Haha awesome! My buddy had the same problem with his $5000 printer. He'd been calling tech support for over half a year, and their only way of solving the problem was replacing all the electronics. I came over one day, noticed it only works on some parts of the bed, and figured it was a broken wire within the same day. Depending on the position of the axis, the wire would either connect or disconnect (like flexing headphone wires after they broke). I'm glad you found the issue on your printer 🙂
Cheers.
