC> I do top, personally.
[23:23:44] <JymmmmEMC> heh, I always forget that DXF are in plain text.....pretty cool =)
[23:24:35] <anonimasu> tom/bom?
[23:24:48] <anonimasu> top of material
[23:24:50] <anonimasu> ..
[23:24:51] <JymmmmEMC> Top of Material / Bottom of material
[23:24:51] <anonimasu> :)
[23:25:34] <JymmmmEMC> is that a sunset with a tree?
[23:27:01] <anonimasu> no
[23:27:17] <anonimasu> the circle should be a earth
[23:27:20] <anonimasu> with some continents and stuff
[23:37:21] <anonimasu> :)
[23:37:27] <anonimasu> I'm going to go to bed
[23:37:31] <anonimasu> it's 01:36
