I've had a few cheap motors saved from old 2D printers I've been meaning to use on a 3d printer for a while now. These cheap "can" motors have a step angle of 7.5 degrees which is quite lower than your usual NEMA type motor (1.8 or 0.9 degrees) which can be a big drop in accuracy for something like an X/Y axis, I've seen similar motors used on a Z axis before though as the threaded rod adds alot of reduction and so this motor should be adequate. I figured this would be an excellent place to use this motor as I cannot source a NEMA 11 motor which is originally needed for this 3d printer's Z axis. This PM42L-048 motor seems to have similar torque to a NEMA 11 and so far seems to work just fine.
