K40 with cohesion3d controller.
I recently took my k40 apart to try and square the gantry. I accidentally put the ribbon cable in backwards and obviously my x axis wouldn’t respond. So I took it apart again, put the ribbon in correctly and put it back together. Ran a few jobs to ensure everything was moving. Homed the machine and everything worked well. However when I went to cut the machine seemed lost on where the laser head was. Rather than coming 6" forward to cut and then work back. It came out about 2-3" and then worked back. Causing it to try to force its way past the back of the machine.
I can move the laser through the software to where it should go. I only have the problem when I’m trying to cut. I’m sure it’s not a software issue, as everything was fine (minus the gantry/axis issue). Before I took the machine apart. I’d assume that the ribbon cable isn’t directional, and it has to be side a to board side b to motor. Is it possible that I damaged the board putting it in the wrong way? I didn’t power down the board when I took it apart. Could I have shorted the board?
What could be causing this?
