[00:00:28] <GammaX-Shop> ssi: yeah im in the process of that now...
[00:00:56] -!- Nick001-Shop has quit [Remote host closed the connection]
[00:01:11] <ssi> but that doesn't have anything to do with velocity/accel
[00:02:07] <GammaX-Shop> ssi: 2 problems.
[00:02:25] <GammaX-Shop> trying to fig our perfect vel accell and 2nd is my pitch must be off
[00:03:38] <ssi> get the pitch right first
[00:03:41] <ssi> set vel/accel low
[00:03:47] <ssi> 1ips, 2i/s/s
[00:04:19] <GammaX-Shop> the pitch is killing me. idk how its messed up at 5...
[00:04:39] <GammaX-Shop> motor steps per rev is 200... 1.8degree motor...
[00:05:10] <ssi> mhaberler: just sent you ssh key details
[00:05:17] <GammaX-Shop> i and i set the pitch to 5 as I put a caliper on there and 5 revolutions brings me to an inch
[00:05:21] <mhaberler> ah, good
[00:05:40] <ssi> 200 steps per rev, 5 revs per inch, is 1000 steps per inch
[00:05:45] <ssi> times your microstepping gives you pps
[00:05:51] <ssi> er, pulses per inch
[00:06:05] <ssi> mhaberler: I need to get to where I can build linuxcnc on the beagle
[00:06:18] <ssi> you said --with-threads=posix --enable-drivers right?
[00:06:19] <mhaberler> oh
[00:06:27] -!- Valen [[email protected]] has joined #linuxcnc
[00:06:40] <mhaberler> using 3.8 vanilla, yes
[00:06:59] <mhaberler> add --with-platform=bb
[00:07:32] <mhaberler> it wont compile hal_gpio.c because thats rpi, but you'll find that easily in the Submakefile
[00:08:12] <ssi> thats fine
[00:08:20] <ssi> I was planning on actually starting with a hal_bb_gpio for now
[00:08:21] <GammaX-Shop> fixed it
[00:08:28] <ssi> and eventually we can merge them and make it autodetect based on platform
[00:08:29] <ssi> or whatever
[00:08:47] <GammaX-Shop> might need MICRO adjustments in terms or making pitch 10.008 or something.
[00:09:12] <ssi> GammaX-Shop: once you have everything running well, jog across the whole table
[00:09:13] <ssi> 30" or so
[00:09:17] <ssi> and measure your actual vs expected
[00:09:22] <ssi> actually you probably can't measure 30" accurately
[00:09:28] <ssi> jog the full distance of what you can measure accurately
[00:09:39] <ssi> 1" for an indicator or whatever
[00:10:43] <GammaX-Shop> i can say run 20 inches from one side and check the number values attached to the turning handle to see how far off it is?
[00:10:52] <ssi> sure
[00:11:07] <ssi> btw gamma, I bought an optiplex 320 today at microcenter for $129
[00:11:16] <ssi> so I can throw that lenovo piece of shit out the window :D
[00:13:02] <GammaX-Shop> you said youd ship me it for free! hahaha
[00:13:23] <ssi> shipping will cost you more than buying one locally :P
[00:18:05] <GammaX-Shop> is it core 2 duo mb?
[00:18:37] <ssi> dunno
[00:18:47] <ssi> it's a lenovo 8808-94U

[00:27:31] <GammaX-Shop> ssi: when it says max acell in / s2 does that mean s squared?
[00:32:38] <ssi> inches per second per second
[00:32:54] <ssi> yes, s squared
[00:34:42] -!- adb has quit [Ping timeout: 256 seconds]
[00:34:54] <GammaX-Shop> ok
[00:34:56] <GammaX-Shop> gotcha thanks
[00:35:36] <GammaX-Shop> gonna be fun setting up modbus tomorow

[01:35:38] <ssi> I guess I get to do something fun like write a hal/ini configuration from scratch
[01:35:41] <ssi> weeee
[01:35:49] <PetefromTn> hehe..
[01:36:38] -!- hdokes has quit [Ping timeout: 252 seconds]
[01:38:37] <andypugh> I wouldn't suggest doing the INI from scratch, it's easier to start wth a close-enough sample config.
[01:38:47] <PetefromTn> Hadta buy a new refridgerator today YIPPEE!!
[01:39:10] <andypugh> HAL from scratch is easier, but even then starting with a sample config is likely to save some time.
[01:40:01] <ssi> yea I'll probably start from a sample
[01:40:10] <ssi> do you know offhand if any of the sample configs have a slaved stepper axis?
[01:40:21] <ssi> this is for my plasma table, and the gantry X axis has two slaved motors
[01:41:10] <andypugh> sim/stepper/ganrty
[01:41:15] <ssi> cool thanks
[01:41:35] <andypugh> And on that note, goodnight all.

[02:06:04] <ssi> haha latency numbers on the bbb are ridiculous
[02:06:16] <ssi> 3.3ms
[02:06:35] <ssi> I guess not surprising with a vanilla kernel :)
[02:16:11] <r00t4rd3d> bbb?
[02:16:27] <ssi> beaglebone black
[02:18:16] <skunkworks> did we get a beaglebone black xenomi kernel yet?
[02:18:20] <tjb1> r00t4rd3d?
[02:18:25] <r00t4rd3d> ?
[02:18:38] <ssi> skunkworks: mhaberler is working on it... he thinks it'll be soon
[02:18:51] <tjb1> you making your mill wider or did you just order a huge extrusion?
[02:18:57] <skunkworks> neat -- I have not been following the mailing list that close
[02:19:04] <ssi> I'm working on a general gpio driver now
[02:19:05] <r00t4rd3d> wider and longer
[02:20:01] <tjb1> so basically rebuilding the whole thing?
[02:20:03] <r00t4rd3d> 2x4
[02:20:09] <r00t4rd3d> yeagh
[02:22:54] <tjb1> add a print head

[02:41:49] <PetefromTn> yeah wut?
[02:41:53] <ssi> yeah!
[02:42:10] <PetefromTn> my browser sometimes does not seem to lock on until I do that..
[02:42:41] <PetefromTn> just finished cleaning the sight window glass for my coolant troughs.

