Y end stops not reading during homing
Posted: Mon Oct 14, 2013 9:47 pm
Recently I decided to use the Repetier Firmware and I almost have everything working, though my Y hall-effect end stops are not stopping the Y gantry. On my LCD read-out the Y-end-stops read "on" when the magnet goes over them (the light on the chip turns green too) - so its definitely detecting them, however the Y gantry just keeps on going and crashes. My other end stops are working fine with no problems. I think it may be an incorrect value in my firmware. The Y end-stops were working on my previous Marlin firmware, so I don't think it's a hardware issue.
Here is my code:
