I designed this for my own use, for use with in a CNC PCB Drilling Machine then in my New CNC Machine, which is a lot better than the first. I wanted to keep it simple, with few components. Its the bare essentials, just 3 Axis, STEP and DIRECTION for X,Y,Z.(6 inputs) No ENABLE or limit switches. There is the option to to toggle a timer that turns off a motor automaticly after its stepped. That allows for current limiting devices to run cooler and require less power overall. Its been designed for 3 Unipolar Stepper Motors.(5 & 6 Wire) And has been tested, and works great with KCAM.
Designed to control high-wattage motors, up to 20w per phase with no addional parts, but upto 40w per phase with some minor modifications.