[02:57:26] <ssi> any developers on that know what magic words I have to say to get my new hal driver to start being built by the make system? :P
[02:58:54] <Valen> perhaps look in the make file?
[02:59:20] <ssi> gosh I hadn't thought of that :P
[03:00:10] <Valen> glad i could help ;-P
[03:00:18] <ssi> aha I think I know what I have to do
[03:00:59] <PetefromTn> using Quassel

[03:13:30] <ssi> and these aren't exactly simple ones
[03:13:31] <ssi> :(
[03:18:09] <ssi> oh well, at least I have scotch
[03:28:31] <ssi> hm maybe it is working
[03:28:32] <ssi> heh
[03:30:53] <GammaX> Hey guys, Anyone use a hardinge varigrip?
[03:31:13] <GammaX> ssi everything workin now on your new pc?
[03:32:02] <ssi> yep!
[03:32:17] <ssi> not sure I'd be 100% thrilled with the latency numbers if I were software stepping
[03:32:21] <ssi> but I'm not, so nyah
[03:35:32] <tjb1> r00t4rd3d: https://www.dropbox.com/s/fdo76zf0qw3zmvc/2013-05-02%2018.00.27.jpg
[03:36:02] <GammaX> ssi what kinda 5c closer do you have on your system?
[03:36:09] <ssi> GammaX: stock
[03:36:30] <GammaX> theres 2 on ebay im thinkin about picking up if they dont get crazy
[03:36:33] <ssi> tjb1: mine: https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-frc1/577596_10100133843429202_1708616203_n.jpg
[03:36:40] -!- Roguish has quit [Remote host closed the connection]
[03:36:56] <tjb1> ssi: which is that?
[03:37:04] <ssi> my own variation of the rostock
[03:37:11] <tjb1> very nice looking
[03:37:14] <ssi> thx
[03:37:18] <tjb1> done yet?
[03:37:22] <ssi> nah
[03:37:32] <ssi> I haven't bothered to put a bed or extruder on it yet
[03:37:35] <ssi> it's been sitting in my cube at work
[03:37:39] <ssi> mostly a conversation piece :)
[03:37:46] <tjb1> I just upgraded mine to an airtripper
[03:37:47] <ssi> there's a second one of my design floating around
[03:37:51] <ssi> my friend charles bought it from me
[03:37:52] <ssi> and his runs
[03:38:04] <ssi> also I noticed the reel rollers in your photo
[03:38:10] <ssi> wonder if they're the original or my updated model :P
[03:38:14] <ssi> http://www.thingiverse.com/thing:26931
[03:38:15] <ssi> haha
[03:38:27] <tjb1> http://www.thingiverse.com/thing:21435
[03:39:00] <tjb1> ah, counterbores….I need that
[03:39:04] <ssi> hahah :D
[03:39:36] <tjb1> I am waiting on my new acrylic bed so I can go without a heated bed
[03:40:03] <ssi> charles is supposed to be waterjet cutting me an acrylic bed for mine
[03:40:06] <ssi> or aluminum maybe
[03:40:12] <ssi> he has a techshop near him, lucky bastard
[03:40:22] <tjb1> I am going to try to print direct on the acrylic with hairspray or oil in between
[03:41:13] <tjb1> I have corner warp issues with blue tape
[03:41:25] <tjb1> but I cant get the damn parts off when done....
[03:41:34] <ssi> I use PET tape
[03:41:38] <ssi> and I've been very happy with it
[03:41:40] <ssi> and heat
[03:41:42] <tjb1> PLA?
[03:41:46] <ssi> ABS mostly b
[03:41:49] <ssi> but PLA works too
[03:42:27] <tjb1> I am trying to get away from the heated bed
[03:42:38] <tjb1> takes so long and usually isnt much better
[03:43:07] <ssi> two tips
[03:43:10] <ssi> 1: flip it over
[03:43:16] <ssi> traces up, much more heat per unit power
[03:43:19] <ssi> 2: insulate the bottom
[03:43:29] <ssi> no sense heating the air under the machine
[03:43:35] <tjb1> I only have to go to 55 though :P
[03:43:42] <tjb1> I could never wait for it to hit 100
[03:43:49] <ssi> mine hits 110 in a couple minutes
[03:44:03] -!- dhoovie [[email protected]] has joined #linuxcnc
[03:45:22] <tjb1> You use like repetier or marlin?
[03:45:28] <ssi> marlin
[03:45:29] <tjb1> Or are you running linuxcnc
[03:45:32] <ssi> although I've been using repetier host
[03:45:47] <ssi> nah haven't tried using linuxcnc for printers yet
[03:45:50] <tjb1> I run repetier everything
[03:45:51] <ssi> more work than it's worth probably
[03:46:00] <ssi> on what hardware, ramps?
[03:46:04] <tjb1> The LCD move commands support delta movement
[03:46:05] <tjb1> ramps 1.4
[03:46:21] <ssi> if I get back into the delta, I might try to get your firmware
[03:46:26] <tjb1> Using an LCD with marlin and moving z only moved the z motor
[03:46:49] <ssi> I had johann's marlin patch working on the delta, and I had motion that worked ok
[03:47:07] <ssi> linuxcnc might be fun for the delta... is there a deltakins already written?
[03:47:48] <tjb1> The motion works just not when being controlled by an LCD
[03:47:57] <ssi> oh I see what you're saying
[03:48:14] <Valen> we might add a print head to our router
[03:48:28] <ssi> I want to add a spotdrill/engraving spindle to my plasma table

