Genuine MKS Gen L BigTree Tech - Discount RepRap Smart Controler. Marlin 1.1.9 BugFix release. I was getting nothing on the display not even the back light so I've followed one of the "fixes" and reversed the Number 1 ribbon cable connector. Now I have the blue back light and white rectangles where the text should be but sadly no text. What's next? I've seen references to enabling a different display which one should I choose? Will I damage anything if I work in order through the options Marlin offers? Moving on, I have X, Y and Z moving but Z does not stop when the end stop is triggered manually although the LED on the end stop pcb does illuminate. The Z end stop is plugged into Z min and defined as Z min in Marlin although it is inverted. Any Advice much appreciated. Thanks All.

I've read that there is a incompatibility between genuine MKS Gen L boards and some clone controllers and I unfortunately have a clone.

Any idea whats up with the Z axis?
