One for Jazz.
Got my PM25 clone running today and works brilliant but...
I used overkill Nema34 (the grief of my X2 knocked me a bit) seem good motors so that's all fine.

Anyway. If I hit my soft limits at 2000mm/min the motors slightly over travel and put my position out by 0.2mm.
I would say this is down to the rotor inertia of the overkill motors. Would you agree?

Simple solution... Don't hit the limits
I do have some decent nema23 size for it. I'll make some mounts so I can try them out.
