Hey!
recently I bought a ramp kit for my wanhao because te original bord fried itself. so I wondering: can I connect my original screen to the ramp kit without a adapter(my screen only have one cable, its the original screen)? and if a can how? and when how to I later load my gcode to the board? and if you have som tips and tricks I would really appreciate it!
have a nice day, happy printing!

You probably can if you can re-wire it. You will loose and card functionality since most ramps LCD’s have the SD card on it. Wanhao used the SD on the melzi so there isn’t one on the LCD.
