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

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

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
AMT102 connected TTL to a MESA 5i20 (P2) through a 7i33. The G251 step/dir
signals are connected directly to the 5i20 (P4). The objective was to see

The motor runs very smooth and the following error is maximum about 6 counts
at high speed. The counts per rev is 2000. The highest speed is about 2000
rpm above which the motor suddenly stalls and then a fault error is given.
