I’m having some troubles with my MPCNC wiring. When I detach my stepper motors from RAMPS and try to move axis by hand I get lots of vibration and drag from the motors as the coils would be connected (even without any powers on). I followed MPCNC wiring tutorial and connected my motors in parallel.
Now I’ve connected black wire (A) leading from RAMPS to the black wires of the both stepper motors. Same goes with the green wires ©. Now the red wire (B) I’ve attached to the red wire of the first stepper motor and to the blue wire (D) of the second stepper motor. With blue wire I’ve inverted connection.
When I move my axis I start to get drag and vibration as if magnets of the motors are activated. Problem disappears when I detach either first or the second motor. Problem start if I connect parallel even only the other coil (black and green wires or red and blue). What I’m doing wrong here?
