Thanks. Will look into that.
Now another question: Nema 17 stepper motors. On your parts list you refer to a 2A 48mm Nema 17:
Are the 2A "fixed" I mostly find the Wantai Nema17 Stepper Motor 42BYGHW609 for a very good price. But it has "only" 1.7A and 40mm - would that be strong enough? Additionally the steppers are 40mm (height) instead of 48
What do you think?
