Hello, I recently purchased the Fluson I3 Dual Extruder Plus touch LCD. I was able to properly assemble the printer (even with very VERY lacking instructions). However I am stuck with the firmware. I want my printer to be able to Dual print, Thats why i bought the DUAL extruder. but the firmware came pre-loaded with only a single extruder. I have installed arduino and compiled the chimera dual extruder marlin.ino file. However I get an error saying “an Error occurred while uploading the sketch.” I have selected the correct com port however I believe that the mother board is incorrect and I dont know which one to use, or really where to go from here. ANY help would be highly appreciated :smiley:
