Stepper Motor Related

You'll have to define "high quality steppers" for me and what's your budget.

NEMA 17 Steppers (2A /50oz) are available from $259 down to $6 and all will move fairly accurate 1.8° with each step. Are you worried about corrosion resistance, bearing materials, avoiding vibration damage to bearings (false brinneling), EMI shielding, EMI emissions, etc. what exactly are you looking for to make your 3D printer "better" and what are you printing that makes the $6 motors unacceptable?

Any NEMA17 motor should have the same "face" dimensions. They generally also have an appropriate 5mm shaft.

I do not see any point in trying to find "higher quality" motors. Higher TORQUE, yes!

For anything other than a small physical build, I'd also advise axis motors with built in connectors, rather than flying leads. That allows you to use appropriate cable lengths rather than having connectors at fixed distances from the motors.


The printer capabilities will be down to to motor torque and the stepper driver capabilities, plus correct mechanical setup and tuning - and the quality of the control board.

It looks like most people are using very basic control boards with Voron builds. If you want a really good system, I'd go for a Duet3D controller - I've used those for both simple three axis delta type and large CoreXY with toolchanger, eight motors and five heaters all in.
