Random Endstop Hit Error (1 reply)

Alright Reprap experts, I need your help. I am a total newbie, so I apologize if I am missing something basic here.

When beginning a build, I get a "Hit Endstop:Y" message on my LCD screen, and the build continues. I continue to get the same error at random points in the build. The screen flashes when it happens. It occurs whether or not the endstops are connected to the RAMPS board. Unfortunately, the build rehomes, and continues running offset to the original XY coordinates.

I am using Marlin with Ramps 1.4

Any and all help is appreciated.

Thanks!

Ken
