Description

Materials and methods

I used a Nema 17 Stepper motor Kysan 42BYGH4803. Remember the pololu driver current limit is default set to 0.7 times the rated current to be save. If it is missing steps turn the drive up with small steps.

Needed:
Stepper motor: Nema 17 Kysan 42BYGH4803
Bearing: 608ZZ
Drive gear: MK7-compatible 5MM shaft
Spring: Outside diameter: 10mm, Inside diameter: 8mm, Total coils: 9, Length: 25mm
Bolt: 4x M3x20
