Ender 3 v2 X axis only moves in one direction.
I recently bought an Ender 3 v2 and just finish assemble it. However, just before I do the test print, I find the X motor only moves in one direction. It can only move to the home direction no matter how I change the moving position settings.
I followed the troubleshooting guide, switch the X and Z motor wire at the motor side, the X motor works no problems. After that, I switch the X and Z motor wire on the motherboard, still, the X motor only move in one direction. Therefore, it shouldn’t be the problem of motor or wire and consider I have the V1.02 firmware, not the problem of software as well. I think it’s something wrong with the motherboard.
So what should I do?
