I believe that I have the Step and Dir pins assigned correctly. From the x-axis driver, Dir - goes to pin2 on the C10, COM is 5V, Step - goes to pin3, and and so on for y and z axis'. In Mach3, I setup Step Pin# 3, Dir Pin# 2, enabled and both set at active low. In the wiring diagram I have for KL4030 with C10, the Step- goes to pin 2 and Dir- to pin 3 (reverse of what I have), but as long as I assign it to the right pin in Mach3 it shouldn't matter, correct?
