Hi all,On my first try after assembling my printer I had problem with the LCD display. There was some strange chars at the begining and after that, I had the MINTEMP error.Well, the problem with the LCD display was a bad contact between the Arduino board and the Pololu shield. Make sure of attaching the pin header deeply. After that, I had no problem with LCD but I continued having MINTEMP error.The problem related to MINTEMP was a bad contact in extruder connector. I noticed that because when I touched the cables and I powered on the printer, sometimes MINTEMP didn't appear.To fix that, I removed the connector and I soldered the cables directly (see image)Best regards,Jose.

HI, I had a similar issue with my printer. the LCD read gibberish and then I would press the encoder and it would resolve itself. Now the LCD has stopped working altogether. I tried some mysterious combination or resetting, powering down and reloading firmware and got it to work again, once, but now I can't remember what I did and it had blanked out again. The LCD will light up and it does make sounds when I press the encoder but it doesn't display any text so I can't get it to run through the set up protocols. I hope the board is not burned out. any ideas?
