Yes, the ones I've been using have that way of tuning them too. What I find

Windows software for tuning is pretty standard even on the more expensive
integrated servo systems. Teknic Clearpath needs Windows software for
configuration and tuning, as does one Chines brand that I’ve used.

Hi guys again and thanks for all the answers :)
Well, indeed the problem as Todd suggested is because of the driver
limiting acceleration and velocity. I found in the manual that this can be
changed and they recommend using a value 10 times higher than what LCNC
commands. This is to avoid this pea

My experience has been the opposite Sam. I have no PID's in the config

Hi
Hi Sam,
Yeap, seems like the servo motor limits its acceleration within itself. The
problem is the manual doesn't help and the only thing I could find is a
smooth factor so I'll tell him to play with that value and see what
happens. It seems the drive has more settings available when you tune it

With steppers - at least they stall.. The fact that the servo drive isn't
tripping a following error makes me think they are not setup correctly.
It should notic
Hi guys, hope you are all doing well.
My brother is changing some stepper motors to servos from a machine with
LCNC 2.4.3 and a mesa 5i20. The servos are D2 model from Hiwin.
The problem he's having is that, in rapid movements, after LCNC completes
its motion the servo motor keeps running until i
