Plug and play!
This is updated wiring kit for the LowRider CNC, it will still work with the Mostly Printed CNC if you account for no resistor.
2-LowRider CNC Y&Z stepper wires, MPCNC X&Y- 1M (39.5") between plugs. Wired in Series.
1-LowRider CNC X, MPCNC Z stepper wires- 2.5M (98.5").
You should tape or otherwise secure the connections to relieve any stress of repetitive motion. Matching clip side to clip side should make your steppers more in the correct directions, if not flip one of the stepper plugs to reverse its direction.