[05:33:43] <ssi> mhaberler: just the man I wanted to see!
[05:34:56] <mhaberler> what's up?
[05:35:19] <ssi> I started writing a skeleton for the hal driver, and I'm having a lot of trouble with the shared memory and registering pins with hal
[05:35:36] <mhaberler> ok, which trouble?
[05:35:48] <ssi> I have a port_data_t struct, and it contains an array of hal_bit_t pins
[05:35:54] <mhaberler> ok
[05:36:09] <ssi> hal_pin_bit_newf wants a hal_bit_t**
[05:36:17] <ssi> and I've had to jockey code around a bit to give it that
[05:36:23] <mhaberler> yes
[05:36:24] <ssi> and even in a way that I think should work, I still get:
[05:36:30] <ssi> HAL: ERROR: pin_new(bb_gpio.0.in-45) called with already-initialized memory
[05:37:17] <mhaberler> didnt you allocate the blockof memory where the pin pointers live with hal_malloc() ? (just lift the code from hal_parport.c)
[05:37:24] <ssi> yeah, I did
[05:37:44] <ssi> in fact, now I'm hal_malloc'ing the port_data structure, and it contains an array of bit pointers,
[05:37:53] <ssi> and I'm hal_mallocing each bit pointer individually
[05:38:03] <mhaberler> can you push it so I can reproduce?
[05:38:07] <ssi> sure
[05:39:04] <ssi> aw crap
[05:39:09] <ssi> I gave you the imcmahon user
[05:39:13] <ssi> but on the BBB I'm logged in as "linuxcnc"
[05:39:18] <ssi> wait I can fix that in .ssh config
[05:40:31] <ssi> ...maybe
[05:41:53] <ssi> ugh
[05:42:01] <ssi> I'm getting: fatal: remote error: access denied or repository not exported: /emc2-dev.git
[05:42:03] <mhaberler> just create a imcmahon user and push with that, probably easier
[05:42:08] <ssi> and it doesn't give me any clues as to the user it's using
[05:42:10] <ssi> ok I'll try it
[05:42:14] <mhaberler> oh, the git push uri
[05:42:30] <ssi> linuxcnc@arm:~/linuxcnc-dev$ git push --verbose
[05:42:30] <ssi> Pushing to git://git.mah.priv.at/emc2-dev.git
[05:42:32] <mhaberler> edit .git/config in the emc2 repo you're pushing
[05:42:44] <ssi> ok..
[05:43:27] <ssi> that did it
[05:43:38] <ssi> take a look at src/hal/drivers/hal_bb_gpio.c
[05:43:46] <mhaberler> ok
[05:44:01] <ssi> and like I said, I've monkeyed around with the structures a bit
[05:45:20] <ssi> OH
[05:45:22] <mhaberler> dont worry, but need to head over to the office, no bb here; it will be 15mins or so
[05:45:29] <ssi> my structure needs to have the pointers to the pin data
[05:45:33] <ssi> but hal will create the actual memory
[05:45:35] <ssi> I bet that's it
[05:45:51] <mhaberler> yeah, its very confusing initially with pins
[05:46:14] <ssi> yeah I think that did it

