I need some assistance getting continuous 4th axis rotation on my Haas Super Mini Mill (pre-NGC). I have converted my 4th axis into a rotary table for lens grinding and need it to rotate continuously as a grinding tool sweeps across the surface and OD of a lens.

I have seen posts that recommend using jog lock which only works temporarily as movement stops once I switch out of the jog screen and over to the program screen.

The controller doesn't recognize the G33 continuous rotary motion command either.

Here is a snippet of the code, I have included where the 4th should start rotating and where the cutter disengages from the part and starts moving to the next pass.

Thanks for your help.
