PM42L-048 Z axis for MicroCube (CXY)

thingiverse

I've been storing some motors that I salvaged from old 2D printers, intending to utilize them on a 3D printer for quite some time now. These budget-friendly "can" motors boast a step angle of 7.5 degrees, which is significantly lower than the standard NEMA type motor (1.8 or 0.9 degrees). This reduced accuracy can be a major drawback for something like an X/Y axis, but I've observed similar motors being used on Z axes before, where the leadscrew provides substantial reduction and compensates for the motor's limitations. Given that I'm unable to source a NEMA 11 motor, which is originally required for this 3D printer's Z axis, I decided this would be an ideal opportunity to test out the PM42L-048 motor, whose torque appears comparable to that of a NEMA 11. Once I've assembled this printer, I'll provide an update on its performance and let everyone know how well it works.
