Solved Auto leveling limit switches are not working.

My auto leveling limit switches are not working and the head of the printer is going down to far and impacting the bed! Everything was working before this and I printed a calibration block perfectly and now something messed up. Anyone have any ideas how to fix?

 

Send M119 in terminal. Check all your connectors and make sure the switches report a closed circuit when you lift then off the carriage

 

you can send m119. it will report switch position, then you can move around depressing (releasing w/e) 1 switch at a time to ensure all are working in both positions.
they likely are... but loose wires are part of the fun.

 

M119 reports open whether it's depressed or not. I can't find any lose connections.

 

If one or the other switches is not pressed and it still reports open there's a lose connection somewhere that you need to find.
