I have 2 CNC machines my old one and the one I am trying to get to work. The one with the problem has been in storage for 2-3 years. After all the testing I have done I think the drivers are defective. This is hard for me to accept, all 3 bad. I did take the parallel cable and moved it to my CNC and it worked fine ( both CNC’s have gecko drivers 250/250X ) This is why I think the configuration is correct. Not having a scope I looked at the speed and directions pins of the Gecko drive with a VOM, I can see some change as I jog the steppers.I have been waiting for Gecko to get back to me as how to check the drivers for proper operation.
I did check the input and direction wiring
Below is the results from the driver test
