X axis motor not moving under RAMPS 1.4 test firmware (21 replies)

Hi everyone,

I am hooking up my motors and endstops to my RAMPS 1.4 board to test them out using the test firmware on the wiki, and I'm having issues with my X axis.

Plugging my motor into the X axis port causes my motor to not move at all. I then moved the motor and plugged it into the Y axis port, and it works fine.

I thought it might be a motor driver issue, so I swapped out the X and Y axis drivers, and still the X axis port doesn't work, but the Y axis one does, so not a driver problem.

I then thought maybe it was an endstop issues, so I swapped the X and Y axis endstops on the board and got the same results, still no movement on the X axis port.

I purchased this board pre-assembled, but I looked for any obvious issues with the soldering but it all seems ok.

Can anyone suggest any fixes or more steps I can take to troubleshoot this problem?

Thanks!
