Hi RepRap-Community
So I recently bought an LCD 12864 for my DIY CoreXY printer. Today I hooked it up to the Ramps 1.4 board, installed the Marlin firmware and got it to (kinda) work. The only problem is, that after a time staying on the whole screen shifts to the right and comes in on the left side again. It's probably hard to understand but i think it's a hardware problem, not a software problem, because when i reset the Ramps board, the LCD restarts as well but the issue still persists and the Marlin Logo is cut off on one side and reappearing on the other.
I have searched for other people that had this problem but it seems like I'm the only one.
Thanks in advance for the replies
