Not sure where to begin, but I have 3 identical axis drivers that were working just fine. I was building a new CNC router and I needed 1 driver for test my build , so I took the driver from my {"X" axis and put it on a identical motor setup only on "Z" axis . I tried my machine out all was just waiting for the replacement. When new Driver of again same brand as I had , came in I put it on the newer machine. And put the one I took off of older CNC, and reinstated it back on "X" axis . Put setting back as they were prior to removing driver and loaded Mach 4. put machine in manual mode with Mach 4 and tried "X" axis and low and behold it would not work. Made sure "X" axis drive screw was not free with power on driver and all was well with that, put Enable pin to ground and that released motor so I could turn screw by hand. So that was good. So I swapped motor wires and with "Y axis and had "Y" axis driver control "X" motor and no problem , so that eliminated wiring problem with "X" axis so then I swapped only pulse and direction wires on my pmdx controller and had output of motion board's "X" output control "Y" axis again no issue, So that ruled out PMDX board. So I took the driver on "X" axis back off and placed it on new machine I was building but with a different motion board and that driver worked just fine. So I put new Driver On old machine put switches on driver where they needed to be and connected a know working driver back to my older machine, and same condition, no "X" axis movement. So I am at the end of my knowledge about this and have come to forum for ideas. Now remember wiring checked out and was verified by using "Y" axis driver and pmdx board. The know good driver was verified on new machine and works well but again different motion board. And what was good driver on "X" was swapped with new machine and works just fine. All motion pulse and directions outputs were swapped and worked just fine when controlling "Z" and "Y" but nothing works when "X" is connected to any driver I have tried. 5 of them all together and all failed on "X" and when swapped with "Y" then "Y" does not work and when swapped with "Z" then "Z" does not work. BUT ALL DRIVERS WORK WITH NEW MACHINE WITH DIFFERENT MOTION CONTROLLER.
