Fast shipping and well packed.However there is a contrast problem in my lcd display.I tried several times to adjut but visibility is just decreasing not increase.Another ıssue is when ı press the toggle switch to reach to main menu the lcd and also the menu selections are bilinking.Because of that reason it is imposible to control the machine settings. Best regards.

  • Raphael You just have to solder a resistance between 470 and 1k ohm between Pins 2/3 and it will work fine. I have posted a picture here: http://www.banggood.com/LCD12864-RAMPS-1_4-Board-2560-R3-Control-Board-A4988-Driver-Kit-images-p936768-q46549.html
