Here's a video of how it's acting now:
It used to move up the z axis, move left on x, extend the probe, move to the middle and click the endstop.
Now after it extends the probe it moves right on the x axis, retracts the probe and then plows into the build platform. At that point I have to turn off the printer.
It used to work like marty's sequence:
I'm not sure exactly what I did. I remember that after the last print, the probe got stuck on the build platform binder clips and then after that, the z-axis starting position seemed too high so then I tried to adjust the z-axis offset by 2mm and then this was when I started noticing the problem. Any ideas?
