Try using Halscope (trigerred from orient enable) to compare the position, target and velocity.
If it takes too long to get to position try more P, if it gets there rapidly then takes a while to settle, try less P. If it takes a long time to pull in to final position then add a little I.

Had about an hour to toy around with this tonight - first time in weeks. I had some success getting halscope to show me signals, but no real progress on the PID.

Also my zero point is whatever the position the spindle is in when my configuration boots. I was under the impression it should reset to zero once the index is seen. Thoughts?

Index will only clear the spindle position if index enable is true

Can you post your existing HAL and INI files? That might help with diagnosing you tuning and spindle issues

To check the spindle index you can (in a terminal window with LinuxCNC running):

halmeter signal spindle-index &
halcmd sets spindle-index true

Then watch spindle-index's state as you manually rotate the spindle
If it's working, it should go true when set via the sets command and go false
when index is detected at just one angular position of the spindle

This is working as intended - reliably sets to False in the same position.

Realized today that my Y-axis encoder direction is wrong - when I flip the sign of the encoder in my INI file, the machine faults as soon as I enable the motors with a joint follow error.

As far as I can remember, when I was first setting this up I was able to flip the sign in the INI file no problem. Any ideas?

if you flip the encoder scale you also need to flip the analog output scale
( OUTPUT_SCALE in the ini file) or you will get a runaway (positive feedback)

Thank you Peter!

I had to take a break from trying to figure out the spindle/ATC and just cut something today. I've had this machine now for 2 years and haven't made any computer-controlled cuts and it's been eating away at me.

The cuts aren't great - I need to relevel the machine, tighten the X-axis gibs, and spend more time tuning the servos. Feeds/speeds were back of the envelope and clearly too much for the little 3/16" HSS tool in the pocket :laugh:

But to me, today, this is a trophy. Really appreciate everybody's help and I'm feeling motivated - leaving for IMTS tomorrow and can't wait to get back to the machine next weekend.

Re-tuned XYZ axes and am pretty happy with where they are now. Still believe the X gibs needs to be tightened because I hear a thud when changing directions from X+ to X- (tightening the gibs moves it in the X+ direction).

Thinking about the spindle position PID - is it possible that running my VFD in vector mode is causing trouble with the Linux control loop?

When I was running the part in the last post I heard some variation in my spindle speed so I need to look into the VFD parameters there as well.
