I am building an Arduino (grbl) based router, and I have purchased 3 NEMA 23 6 wire stepper motors. They come with pretty short wires. If I hook the wires up directly to the controller everything works OK. However, when I finally construct the CNC router with stepper motors, they will have to be anywhere from 3 - 4 feet away from the controller. I need to buy or build longer wires.
I have tried 2X to construct a cable, one time using solid wires, another using braided wires with connections I cut from Arduino breadboarding wires and pins ( I am running the steppers at 24v).
Each time, when I connect them up as before, the motor stepper shakes and runs erratically when I send commands via a g-code interface.
I'm sure that for many robotics or CNC projects you have needed to extend these wires. What have you found that looks clean and works well?
Any suggestions would be appreciated.
