See these specs on motors they may match yours.

Search the community as someone else has replaced their’s.

ANy basic Nema17 that uses around 1A of current and is the same physical size will do.

+Anthony Bolgar just to add, unless they changed it recently, the original stepper motor is a 0.9degree 400 full step motor.

No problem replacing with a more common 1.8degree 200 full step motor but you need to change the step per mm setting in smoothieware.

Wouldn’t 1.8200 be the same as .9400?
