09:40 AM Tom_L: buildbot is out with the flu it seems..
01:46 PM andypugh: Does anyone see a reason not to just merge that PyVCP update from Oleg?
01:54 PM jthornton: looking
01:55 PM jthornton: is it the linuxcnc issues?
01:55 PM jthornton: I'm not finding it
01:56 PM andypugh: https://github.com/LinuxCNC/linuxcnc/pull/568#issuecomment-471213759
01:57 PM jthornton: looks good to me
01:58 PM jthornton: nice docstring!
01:59 PM hazzy-m: andypugh: the changes he made are fully backwards compatible, I see no reason not to merge
02:00 PM andypugh: I pressed the button.
02:01 PM Tom_L: ^^ it's all his fault
02:03 PM jthornton: is there a way for me to download the images that tseufl wants to add to master? https://github.com/LinuxCNC/linuxcnc/pull/209
02:03 PM hazzy-m: andypugh: PRs 554 and 555 also seem like they would be ok to merge
02:04 PM hazzy-m: jthornton: click on the comit and view file
02:04 PM hazzy-m: https://github.com/LinuxCNC/linuxcnc/blob/cdb3bc1d4bfd6ce8661e72490a527670e21987d9/docs/src/config/images/switch-nc-series_tmpl.svg
02:05 PM jthornton: thanks
02:11 PM jthornton: dang he did a lot of work on the images but didn't remove the old ones so now all the ones he made have the wrong name
02:12 PM jthornton: and 2 years ago :(
02:14 PM hazzy-m: ouch
02:14 PM hazzy-m: they look really good
02:31 PM JT-Shop: yea I need to get a copy of them and see about putting them in master
03:23 PM skunkworks: andypugh: do you know of any pins in the stmbl that is power?
05:19 PM andypugh: There are +24V pins on the IO connector.
05:44 PM hazzy-m: andypugh: I think he means power as in how many watts the drive is putting out. It has a current pin, but no voltage
05:45 PM andypugh: Yes, I figured that out reading the same question on the STMBL gitter.
05:45 PM hazzy-m: oh great! I should go listen in and see what I can learn!
06:44 PM * pcw_home copy pastes "Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488"
06:45 PM pcw_home: where Torque = motor torque constant*current (full 3 phase current, not sure what STMBL reports)
07:12 PM skunkworks: it looks like they have already calculated it..
07:12 PM skunkworks: mechanical power: pe0.p_m
07:12 PM skunkworks: electrical power: pe0.p_el_ac
07:12 PM skunkworks: (pins within stmbl)
07:15 PM pcw_home: you would need the motors torque constant (although you can get close with just (electrical input power-electrical losses)*motor efficiency
