Hi,
My first post here and directly a question.
I've got a Prusa i3 printer and used to use a ramps 1.4 board from gadgets3D. But I had some ideas about printing with 3 extruders so I decided to buy a RUMBA board from geeetech. Since I still had the ramps 1.4 with a 2004 lcd smart controller I wanted to use the lcd for the RUMBA board and there came the difficulties. I found out that I had to plug exp1 plug in the exp2 port and vice versa and also turn the connectors 180 degrees.
But I still have a problem and that is that when I plug in a SD card in the smart controller the whole machine freezes. Are there any tricks I'm missing?
