Lcd problem when connected to ramps

Post by mava70 » Tue Nov 24, 2015 4:11 pm

Hello I have had a gt2560 with 2004 lcd. Gt2560 is brocken so I swapped with a standard ramps/2560. Ai have to buy a standard lcd adapter on ebay for connecting 2004 to ramps. When I connect the lcd ribbon
Printer stop working and on pc I see a mintemp error reached. Lcd doesn't work but is correctly connected.
If I disconnect the lcd printer works normally.

Any idea?

Yes the firmware is correct your firmware for rakps board prusa b and it works very well when lcd disconnected.
Lcd is correctly configured in config.h same as gt2560 firmware
