[01:51:55] <tomp2> this month's circuit cellar has a usb based pulse generator, capable of 100nS pulses, 200nS periods ( and up ). what, in general would be needed to get this to work with hal?
[01:52:56] <tomp2> hmm, i'd only be telling it what to do, so I'm wondering about communiction to a usb device
[01:56:45] <jepler> tomp2: to control something that needs realtime -- like an X axis servo motor -- it's a substantial amount of work by someone with high understanding of both USB and realtime programming. emc doesn't yet support any realtime USB devices of any kind.
[01:57:49] <jepler> if it's to control something where non-realtime performance is acceptable -- like open-loop spindle control -- it would be a matter of a much easier to write userspace component
[01:59:00] <tomp2> jepler: i dont think i need realtime, something along the timing demands of a pump button ( not very critical timing wise ). but i admit I dontknow usb, i just saw the protocal was some ascii text and thought that'd be possible.
[02:00:16] <jepler> tomp2: some USB devices appear to the OS as serial ports -- this one could be of that type.
[02:00:38] <jepler> if so, the non-realtime driver would probably be under 50 lines of Python code or under 200 lines of C code
[02:01:55] <Skullworks-PGAB> Jepler: Do you know the line count of the encoders that are on those servo gearmotors you had on your etch-a-sketch?
[02:02:49] <jepler> tomp2: in your place, I'd want to start by getting any kind of linux program in c or python to talk to the device, then add the communication with HAL
[02:03:11] <jepler> you'd read the values from HAL, then format a message to send to the device, then wait a small length of time, then do it all over again
[02:04:07] <jepler> Skullworks-PGAB: my recollection is fuzzy, but I believe the encoders were 100 lines, the gearbox built in to the motors was 6:1, and I used x4 mode. This gave 2400 counts per revolution of the shaft.
[02:04:25] <tomp2> jepler: thanks, that sounds like what's needed. there's no feedback from this oscillator, just commands to it ( enable disabe ontime offtime )
[02:05:42] <Skullworks-PGAB> I picked up like 10 of those motors - the encoders are worth more than the motors - they have Agilent internals
[02:07:36] <Skullworks-PGAB> a real job to disassemble - but they can be used on more potent servos - just need a 3mm shaft to mount the disk on
[02:19:34] <distracted> cradek: That worked. I now have bare bones EMC2 with 2 parallel ports! Yahoo! (hope that's not copywrighted)
[02:36:14] <jepler> whee this is fun (needs java):
http://dan-ball.jp/en/javagame/dust/
[02:37:20] <jepler> for instance, make a C= shaped curve from "bloc", then put "dust" at the mouth and "gunpowder" in the middle
[02:37:27] <jepler> then set the whole thing off with a little "fire"
[02:40:04] <Skullworks-PGAB> carefull - talk like that will have Homeland security reading our logs

[10:41:49] <cnc_engineer> i get en error message "tkConfig.sh not found, trying tk.h and libs" when i apply "./configure" command, what does it mean?
[15:06:57] <cnc_engineer> Hi, everyone.
[15:07:54] <cnc_engineer> I get an error message "tk lib not found" when I supply "./configure" command, Why?
[15:12:05] <a-l-p-h-a> cnc_engineer, someone will answer that in a sec... I know they're around. :)
[15:12:25] <a-l-p-h-a> are you sure yuo have tk lib installed? [that's the first Q]
[15:12:46] <SWPadnos> tk-dev, more likely
[15:12:53] <SWPadnos> tk8.4-dev or some such
[15:13:05] <a-l-p-h-a> SWPadnos would be the super guru

[15:16:14] <a-l-p-h-a> seriously Q now... I have an engineering friend that wants to tinker with CNC after seeing my setup... but he's too cheap to get metal working tools, so he's building a prototype out of MDF... any suggestions for him?
[15:16:28] <SWPadnos> cnc_engineer, do you have the tcl/tk development packages installed?
[15:16:32] <a-l-p-h-a> btw. he's having a heck of a time, trying to screw things into the side of mdf
[15:17:07] <cnc_engineer> how can i check that?
[15:17:24] <SWPadnos> I'm not sure on fedora. I don't know the name of the RPM
[16:01:45] <jepler> on my fedora core 2 machine, the package names seem to be tcl-devel (and tk-devel)

[21:57:17] <Chris_sub_1> Is it possible to run the PID tuning example having just done an install of EMC (not a local build)?
[22:02:04] <skunkworks> Yes
[22:04:49] <skunkworks> you could look at the etch-sevo sample or lathe_pluto.. (don't know if lathe_pluto is in the installed version)
[22:05:19] <skunkworks> there is a bunch of pid samples including the mazak
[22:07:18] <Chris_sub_1> I would like to run m5i20_pidtest.hal but I can find the script for starting the realtime module and HAL library. Note that I am still fairly clueless on the linux cmd line.
[22:07:46] <Chris_sub_1> Uh...that should have read "can't"
[22:08:45] <Chris_sub_1> The hal file says to run 'scripts/realtime start'.
[22:08:56] <skunkworks> I don't know it off the top of my head - but it is in the user manual... - how to run a hal file.
[22:11:13] <skunkworks> I think it is halrun -f filenam.hal
[22:22:19] <Chris_sub_1> That's what it says in the test hal file, but one of the steps before that is to setting an env var so halcmd can find realtime modules: 'export HAL_RTMOD_DIR=./rtlib'. I can't find rtlib.
[22:23:10] <Chris_sub_1> Or am I being stupid and it/they are created at runtime?
[22:32:19] <jepler> Chris_sub_1: the comments in that file are out of date.
[22:33:36] <jepler> Chris_sub_1: to set up realtime, run a HAL file, and then give a halcmd prompt, simply run: halrun -I m5i20_pidtest.hal
[22:35:37] <jepler> it does everything the "scripts/realtime start" "export ..." and "halcmd" commands to
