Frequently asked questions
Which bore do I need?
The diameter of the shaft it goes on. Most NEMA 17 stepper motors have a 5 mm shaft, which is the default.
Can it replace a metal pulley?
For light, slow loads, yes. For high loads or speeds a metal pulley is better. Print with 0.12 mm layers for clean teeth.
