cofhal - I will look at your files now, I did have another idea as well - could i simply use two stepgens? one for step.dir for spindle and another one for the "C" axis? and have a mesa output pin switch a dpdr relay to simply alter where the same motor gets the input?

one more question before i forget: what issue could be encountered by having a different model of servo driver? Given that you are driving both the spindle and c-axis both with step/dir signals, you just need a driver that can output step/dir, right?

There's no need to use the same servo motor for both, but keep in mind that for it to work, you must connect the servo motor's encoder feedback. I believe your servo motor has a 2,500-pulse encoder. I can help you configure it with the manual.

I think it would be a bad idea, since you could use the same servo motor for both functions.

@COFHAL
Have you ever used spindle synchronized motion (eg G33 or G33.1) with the config you posted above?
Just wondering if you are also affected by the erratic behavior bug described here:
