I pulled these stepper motors from a set of CMY colour changing fixtures which were used as donors.
Steppers are model no. 42BYGH026-1 and have standard NEMA17 mounting. Motors are standard 1.8 degree per step, are bipolar motors (so no center winding tap) and have a winding resistance of 6 ohms.
Lot was pulled from working machines and is in good condition. These could be very useful as actuators in a beam table setup or for someone who is looking to build their own CNC milling machine or 3D printer. They should be no problem to integrate in a RepRap design.
Looking for $125 (€100) for the entire lot, or trading for a low cost scanner set worth about the same amount (e.g. Scaneco20 or LW20K).
I also have a set of HUGE dichroic colour flags which I am going to put up on sale once the repaired units have been sold and I confirmed that the dichroic flags are any good for laser purposes.
