[11:41:50] <skunkworks> jepler, heh - I started typing something and I think one of the little ones must have hit enter.
[11:42:03] <skunkworks> jepler, did you play with the laser this weekend?
[11:46:52] <jepler> skunkworks: yeah I got some time to play with it. didn't get any great results yet though.
[11:47:28] <skunkworks> what kind of laser control? is it just on/off or can you control the power?
[11:48:56] <jepler> skunkworks: it's just on/off with the GRBL firmware.
[11:49:22] <jepler> https://photos.google.com/album/AF1QipPIEGKTZWQlLgXFGwfc5KMj3Pn7lQGttgZv4HKU/photo/AF1QipP7YekCevBW_BTDpaydyD2ss4fE7zNSX51mdzkA is one of the better results I have had so far.
[11:49:41] <jepler> using custom bitmap -> grbl gcode conversion
[11:49:50] <skunkworks> That link does't work
[11:50:04] <jepler> oh no
[11:50:38] <jepler> https://photos.google.com/album/AF1QipPIEGKTZWQlLgXFGwfc5KMj3Pn7lQGttgZv4HKU
[11:50:42] <jepler> try that one?
[11:50:49] <skunkworks> same 404
[11:50:52] <skunkworks> 40
[11:50:55] <skunkworks> 403
[11:51:04] <jepler> huh
[11:51:29] <skunkworks> sorry - first was 404 and second was 403 (don't have access)
[11:51:39] <jepler> https://photos.google.com/share/AF1QipN0TPuFG81XVaI97F6jvZ_qceE-OqRCQS-h4hKGraKFZp3u4UhMEtCiG204yccAUg?key=SDJ3T2FiQjZQNFd3TDc5c3FBdDQ4VkZPOXowWnF3
[11:51:46] <jepler> do I not know how to share photos with stupid google?
[11:51:48] <skunkworks> Got it!
[11:51:56] <jepler> anyway, that last image there
[11:52:20] <skunkworks> reminded of dot matrix prnters :)
[11:52:21] <jepler> the "," at the left is because I partially printed the same design after re-homing
[11:52:22] <skunkworks> cool
[11:52:36] <jepler> you can see the backlash in the vertical of the middle "f", it's fairly modest
[11:52:40] <jepler> no backlash comp in grbl afaik
[11:52:48] <skunkworks> nope
[11:53:31] <jepler> you can also sort of see the periodic variation in burn strength if you look at the crossbars of the "F"s and much moreso if you look at the jellyfish
[11:53:31] <skunkworks> https://github.com/bjj/2x_laser
[11:54:15] <skunkworks> http://www.buildlog.net/forum/viewtopic.php?f=16&t=557&start=130
[11:55:22] <jepler> I think the period of the variation is the same as the turn of the X screw, so my first theory is that it lifts/lowers the laser on a 1 screw-turn cycle
[11:58:13] <skunkworks> Hmm - wierd
[12:01:13] <skunkworks> is this a platform to test streamer?
[12:01:55] <jepler> anyway, the control board is just bolted to the back of the machine and consists of 2 standard stepper drivers, a ULN2003 to switch the laser, and a standard-pinout arduino pro mini knockoff. unfortunately, the boards are soldered, not socketed.
[12:03:28] <jepler> my plan had been to make a DB25 to 26-pin x .7" pseudo dip board so I could use the stepper drivers as-is, but I'm not sure if I'll successfully desolder a 26-pin device without ruining anything
[12:04:30] <jepler> not that I need all of the pads to survive, only 6 signals are used (4 for step+direction, 1 enable, 1 spindle) :-P
[12:08:50] <jepler> the board

[13:11:15] <jepler> I'm not 100% sure what all the stray lines are
[13:12:19] <jepler> the first time I did this print it started down at the hook of the "J" instead of at the top (the top is printed first). I re-homed (so you can see the excellent "repeatability" of the homing procedure) and printed again from the start
[13:12:26] <jepler> but I'm not sure what the stray lines at the top are

[16:13:58] <cradek> #5 is wrong
[16:14:42] <cradek> #8 is surprising to me, but right
[16:16:42] <cradek> the reminders to quote are nice, except when they're silly like $PID
[16:17:36] <seb_kuzminsky> for #5, where does scripts/linuxcnc use LINUXCNC_CONFIG_PATH? i dont see it
[16:18:09] <cradek> oh I meant the tilde, assuming the picker expanded it
[16:18:23] <jepler> tcl/linuxcnc.tcl.in: variable CONFIG_PATH {@LINUXCNC_CONFIG_PATH@}
[16:18:30] <jepler> it uses it, but not by inheriting it from the linuxcnc script
[16:18:34] <seb_kuzminsky> cradek: ah
[16:19:21] <cradek> saying "~" is never what you want is very bold
