Ok i found I have to use comp to compile probekins.
sudo comp --install probekins.c
that will compile and copy probekins module to correct place.
Now I am trying to figure out my next round of errors.
with linuxcnc running I get the error
a search of hal.shm show it takes 3 arguments. component, key, size.
if stlcorr.py the first 2 args are there. Im guessing the size=2048 is supposed to go to that third agument somehow.
I changed to file like so:
and at the top of the file after the imports, I added
size = 2048
Now I have the error (luckily!)
changed size in the HAL and the .py file to 14400
not sure how large of a stl that will handle, but I can change later if need be.
It works now!
Hope this helps somebody!
stlvis is now working with:
alan@alan-cnc:~/Desktop/probekins$ ./stlvis.py -b 0,0,9.5,3 probe.stl
On this page, wiki.linuxcnc.org/cgi-bin/wiki.pl?LockedMemory It tells to ad "* - memlock 20480" to /etc/security/limits.conf
It was already there though. It also says to add a line to /etc/pam.d/common-session if you have lucid 10.10, I have 10.04.
I added the line with no change, then returned it back to how it was.
A side note, with probekins module loaded, axis shows joint 0, 1 2 instead of X Y Z, I'm guessing I have to dig study probekins.c and trivkins.c to figure out how to get it to display as it was? Or has anyone figured this out yet.
