So i am trying to build a fabber (3d printer) using steppers from scrapped printers. Currently I am trying to decide between the big unipolor motors from HPs or the square bipolar ones from Epsons. If the accuracy and power is comparable, I would prefer to use the bipolar, given the size constraints in my design. The motor is labeled EM-434 and came out of a Stylus C60. Anyone know anything about these motors? Degrees/step? Voltage?
The HPs are PM55L-048 and are 7.5 degree, but I dont know the voltage. These are unipolar.
Any help would be greatly appreciated
The hp's are 24 volts ,30 oz/inch holding torque and if you
also use the gear from the printer ( the metal one ) you
end up with about 1.3 degree steps.
But i suggest to get bigger motors for any real work.
