Just wondering with 4th axis rotary, is there a software that anyone can recommend that does a continuous rotary movement. Keeps turning 360 while cutting rather than a left to right finishing at 360.
I can't recommend any SW for this, but I can suggest a HW mod for it.
I set up a 555 oscillator (or something similar in CMOS, I forget) with a variable potentiometer for the speed, and an SPDT switch. The switch chooses between the pulse drive from Mach3 and the output from this oscillator. Switch to oscillator,adjust rotation speed: slow lathe.

Cheers
Roger

That would be an interesting mod for sure, do you know if something like that would work for uccnc?
