Help!

Every time I try to home any axis (or start a print job for that matter), I get this error when the axis arrives at it’s home position. I have no mechanical endstop, using a MKS GEN1.4 board.

Below here is my config and my printer settings in Repetier Host. If anyone is able to help I’d be eternally grateful!