[05:47:13] <ssi> ok you go to the office, I'm going to BED
[05:47:17] <ssi> that's a good note to end on
[05:47:18] <mhaberler> I thought about collisions a bit (say pru)
[05:47:23] <ssi> yea?
[05:47:23] <mhaberler> I have a simple solution
[05:48:22] <mhaberler> we use a shared bitmap which is in initialized data and an exported symbol (actually two, the bitmap and size)
[05:48:26] <ssi> haha I have to fix my user info in git on the bbb
[05:48:41] <mhaberler> it has bits set to 1 for system-type pins (eg etc)
[05:49:12] <mhaberler> every hal driver needs to check the pins it uses against the bitmap, and may do so only if bit for that pin is 0
[05:49:30] <mhaberler> if she succeeds, set bit of that pin to 1
[05:49:38] <mhaberler> I'll do a prototype
[05:49:39] <ssi> that makes sense
[05:50:14] <mhaberler> however we'll switch your code to a development branch, say bb-hal-gpio
[05:51:00] <ssi> that would make me happy
[05:51:02] <mhaberler> jeesh, I really need to port that bitmap library
[05:51:19] <ssi> I dunno if you can fix the usernames on those last three commits or not
[05:51:28] <ssi> if not, I guess Joe Chipcutter will have a spot in the credits ;)
[05:51:44] <mhaberler> we'll divine the author
[05:51:49] <ssi> hahah
[05:52:54] <mhaberler> anyway, switch branches, push again, and I'll reset the arm335x-hal-pru-module branch to where it was so we dont trample in Charles' garden
[05:52:59] <ssi> ok
[05:53:31] <mhaberler> all these nice swamp flowers ;)
[05:53:49] <ssi> walk me through this so I do it right
[05:53:55] <ssi> git branching isn't my strong suit :/
[05:54:03] <mhaberler> git branch bb-hal-gpio
[05:54:07] <mhaberler> git checkout bb-hal-gpio
[05:54:28] <mhaberler> git push <repo> bb-hal-gpio (repo is likely 'origin')
[05:54:55] <mhaberler> it will come, it is a bit steep to start with, yes
[05:55:14] <mhaberler> perfect, worked fine
[05:55:34] <ssi> ok
[05:55:40] <ssi> so this branch already has the commits I made to the other?
[05:56:04] <ssi> yeah I guess it does
[05:56:30] <mhaberler> not anymore, I just pruned them
[05:56:43] <ssi> pruned them from bb-hal-gpio as well?
[05:56:47] <mhaberler> no
[05:56:50] <ssi> ok
[05:56:58] <mhaberler> you have your private sandbox now ;)
[05:57:07] <ssi> love it
[05:57:36] <mhaberler> dont worry about what's being pushed now, that can be cleaned up eventually before merging
[05:57:37] <ssi> so does it make sense that the pin names in hal reflect the physical pins on the device?
[05:57:54] <ssi> and if they can't be claimed, they simply won't exist?
[05:57:55] <mhaberler> I think so, confusion reduction
[05:58:15] <ssi> I was helping a guy in #beagle earlier who wanted to deal with GPIO in C
[05:58:21] <mhaberler> I would think the driver should either give a warning or fail
[05:58:22] <ssi> and he was going crazy cause nothing would work, including my code
[05:58:26] <mhaberler> aja
[05:58:30] <mhaberler> pinmux..
[05:58:31] <ssi> and it turns out he thought GPIO1_28 was P8, pin 28
[05:58:46] <ssi> so yes, there's a lot of room for confusion
[05:58:50] <mhaberler> yeah, thats standard
[05:59:01] <mhaberler> no, use header pin names, that's the way to go
[05:59:12] <mhaberler> port pins.. reverse engineering hell
[05:59:15] <ssi> yep
[05:59:32] <ssi> and it's terrible, because there's header pins, port pins, package ball pins
[05:59:39] <ssi> the mode0 name for a given pin
[05:59:43] <ssi> on and on
[06:00:09] <mhaberler> right… but old Joe most likely figures header pins and gets stuck with any other naming scheme
[06:00:32] <ssi> so the other thing I'm not sure about is if pin direction should be defined at driver load time or runtime a la mesa
[06:00:50] <mhaberler> let me see the mesa manpage
[06:01:34] <ssi> hostmot2
[06:01:36] <ssi> gpio section
[06:01:38] <ssi> is_output
[06:02:05] <ssi> I imagine he's registering the pins in hal as IO
[06:02:20] <ssi> and then just treating them differently in read_port/write_port depending on the parameter setting
[06:02:53] <mhaberler> maybe you want to read the section in the manual about canonical pin naming
[06:03:09] <ssi> which manual is that
[06:03:15] <mhaberler> let me see
[06:03:17] <ssi> hal manual I assume
[06:03:40] <mhaberler> http://www.linuxcnc.org/docs/html/hal/canonical-devices.html
[06:04:57] <mhaberler> personally I dont see much use for runtime direction changing, and it might be hairy
[06:05:03] <ssi> ok
[06:05:21] <ssi> so then configuration bitmasks
[06:05:24] <ssi> input mask, output mask
[06:06:12] <mhaberler> yes, maybe variations for pullup. pulldown, floating
[06:06:32] <ssi> that's where my original suggestion came from
[06:06:40] <ssi> charstring, -, O, I, U, D
[06:06:53] <ssi> for "not connected", output, floating, pullup, pulldown
[06:07:04] <mhaberler> sorry, please dont - this string sausage will be the perfect error trap
[06:07:07] <ssi> right
[06:07:26] <ssi> I just am having a hard time finding the middle ground between that and andy's runtime parameter suggestion
[06:07:43] <mhaberler> make sure you break the rules in time ;)
[06:08:03] <ssi> what about a mask for input, a mask for output, and then have pullups be runtime configured?
[06:08:27] <mhaberler> kiss...
[06:08:28] <ssi> (I haven't been successful in making a pin anything but a pullup so far, so maybe that's moot)
[06:09:09] <mhaberler> (philosophical) re runtime changes in hal: hal supports too much of this to start with
[06:09:33] <mhaberler> we eventually need a clear HAL session concept where a HAL setup gets committed and frozen
[06:09:57] <mhaberler> so components dont have to chase possible halcmd changes on the fly, which can be hairy
[06:10:11] <ssi> makes sense,
[06:10:18] <ssi> but from a pure configuration language perspective
[06:10:20] <mhaberler> in some cases that translates into runtime overhead
[06:10:40] <ssi> foo.pin-01.pullup = TRUE on fifteen lines is easier to deal with than a mask string
[06:11:22] <mhaberler> fifteen lines.. dont get it; the config must be a loadrt hal_gpio param(s)
[06:11:31] <mhaberler> oh I see
[06:11:39] <mhaberler> yeah sure
