I am just finishing a build of 3 printers, issue happens on all 3.
When I plug in any of the 3 limit switches it blanks the screen. They are normally open limit switches with factory made cables that fit to the mks Gen l v1.0 board, ebay purchase. Tested them with a multi meter for function and all good
Endstop configuration is set to true.
I have the board now just plugged to the smart controller and to computer to eliminate other connections, no change.
I have this firmware flashed to another printer of the same design and all good.
can anyone help
