Thanks for the quick reply John, I'm using the rotary axis mostly for doing ring billets for pool cues. I'll include a video (not mine) that illustrates what I'm looking for. I'm having issues with the cutter not comming back to the same slots, which gives me a sloppy fit. Maybe there's something in the settings I should do?
i use Acorn CNC and the worm drive is driven by a NEMA 34 closed loop stepper from stepperonline.

Thanks

Kim
