I started to flash Marlin (MPCNC813MRAmbo_GLCD_T8) on my mini Rambo. I bought the Rambo as a Kit from Amazon with a 2004A LCD screen (https://www.amazon.de/gp/product/B07GZNW64R/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1). But after flashing the LCD don’t show any information, just a blue screen.
I tried the following LDC´s to define:
// RepRapDiscount Smart Controller.
// Note: Usually sold with a white PCB.
and the default “full graphic LCD”.
Someone know this problem ?
