#linuxcnc-devel Calendar

08:21 AM jepler: also unless you're in exact stop mode, milling a circle with that toolpath (compensation or not) will leave a little bit uncut, because you get the blend at the start and end of the circle
10:50 AM hazzy: Happy Labor Day!
10:50 AM hazzy: Is there an easy way to check the linuxcnc version in a python script?
10:51 AM hazzy: maybe something like linuxcnc.VERSION ??
10:55 AM hazzy: aha, I see "LINUXCNCVERSION="2.8.0~pre1"; export LINUXCNCVERSION" in scrips/linuxcnc
10:55 AM hazzy: so I can do "os.environ.get('LINUXCNCVERSION')"
10:55 AM hazzy: thanks!
04:11 PM andypugh: This seems like a daft question, but where does the useful info that used to go to dmesg end up in a uspace build?
04:50 PM jepler: andypugh: stdout+stderr
04:51 PM andypugh: where does stdout go if you start fron the GUI?
04:52 PM andypugh: I see some ecidence of output in linuxcnc_print.txt
04:52 PM andypugh: (I am trying to find where the mesa card pinout data goes, but I don’t have a uspace machine that can connect to a Mesa card)
04:53 PM andypugh: I have a VM on the Mac, and RTAI machines on the machines.
04:53 PM andypugh: And my development motherboard doesn’t boot any more.
04:54 PM jepler: linuxcnc_print.txt and linuxcnc_debug.txt in $HOME ?
04:54 PM andypugh: Yes
04:55 PM jepler: that should be everything, but of course it's overwritten each time you run linuxcnc
04:55 PM andypugh: The dmesg output from hostmot2 is rather useful for figuring out where to wire things.
04:55 PM jepler: $ halrun -I ../pci.hal
04:55 PM jepler: Note: Using POSIX realtime
04:55 PM jepler: hm2: loading Mesa HostMot2 driver version 0.15
04:55 PM jepler: hm2_pci: loading Mesa AnyIO HostMot2 driver version 0.7
04:55 PM jepler: hm2_pci: discovered 5i24 at 0000:06:00.0
04:55 PM jepler: hm2/hm2_5i24.0: 72 I/O Pins used:
04:55 PM jepler: hm2/hm2_5i24.0: IO Pin 000 (P4-01): StepGen #0, pin Step (Output)
04:55 PM jepler: in a terminal you get this, I think it's the output you mena
04:55 PM jepler: mean
04:56 PM andypugh: OK, I seem to have pointed the chap in the right direction, ball now in his court.
04:56 PM jepler: I would expect it to end up in one of those two files named above
06:00 PM skunkworks: pcw_mesa, what kind of performace decrease do you get if you don't use the velocity dirivitive in the pid (for stepper pid setups)
06:08 PM jepler: sigh
06:08 PM jepler: well at least norbert shared his secret script for generating gmoccapy's .pot file
06:12 PM andypugh: <checks for norberts> I find myslef disliking the way he does almost verything, but admiring that he does anything. There is so much built-in behaviour in his GUI that should be one or teo levels up.
06:13 PM kb8wmc: JT: I have the pins list
06:13 PM kb8wmc: I just did not write it to text file
