Definitely a better solution but I doubt time will alow for it now. 

I do think it is worth doing though, so I think i will set up a pc and ask a friend who is better skilled than me in terms of programming to have a look

Thanks Andy

did you run that through an AI to generate stuff?

I finally managed to sort it out and update my .ui file to GTK+3. I wish there was a better guide for the various LinuxCNC-specific components and the migration necessary.

I would not, unless it is really required.

Ahh, I missed that

As far as the spindle speed changing goes, it would probably be helpful to
disable the PID/feedback, in case there's something odd going on there.

Disable the feedback by setting all PID terms to 0 except FF0 so the
PID component is just a pass through.


Another thing for debugging would be to dump all the hal pins when
things are working correctly and when misbehaving:

halcmd show all > ok.txt

halcmd show all > bad.txt

and post the results here.
 

Yes that beautiful thing has been moved around to different places and has grooved well over 10,000 pairs of drumsticks (200k+ in gross sales) in nine years with no issues. Never had a problem with the software or anything until just recently. I know it’s an old version but it’s always worked. It’s just having a few issues. I may need to just upgrade the whole thing and start from square one.

Has it ever worked?
Why LinuxCNC 2.5? That's really rather old.
