i currently testing my mpcnc. im using ramps v1.6, tmc2209, and full graphics lcd. the lcd does light up but doesnt display anything. this is a new ramps, mega, as well as lcd, because i have fried the old one by plugging both the psu and usb. at first i only change the ramps and mega and keep lcd. it only shows blue no text. ive tried to put the wiring upside down and swap exp1 and exp2 but it still doesnt work. now ive replaced the lcd as well and still the same. im using mpcnc ramps dual marlin config and only changes tmc2209
before the short, it works fine
im able comnect via pronterface
Check the contrast pot on the LCD. It is possible the screen is just washed out
already tried that. still didnt work
