So I have read this question, Connecting (Anet A8) 2004 display to MKS GEN L.

That looked so easy, so I rewired the connectors and switched the VCC and GND pins. In the Marlin firmware I disabled the MKS GEN L display and enabled the ZONESTAR_LCD and ULTRA_LCD.

Yet when I run the printer, I only get the fully white rectangles. Is there anything else I have to do?

I have a compilation warnings now, because the ZONESTAR_LCD redefines some of the pins that ULTRA_LCD sets, but I guess that is ok. Could it be caused by still including the U8glib library? Do I have to also remove some constant regarding this?

Ok guys I got it! It really was just what is the answer in the other question (Connecting (Anet A8) 2004 display to MKS GEN L)!

My problem was: I used jumper cables and some duct tape to hold them together ... and the only issue was, that I didn't insert it enough. I got mad today and just pushed them really hard more into the AUX2 connector and it suddenly works!

  • Yeah, it's always a good idea to push the connector home firmly and fully. :-) I'm glad that you solved your problem. – Greenonline Jul 18 '18 at 22:54
