I have one of these boards and when you combine it with a stepper driver it controls stepper motors very well thru Mach 3. I am trying to figure out how to exactly wire the E-stop. There are directions but they don't seem to work. My question is, does anyone else have this board and have they hooked up an e-stop properly and how ??? Thanks Steven
Wow I figured it out. I was connecting everything ok and had setup everything ok in Mach3. I thought it was using the 5volt power from the USB to do the test from pin 10 to the ground but I was wrong. I needed to supply 12 - 24volts from the power supply back into the board so it could use that as a test. Now it works perfectly, I think I need to make a video on this board.
