I did it didnt help, Without a load i can get it to go up to like 400mm/s. the issue is my steppers have pressed on pulleys, and the shafts are 4mm, so basically I would need a whole new set of steppers and pulleys, I dont feel like paying that much just to see if its any faster, however I might print some pulleys with polycarbonate using a fine nozzle that would slip over the existing ones.
