I have some problems with my electronics. I'm using ramps 1.4, arduino mega and LCD 2004. As you can see in the picture sometimes I got some garbage on my LCD. I have checked all the connections over an over again. I tried with 3 different LCD's but the problem still exist. I have also changed the LCD adaptor that one who is making the connection between the LCD cables and Ramps. It happends during the print or when the print is on idle. If it happens during the print, sometimes the printer goes crazy for a few seconds like it's printing weird lines and then come back to what it should print. And sometimes it's just blank.......Any suggestions will be appreciated. Thanks!
