Hello! This is my first thread, so i hope i'm posting it right.
I'm building a JGRO router but with some changes in the design (location: middle Europe) and i have some problems with stepper motors. Steppers seem to stall, but it happens at random times and in a range of rpm. Even at lower speeds there are strange sounds comming out of the steppers (sounds like worn out bearings) and they are not running smoothly. I saved the steppers from an old label printer. Are the steppers really the problem or is there something else that i missed?

Drivers: PMinMO L297-8 drivers, 32V 1.4A, halfstepping