[06:12:00] <mhaberler> lots of useless pins - swamps namespace
[06:12:16] <ssi> another alternative might be to take a "firmware" approach
[06:12:35] <ssi> where there's a file that defines pinmuxing, and filename is passed in on config line
[06:13:26] -!- jfire has quit [Quit: Leaving.]
[06:13:36] <mhaberler> we currently dont use that and not sure if it makes sense to create an extra external file dependency if halcmd proper suffices
[06:13:49] <ssi> ok
[06:13:57] -!- kmrhb has quit [Ping timeout: 256 seconds]
[06:14:32] <ssi> again, drawing ideas from the mesa drivers... they sort of work that way with fpga firmwares
[06:14:38] <mhaberler> I have been looking into a flex scanner for the config strings; just use the simplest method for now to get it to work and we'll polish later
[06:14:43] <mhaberler> right
[06:14:49] <ssi> although I don't know the specifics of how hm2 configures pins based on the firmware you choose
[06:15:18] <ssi> yea for right now I'm going to do either a pair of mask strings or a pair of comma separated pin number strings
[06:15:20] <mhaberler> I think the firmware and the firmware params define the pin usage
[06:15:21] <mhaberler> and its
[06:15:21] <ssi> the latter might be better initially
[06:15:29] <mhaberler> read back from the setup info
[06:15:36] <ssi> cause I think we're more likely to have fewer than half of the pins on a header in use
[06:15:39] <ssi> at least as GPIO
[06:15:40] <mhaberler> that case we dont really have
[06:16:11] <ssi> so something like input=1,2,3,4,10,15 output=5,6,8,15 might be better than input=XXXX------X----X etc
[06:16:26] <mhaberler> absolutely, much less error potential
[06:16:42] <mhaberler> no more column counting like in COBOL or FORTRAN ;)
[06:16:45] <ssi> :)
[06:17:20] <ssi> what do you think about adding 100 or 200 to the pin number for P8/P9?
[06:17:28] <ssi> so P8, pin 1 would be 101, P9 pin 1 would be 201
[06:18:21] <mhaberler> use it for now; I'll implant a decent scanner eventually which can more easily work with board-specific pin naming
[06:18:26] <ssi> ok
[06:18:31] <mhaberler> so eventually we'll have input=p8-2 etc
[06:18:51] <ssi> that works
[06:18:59] <ssi> and I'll just run with all inputs are pullup for now
[06:19:04] <ssi> since I can't seem to make it do otherwise anyway
[06:19:07] <mhaberler> that was due anyway.. everybody starts up massaging strings by char inspection ca 1969 style..
[06:19:31] <mhaberler> that'd be fine
[06:19:54] <ssi> ok well, I'll get some sleep, and hopefully tomorrow I'll be blinking leds in halcmd :)
[06:19:59] <mhaberler> sure
[06:20:03] <ssi> thanks for the help
[06:20:13] <mhaberler> btw whats the case with the onboard leds
[06:20:22] <ssi> what about them?
[06:20:24] <ssi> they're on GPIOs
[06:20:28] <mhaberler> you detect those and disable kernel fiddling with same?
[06:20:28] <ssi> but I'm not sure if they're shared with pins
[06:20:29] <ssi> I think not
[06:20:38] <mhaberler> ok, random detail
[06:20:51] <ssi> well, what I did for now is build a kernel with the gpio_leds driver modularized
[06:21:01] <mhaberler> aja, I remember
[06:21:03] <ssi> I don't yet know how to disable the leds driver
[06:21:06] -!- Nick001 has quit [Ping timeout: 264 seconds]
[06:21:20] <mhaberler> blacklist in /etc/modules or somesuch
[06:21:28] <ssi> oh I don't mean the module
[06:21:33] <ssi> I easily can not load the module
[06:21:43] <ssi> I'm not sure if there's a way you can tell the driver to release the gpios via sysfs or someting
[06:21:58] -!- holst [[email protected]] has joined #linuxcnc
[06:22:01] <mhaberler> you mean stop kernel wiggling the leds.. there is a way, I just dont remember
[06:22:04] <ssi> yeah
[06:22:09] <ssi> I'll look into it, but it's not a high priority
[06:22:21] <ssi> also, do we still think that the way to tell the kernel we're using pins is sysfs?
[06:22:31] <ssi> or is it feasible to call gpio_request directly?
[06:22:39] <mhaberler> best bet: eewiki - Robert Nelson; bet #2 - #beagle (which is a tad unprofessional if I may say so..)
[06:23:12] <mhaberler> gpio_request() is a userland function, or kernel? (loosing track...)
[06:23:18] <ssi> I think it's kernelspace
[06:23:25] <mhaberler> then no - sysfs
[06:23:28] <ssi> ok
[06:23:33] <mhaberler> we dont want kernel code if we can avoid it
[06:23:54] <ssi> what's the penalty?
[06:24:09] <mhaberler> sysfs walking at startup
[06:24:18] -!- largecheesepuff has quit [Ping timeout: 252 seconds]
[06:24:41] <ssi> I mean what is the downside to having kernel code in our drivers?
[06:24:51] <mhaberler> well to start with, it's harder to debug, and the whole point of the userland threads effort was to get rid of kernel code dependencies
[06:25:00] <ssi> gotcha
[06:25:04] <ssi> oh that raises another question
[06:25:19] <ssi> is it straightforward to debug these drivers loading with gdb or something?
[06:25:24] <ssi> I wasn't really sure how to go about it
[06:25:25] <mhaberler> absolutely
[06:25:40] <mhaberler> but trapping the call isnt totally obvious, you do it like so
[06:25:51] -!- Nick001 [[email protected]] has joined #linuxcnc
[06:25:55] <mhaberler> start realtime, this will give a pid for rtapi_app
[06:26:05] -!- largecheesepuff [[email protected]] has joined #linuxcnc
[06:26:11] <mhaberler> now 'gdb -p <pid of rtapi_app>'
[06:26:18] <mhaberler> b rtapi_app_main
[06:26:20] <mhaberler> continue
[06:26:27] <ssi> start realtime... halrun will do that?
[06:26:40] <mhaberler> then loadrt the driver, peng, breakpoint in rtapi_app_main
[06:26:46] <mhaberler> no, shellscript
[06:26:53] <mhaberler> 'realtime start'
[06:27:08] <ssi> ok
[06:27:19] <ssi> returns with no output,
[06:27:22] <mhaberler> need to check what's needed in this branch; it could be it isnt yet
[06:27:24] <ssi> and I don't see a process either rtapi or realtime
[06:27:30] <ssi> oh I'm still on vanilla kernel
[06:27:33] <ssi> maybe that screws me up?
[06:27:37] <mhaberler> doesnt matter
[06:27:54] <mhaberler> no rtapi_app might start only after first module load in that branch
[06:28:00] <mhaberler> so halcmd load or2 or so
[06:28:06] <mhaberler> then you'd have the process

