The only other thing that I can think of is the Driver wiring from the board to the driver. the driver has 4 wires going to it. yel, gray, red and black. from what I could tell from powering the mill up before I removed the onboard pc, the yellow and Gray are step and direction. I assumed that the red and black were 5v and G. I have the c11 board jumped so the common on the output is +5. I wired the red to that and the black to the ground on the output. I am assuming that since I am getting one step, my wiring is correct. May not be the case. From reading specs on another driver, maybe the red is an enable and the black is a common ground??? Maybe I need to change the jumper back to - common and connect black to that. Any ideas?
