Hey all,

I have a lens that I need spun continuously by my 4th axis rotary while a grinding pin carves out a curve.

So far I've used Trace to map out the appropriate curve for my custom grinding tool but I am struggling to find the appropriate toolpath strategy to just spin the A-axis continuously while it follows the guide curve.



See attachment, I already built a fixture to hold the 4th axis perpendicular to the optical axis. This is company property so I don't have permission to hotwire it to an Arduino-controlled stepper driver or anything like that.

I've also tried jog locking the 4th axis on the Haas mini mill I'm using while the code runs and that was unsuccessful.
