    Hi, I’d purchase a Geeetech I3Pro W used, the person who I bought from, never used a SD card on it. Now, I will like to use the SD card to do some stand a long printing without a connected pc. I have read that you have some problem with some supplier, about the SD card slot on the display. I will like to know if this display will work for my I3Pro W printer and also if this card will solve the problem that the display saying “Card Inserted” and inside the menu saying “No card” will be fixed. Thanks in advance

    • Jocelin Jia | 10/29/2018

      1 this can use on PROW 2 if no card problem,you can change a sd card to see if the sd card module is working well,

    i have a display that looks exactly like this and the adapter. i believe it is correct because i can turn it on and see the display show my printer settings, i cant get the encoder and button to work at all though. Also the sd card is not discovered.

    I've bought Smart Controller LCD2004 Display and the adapter for Ramps 1.4 and it seem to have some trouble: - there is no information on the display, even if I tune the contrast with the little adjustable resistor on the rear of your board. Is it full compatible with reprap discount smart controler, or is there some specific tune to do ? Is thère a special setting in the Arduino-code to set or is it full compatible with a "s
