MKS Gen L and RepRap display + Z axis travel

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. Aamcle

in configuration.h

//
// RepRapDiscount Smart Controller.
// [reprap.org]
//
// Note: Usually sold with a white PCB.
//
//#define REPRAP_DISCOUNT_SMART_CONTROLLER

remove the // from the #define

recompile and upload into the machine.

Make sure the motherboard is set to Gen_L ie
#define MOTHERBOARD BOARD_MKS_GEN_L

That is the current setting the reprap discount smart controller is the one defined.

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?


Thanks Alan.

I've no experience with MKS Gen L, but when I had to revers ribbon cable orientation for Smart LCDs, I always had to revers both.

Calling any MKS board 'genuine' is a punch in anyones face, they stole from.