[06:28:23] <mhaberler> then attach gdb

[06:28:28] <mhaberler> yes

[06:29:03] <mhaberler> in a different window do 'halcmd loadrt hal_gpio'
[06:29:12] <ssi> yep got it
[06:29:13] <mhaberler> that should break you in the module init routine
[06:29:51] <mhaberler> (that used to be kernel-only with the rtai flavor.. extra penalty, printk and all)
[06:30:33] <ssi> are the x86 builds movin away from rtai to xenomai as well?
[06:31:03] <mhaberler> no, dont think so - we'll have x86 builds which run on all of them (rtai, xenomai, rtpreempt)
[06:31:08] <ssi> gotcha
[06:31:53] <mhaberler> there's work in progress to support all rtos flavors with a single linuxcnc build so no more reinstall needed, just boot different kernel and go
[06:32:37] <ssi> looks like what you get if you just hit the website and download first available image is rtia
[06:32:42] <ssi> that's what's on the machine I just built
[06:32:50] <mhaberler> yes
[06:33:09] <mhaberler> it used to be the only game in town and in terms of pre-built packages it still is

[14:19:26] <andypugh> Should be simple then.
[14:20:43] <andypugh> How likely is it that the distance from the top of my table to the leadscrew is 3 11/32" ? Do you Imperialists use such not-round numbers?
[14:20:46] <R2E4> I figured that portion would work. The issues would be everything else..... The logic, there is alot of connections between the seicos BS controller and the drives.....
[14:21:22] <andypugh> Well, you only asked about the drives...
[14:21:26] <jdh> andypugh: who designed it?
[14:21:41] <andypugh> Harrison, Heckmondwike in about 1970.

[15:53:45] <chopper791> Have a couple questions about the thcud.comp file. The first question- There are the following pins in the comp file, pin in float z_pos_in "Z Motor Position Command in from axis.n.motor-pos-cmd";
[15:53:46] <chopper791> // Output Pins
[15:53:46] <chopper791> pin out float z_pos_out "Z Motor Position Command Out";
[15:53:46] <chopper791> pin out float z_fb_out "Z Position Feedback to Axis";
[15:53:46] <chopper791> Do those need to be in the HAL file for them to work?
[15:54:24] -!- Bojangles [[email protected]] has joined #linuxcnc
[15:55:20] <JT-Shop> yep
[15:59:47] <chopper791> Ok- So I need to place them in the Z axis(Joint 2) section to allow axis.2.pos-cmd to go to z_pos_in then, so on and so on?
[16:01:31] <chopper791> I thought I needed to do that, but when I do I get an error when launching stating that pin z_pos_in does not exist.

[16:30:59] <chopper791> jt- yeah my spelling has some errors sometimes.
[16:31:11] <JT-Shop> comment out any offending pins till it loads then use Show Hal Configuration to see the names of the pins
[16:31:59] <pcw_home> thats probably because linuxcnc was not running
[16:32:19] <chopper791> JT & pcw - that worked.
[16:33:04] <chopper791> sthe pins show it a z-pos-in and not z_pos_in as shown in the comp
[16:33:06] <pcw_home> you can re-direct the output of halcmd show pin to a file as a donor file when editing the hal file
[16:33:37] <JT-Shop> that is comp magic working on you
[16:35:39] <JT-Shop> also in a terminal when LinuxCNC is not running you can do halrun, loadrt thcud, show pin, the comma indicating press the enter key
[16:36:22] <chopper791> got ya
[16:36:48] <chopper791> So I ned to change the underscores to dash and then it should be fine I would guess?
[16:37:48] <chopper791> or maybe not as all of the pins in the comp are under scores and not dashes, but the terminal shows dashes.
[16:38:11] <chopper791> What is this comp magic you speak of JT?
[16:38:37] <chopper791> The ability to change dashes to underscores or was I not readignt he sarcasm correctly

[16:40:56] <chopper791> I can copy and paste them but to where?
[16:41:04] <pcw_home> if you load all the components and then do a a halcmd showpin > pins
[16:41:43] <pcw_home> you can open the pins file while you edit your hal file and copy/paste from it onto the hal file

[16:47:44] <pcw_home> its just a wrapper so we can send our normal register read/write commands over a serial/usb/Ethernet link
[16:47:55] <ssi> gotcha
[16:48:10] <ssi> I'm trying to divine how the 7i77 works to figure out what it'd take to run it on the beagle
[16:48:45] <ssi> I guess the 25 pin just carries several channels of sserial?
[16:48:52] <ssi> it seems like none of them are just straing input/output pins
[16:49:31] <pcw_home> Probably tough but possible
[16:49:33] <pcw_home> the beagle has multiple serial ports that can run up to 3.698 MB

[16:52:22] <JT-Shop> jdh: no G92 let me look at #5223
[16:52:22] <pcw_home> The PRU should be able to run effectively the same code that runs on the FPGAs processor
[16:52:24] <pcw_home> (this code hides the protocol timing and other complexities and presents a register interface to the HAL driver)

