Gene is getting good results with his 3-phase steppers and no PID control
in LCNC because the 3-phase steppers have internal PID position control
loops in the motor driver electronics. These motors have an encoder wheel
for feedback. So these steppers are basically the same as a servo with
feedba
This is a quote from peter on the forum..
'I have done some experimentation and have found that you can get better
stepgen following performance on systems with moderate jitter by using a
PID loop for position control instead of the stepgen drivers built-in
position control loop.
The problem with

All my machines - steppers and servos are running pid.I think Peter
forgot to mention - The reason PID is recommended is because it handles
latency spikes way better. We have seen situations where a latency spike
confuses the hell out of position mode stepgens. (ymmv)

Greets - although I haven't read every post of late, I've been an LCNC

for many projects.
Like many, I started with software stepgens driving open loop steppers,
and although my shelves are full of them, I typically reach
