[08:16:52] <skunkworks> rene_dev_: I installed servoterm on 2 machines (windows and linux) and I don't get the 'launch' button
[08:17:12] <skunkworks> in the extensions page
[08:18:13] <jepler> andypugh: configure process creates Makefile.inc from Makefile.inc.in. Makefile includes Makefile.inc.
[08:18:26] <skunkworks> Hi jeff
[08:18:33] <jepler> andypugh: Makefile.modinc{,.in} are related to building out-of-tree components and are not used while building LinuxCNC itself
[08:18:36] <jepler> hi skunkworks
[08:20:55] <skunkworks> rene_dev_: huh - on linux it shows up as a 'chrome apps' in the start menu..
[08:20:59] <skunkworks> that works

[10:23:08] -!- BuildTheRobots10 has joined #linuxcnc-devel
[10:24:36] <skunkworks> related question - on the windows side - what driver do I need for the 'stmbl virtual com port'
[10:25:57] -!- Roguish has joined #linuxcnc-devel
[10:26:27] <skunkworks> on the linux side I get 'Connecting to /dev/ttyACM0'
[10:26:53] <skunkworks> sometimes jiggering with usb cable - plugging/unplugging I can get it to connect
[10:27:21] -!- BuildTheRobots10 has quit [Ping timeout: 240 seconds]
[10:31:57] <skunkworks> hmm - seems like closing and re-starting servterm seems to make it connect more consistanty

[12:16:14] <skunkworks> :)
[12:38:30] <skunkworks> hv hooked up (30v..) I should find a motor to hook up...
[12:41:05] <skunkworks> now I get 2 flashes (feedback error) makes sense instead of 9 (hv comm error)

[19:31:47] <andypugh> I have been looking to add the hal_gpio (raspberry pi GPIO) from Machinekit to LinuxCNC.
[19:32:17] <andypugh> In doing so I have found an odd entry for hal_bb_vpio
[19:32:50] <andypugh> https://github.com
[19:33:20] <skunkworks> andypugh: the drive powers up and communicates with servoterm
[19:33:32] <andypugh> I don’t think that hal_bb_gpio belongs in hostmot2? https://github.com
[19:33:41] <pcw_mesa> bb=BeagleBone?
[19:33:48] <andypugh> skunkworks: Cool, have you made the motor go round yet?
[19:33:58] <andypugh> pcw_home: Yes, BeaglBone
[19:34:16] <skunkworks> no - just grabbed a small brushless servo with hal sensors and encoder to play with
[19:34:35] <andypugh> You can spin a motor pretty easily in open-loop mode
[19:34:42] <skunkworks> andypugh: do you know if you can run with just hal sensors?
[19:34:44] <andypugh> (from servoterm)
[19:34:47] <skunkworks> (say for a spindle?_
[19:34:54] <andypugh> I think so, yes.
[19:35:02] <skunkworks> I have not worked though all the docs yet
[19:35:21] <andypugh> The docs are horribly incomplete. I blame me, for starting and not finishing.
[19:35:25] <skunkworks> heh
[19:36:00] <skunkworks> the only think so far a bit odd is it doesn't like to connect all the time.
[19:36:05] <skunkworks> (usb)
[19:39:14] <andypugh> I think you can spin a motor with:
[19:39:45] <andypugh> hv0.pos = sim0.vel
[19:40:04] <andypugh> hv0.d_cmd = 0.5
[19:40:14] <andypugh> hv0.enable=1
[19:40:28] <andypugh> You might also need to set sim0.freq
[19:40:36] <andypugh> sim0 is a function generator.
[19:41:01] <andypugh> hv0 is the high-voltage drive side
[19:41:17] <andypugh> (just typing sim0 or hv0 will show all the pins and values)
[19:41:39] <andypugh> It’s like LinuxCNC HAL but with a simpler syntax and auto-linking components.
[19:45:04] <andypugh> skunkworks: You can try the stmbl IRC (it’s on irc.hackint.eu rather than freenode)
[19:46:58] <skunkworks> andypugh: oh - cool thanks
[19:47:28] <andypugh> rene might be still awake, though it’s late in Germany.
[19:59:03] <skunkworks> andypugh: there isn't a hv0.enable
[19:59:17] <andypugh> What is there?
[19:59:24] <skunkworks> it is en I bet
[20:00:13] <skunkworks> heh - not rotating inconsistantly..
[20:00:22] <skunkworks> * rotating inconsistantly
[20:01:02] <andypugh> Try more hv0.d_cmd
[20:01:10] <andypugh> (that’s the direct current command)
[20:01:51] <skunkworks> makes it run more smoothly about the same rpm
[20:02:08] <skunkworks> (about 1rpm)
[20:02:16] <andypugh> Yes, rpm will be the same (sim0.freq to change that, I reckon)
[20:02:28] <skunkworks> cool
[20:03:17] <skunkworks> cool
[20:03:19] <skunkworks> :)
[20:03:34] <skunkworks> well - that seems to work, now to actually figure out how to configure it.
[20:03:37] <skunkworks> :)
[20:03:40] <skunkworks> thanks
[20:05:14] <skunkworks> does the fan come on only when needed?
[20:05:43] <andypugh> Yes, I have never seen the fan come on
[20:06:59] <skunkworks> heat sink is geting warm
[20:07:14] <andypugh> What current?
[20:07:19] <skunkworks> is that actual current? 1=1A?
[20:07:23] <andypugh> SHould be
[20:07:35] <andypugh> Is the motor getting warm too?
[20:07:41] <andypugh> Be careful of that in this mode
[20:08:27] <skunkworks> sure - but the supply is only .5A - I should be good
[20:08:29] <skunkworks> :)
[20:09:08] <andypugh> Dont set the d_cmd higher than the supply current, that will pull the HV down too low
[20:09:48] <skunkworks> .5 it is ;)
[20:09:56] <skunkworks> very neat
[20:12:02] <skunkworks> andypugh: http://electronicsam.com
[20:12:48] <andypugh> You have resisted the urge to fit the case?
[20:12:54] <skunkworks> so far...
[20:12:56] <skunkworks> :)
