I have a Type A series 1. Pinchwheel replacement I got has a diameter of 10.5 mm, original one was 7.5mm diameter. For a 5mm shaft.

After calibrating my steps/mm, the motor skips because the increase in pinchwheel diameter requires more torque from the motor. I need to find a good sharp pinchwheel that is smaller in diameter or somehow boost torque to the motor. Any suggestions?


I am using pronterface and KISSlicer
