I have just installed a rep-rap LCD controller on my Printrbot Simple Maker’s Kit. Upon switching on the printer, the LCD beeps and flashes between two different screens, and does not stop.
I have seen that a possible solution involves attaching the LCD ribbon cables 180 degrees, but I cannot work out whether both EXP1 and EXP2 need to be turned, and in essence does that make pin 1 into pin 10 and vice versa?
Or has anyone experienced anything similar and have an idea on how to fix?
