Replaced PICA - now X-Axis won't move


I snapped a PCB trace on my original PICA and ordered a new one.

I received my new one and began setting it up. Unfortunately, I’m not able to get a motor to move on the X-Axis socket. I’m currently troubleshooting.

I’ve tried different motors, known working stepper drivers, tested the electronics on the y-axis and they worked.

Any tips?

I’m flummoxed.

I’ve considered moving the X-Axis to the E1 socket, but I need to figure out what pins those are.