[17:05:20] <ssi> my basement has a half inch of water in it :/
[17:05:21] <generic_nick|2> pcw_home: figured out how to put the drive in velocity mode, works much better now, thanks.
[17:05:28] <pcw_home> Not sure what level of control is needed (setting up pin mux and GPIO)
[17:05:30] <pcw_home> but in any case if you wished to get along with other capes that likely use kernel drivers
[17:05:31] <pcw_home> you need something to say 'dont touch, we will use our own driver'
[17:05:44] <ssi> right
[17:05:47] <chopper791> I switched the _ to - in the HAL file and the errors are different now. The new error is 'thcud.z-pos-out' must not be the same as a pin. I would have to guess that I have this signal name in the wrong location or would it be caused from something else?
[17:05:54] <ssi> mhaberler and I have been talking about how to do that a lot lately
[17:05:58] <ssi> it's not an easy problem to solve
[17:06:28] <pcw_home> No, makes me like FPGAs more and more :-)
[17:06:29] <generic_nick|2> i had to uncheck a box in the software that allowed more options (like putting it in velocity mode)
[17:06:54] <pcw_home> Yeah velocity mode is usually much easier to tune
[17:06:59] <generic_nick|2> i have a tiny bit of p in linuxcnc and thats it
[17:07:07] -!- Bojangles [[email protected]] has joined #linuxcnc
[17:07:07] <generic_nick|2> like .05
[17:07:40] <pcw_home> velocity mode uses FF1 also for best performance
[17:07:51] <generic_nick|2> couldnt add any, it made it worse
[17:07:59] <andypugh> chopper791: You can't have a signal that has the same name as a pin. The first thing after the "net" command is always a signal name. You have wither forgotten to make up a signal name for the net, or you are trying to create a signal with the same name as a pin.
[17:08:08] <pcw_home> then you are not adding the right amount
[17:08:36] <generic_nick|2> i tried as little as .005 in ff1, it ferrored pretty quickly
[17:08:57] <generic_nick|2> it has the least amount of ferror with no ff1
[17:09:31] <pcw_home> I doubt if thats possible
[17:09:44] <chopper791> andy- I have thcud.z-pos-out going
[17:09:48] <chopper791> net zpos-cmd thcud.z-pos-in <= axis.2.motor-pos-cmd
[17:09:48] <chopper791> net thcud.z-pos-out => stepgen.2.position-cmd
[17:09:48] <chopper791> #net axis.2.motor-pos-fb <= thcud.z-fb-out
[17:10:06] <generic_nick|2> i checked it on the scope
[17:10:14] <ssi> net zpos-actual thcud.z-pos-out => stepgen.2.position-cmd
[17:10:17] <ssi> give it a signal name
[17:10:28] <generic_nick|2> but regardless, it's probably not perfect but it works good enough lol
[17:10:43] <IchGuckLive> chopper791: what thc is it
[17:10:47] <JT-Shop> somehow the G10 L10 P1 Z0.000 line is changing the G54 offset even though it is not ran
[17:10:49] <generic_nick|2> at least it has holding torque now!
[17:10:59] <pcw_home> if you have too little FF1 you will lag on a long fast move, with too much, you will lead
[17:11:03] <JT-Shop> opps G10 L20 P1 Z0.000
[17:11:38] <JT-Shop> generic_nick|2: now that your in velocity mode have you seen my velocity mode tuning tutorial
[17:11:39] <pcw_home> since a P of.05 works your scaling is such that FF1 may be very small

[17:18:09] <andypugh> I like to think as the signal as a wire colour. So it hints at, but does not define, the signal :-)

[17:19:43] <generic_nick|2> the touch screen doesnt work well when wet
[17:19:52] <IchGuckLive> chopper791: did you aply a servo tread to the thcud
[17:20:01] <JT-Shop> http://gnipsel.com/shop/bp1/bp1-01.xhtml
[17:20:07] <L84Supper> IchGuckLive: are there any hackerspaces in your area?
[17:20:22] <chopper791> ich-I have not since the thcud file did not show that was needed
[17:20:40] <IchGuckLive> so no interpreter feedback
[17:20:44] <generic_nick|2> JT-Shop: thats where i have mine now and it's covered in coolant and chips
[17:20:54] <IchGuckLive> (loadrt thcud) and add it to a thread (addf thcud servo-thread) chopper791
[17:21:02] <generic_nick|2> i run mass production on it with flood coolant so it makes a bit of a mess
[17:21:26] <JT-Shop> how do you manage to use coolant on a knee mill without making a huge mess in your shop?
[17:21:38] <generic_nick|2> i buit a box around the table
[17:21:46] <JT-Shop> got a photo?
[17:21:58] <generic_nick|2> not on this pc
[17:22:03] <generic_nick|2> ill snap one soon.
[17:22:07] <JT-Shop> ok
[17:22:29] <JT-Shop> you could build a lean to over the MPG

[18:04:14] <Tom_itx> jdh, what's your plunge feed?
[18:04:26] <Tom_itx> it should be at least half your regular feedrate
[18:04:46] <jdh> what's the correlation?
[18:06:06] <Tom_itx> it's just a good idea
[18:06:23] <jdh> but, it's not feeding when it's plunging?
[18:06:41] <jdh> plunge was set to 5ipm, feed to 15ipm, but I was only running about half that.
[18:06:49] <Tom_itx> my cam puts out a separate defineable plunge feed aside from the regular feedrate
[18:07:14] <Tom_itx> tool too long?
[18:08:03] <jdh> normal HSS 1/4" 2-flute end mill
[18:08:39] <Tom_itx> is it dull?
[18:09:09] <jdh> no. I've noticed it with other tooling also, also happens with my router, mainly 1/8" carbide in plastic
[18:09:15] <Tom_itx> i switched to carbide on my sherline since i don't have flood coolant on it
[18:09:21] <Tom_itx> seems to do better for me
[18:09:36] <Tom_itx> your z may have flex in it then
[18:09:43] <jdh> my spindle maxes at 3000rpm, carbide doesn't seem beneficial there for 6061
[18:09:48] <Tom_itx> or x and y aren't rigid enough
[18:10:21] <Tom_itx> you can always drill a pilot hole to plunge in
[18:13:48] <jdh> I assume if I put the pilot hole in the same place, it would have the same issue

[18:19:55] <Tom_itx> why?
[18:20:05] <Tom_itx> the endmill isn't really made for drilling
[18:20:34] <Tom_itx> if you drill a pilot hole and put the endmill down in it then move in x or y it shouldn't walk on you
[18:25:07] <jdh> just curious. I sometimes make the plunge position someplace that won't matter, but don't usually bother.
[18:31:10] <archivist> slot drill is the better form for plunge
[18:38:52] <Loetmichel> or move into the workpiece in a helix. works also

[19:18:02] <cradek> waah
[19:18:05] <PetefromTn> ssi: Thanks man. Honestly that picture really does it no justice. That is some serious flow coming out of there I was kinda worried I would not have adequate flow for chip evac with the factory pump but it surprised me. I may make a nice manifold to add some nozzles to bump up the pattern later but for now this is real nice.
[19:19:00] <cpresser_> a usb2dmx interface which uses the same protocol is also planned. i got the prototypes up an working.

[19:39:13] <PetefromTn> How many of you fellas are using pycam seriously? Is it generating good toolpaths for you?
[19:39:42] <andypugh> To be honest, it is far too slow on the useful contouring processes to be any real use.

