Help with wiring new motors?
June 22, 2015 01:18PM
I got some NEMA 17 4.8kg/sec motors to replace my 2.6kg/sec motors. The new motors have a different wiring color scheme. (Guess I shoulda thoughta that!)

Not being an electrical guy, I don't know how to connect the wires on the new motor correctly. Can someone help me sort this out? -- which color wire on the new motor maps to which color on the old one?

I've attached pictures of the old motor wiring at the motor and on the RAMPS board, the new motor wires, and the connections diagram that came with the new motor.

Hope that helps

It looks like on your old steppers Green/Yellow are a pair and Red/Grey are a pair. On you new Stepper Blue/Red are a pair and Black/Green are a pair.

Thanks! I found this too, which seems to map to what I have.
