Hi,
I added dual end stops to my ramps set up which was very easy and a great decision! All is working perfectly except the Z axis.
I can home x and y individually fine and all works. I can even home Z and it seems to operate correctly. Touches the plate, retracts and touches again. All seems normal…
However, a few moments after homing the Z axis I get a printer halted kill called, please reset error!
I have checked all the wiring on everything and all seems correct, I have even tested just shorting two wires directly together to simulate Z touch and get the same issue. I am starting to think it is either firmware related or possibly a faulty ramps board?
Any ideas?? thanks