[20:03:45] <frallzor> I´d say... no
[20:03:54] <r00t4rd3d> its how i do it

[22:49:20] <PetefromTn> Nice looking stuff. I am sure it is equally nicely priced.
[22:49:25] <Tom_itx> i forget the brand
[22:49:25] <Tom_itx> yup
[22:49:50] <Tom_itx> my friend has those at his shop and i must say it makes setups alot quicker
[22:50:54] <PetefromTn> apparently the six inch vise alone is $1500.00 +
[22:51:02] <Tom_itx> could be
[22:51:13] <Tom_itx> the average 6" single is around $6-800
[22:51:21] <Tom_itx> you can get them on sale usually
[22:51:36] <Tom_itx> since they're so common
[22:52:07] <Tom_itx> he had a couple dual but mostly 6 & 8" single kurt
[22:52:23] <PetefromTn> average where? I need to pickup a vise for the VMC now that it is running but I am a poor bastard now LOL
[22:52:36] <Tom_itx> see what travers has
[22:52:49] <PetefromTn> never bought from travers tool
[22:53:09] <Tom_itx> or mts

[22:54:26] <andypugh> I have a spare 8" Kurt double. When I say "spare" I mean "going rusty on the floor as I will never use it"
[22:54:39] * Tom_itx gasps
[22:54:52] <andypugh> Partly because it has no jaws. (Which is quite a drawback)
[22:54:57] <Tom_itx> andypugh, pack it in your carry on :)
[22:55:01] <PetefromTn> yeah but you are in jolly old england and it would cost more to ship probably than it costs to buy here LOL
[22:55:12] <ssi> jaws are available
[22:55:14] <andypugh> I can barely lift it.
[22:55:17] <ssi> tehy're not terribly cheap, but they're out there
[22:55:19] <Tom_itx> i bet
[22:55:21] <ssi> but yea a double 8 is a BIG vise
[22:55:27] <Tom_itx> the 8" single are heavy enough
[22:55:29] <ssi> mine's a double 4, and it's a good size for my 9x42
[22:55:31] <PetefromTn> That would be a sweet vise tho...
[22:55:47] <PetefromTn> I bet it weighs 200 lbs..
[22:55:59] <andypugh> Yes, quite. I can buy a much more suitable vice for my purposes for a lot less than a set of jaws for the Kurt.
[22:56:26] <PetefromTn> Hell I usually make my own sacrificial jaws for most everything anyways.
[22:57:16] <PetefromTn> never even seen an 8" double vise, how long is it?
[22:57:22] <Tom_itx> yup
[22:57:48] <andypugh> About 2'6"?
[22:57:53] <ssi> holy cow
[22:57:54] <ssi> hahah
[22:58:08] <andypugh> It looked smaller on the eBay advert.

[23:00:13] <ssi> whoa they went up
[23:00:17] <ssi> I'd buy the kurt for that money nm
[23:00:18] <ssi> ;p
[23:00:38] <ssi> I wish they made a 4" with the flat sides like that
[23:02:22] <andypugh> Looks like Abwood are no longer in the vice business.
[23:03:25] <generic_nick|2> dang it! i lost all my work offsets AGAIN!
[23:03:28] <PetefromTn> actually that glacern is not terrible and reasonable for a better quality vise...

[23:04:00] <generic_nick|2> anyone know why my work offsets dissapear if my machine shuts off due to a power loss?
[23:04:01] <PetefromTn> I am really gonna have to go cheaper than that to right now. My damn AC unit at home here is smoked so gotta ante up for that baby first....

[23:07:22] -!- stsydow has quit [Remote host closed the connection]
[23:07:48] <andypugh> generic_nick|2: The offsets are saved at shutdown. If you don't get a proper shutdown, then they don't get saved.
[23:08:21] <Tom_itx> no way to back up the file?
[23:08:30] <andypugh> Can I say that the problem is your power supply, not LinuxCNC?
[23:09:02] <generic_nick|2> andypugh: not the power supply when the whole house looses power
[23:09:04] <andypugh> But, if you do all the touch-off, then quit LinuxCNC, then re-open, that shpiuld save the offsets
[23:09:34] <andypugh> generic_nick|2: I think you might want to consider a small UPS, just for the PC.
[23:09:36] <generic_nick|2> andypugh: my offsets havent changed in years, why doesnt it just not delete the last ones it saved?
[23:09:47] <generic_nick|2> it changes it all to zero
[23:10:02] <andypugh> Ah, OK, if that is what is happening, I am at a loss to explain it.
[23:11:13] <generic_nick|2> yea, they all go to home position
[23:11:17] <andypugh> A PC-sized UPS is pretty cheap.. http://www.amazon.com/CyberPower-CP350SLG-Standby-350VA-Compact/dp/B004OR0V2C/ref=sr_1_7?ie=UTF8&qid=1367881826&sr=8-7&keywords=UPS
[23:12:29] <PetefromTn> yeah import...
[23:12:35] <generic_nick|2> the work offsets are saved to the var file, right?
[23:12:41] <andypugh> I don't know how long that would give you to exit and shutdown though.
[23:12:41] <PetefromTn> a 4" vise is not gonna cut it for me...
[23:13:24] <generic_nick|2> vices are cheap if you buy them used, i got a few kurt vices for $50-100
[23:13:45] <andypugh> I lack headroom in my machine, so I am looking at this sort of thing: http://www.ebay.co.uk/itm/2-pc-LIMITLESS-MILLING-VICE-WITH-6-JAWS-/370658211083?pt=LH_DefaultDomain_3&hash=item564cf3750b

[23:29:27] <andypugh> PetefromTn: The toolpath generation is really slow, with some of the algorithms. The Algorithms that are fast are slow to machine, too. Lots of travel to safe-Z and rapid to the opposite corner of the work, lots of cutting air. But it gets the job done.
[23:29:48] <andypugh> The probe is just a probe I got from eBay.
