What do they do?
I get the impression that they are lathe roughing cycles (turning,
facing, boring?) If so then the same thing can be easily performed by
simple loops in G-code.
I eve
Thanks for the discussion on stepper motor performance. We have all
confirmed that the limit in speed lies not in the software, but in the motor
and its supply voltage. That's what I wanted to be sure about.
I want to start another subject: G71,G72,G73 cycles for lathes.
I have been using similar

This isn't exactly true... I was looking at the definition of the

I tested a Nema 23 two stack stepper (bipolar) in closed loop with EMC2
lately. The stepper driver is a Gecko 251 at 45V and 3A. The encoder is an
