That was my thinking. It would also need to be a smart motor driver that senses motor rotor position either via encoder or back emf and adjusts motor current based on load.

So > weight shouldn't matter. Should it? OK,this is EXTREMELY bizarre! In open loop, how could LinuxCNC know anything about the load on the motor? I think maybe it is some kind of electrical noise issue, the switching noise from the drive could well increase as motor current increases. Possibly you could put some ferrite cores over the motor leads.
