Hello all, I've learned a lot over the past couple of hours on how to upload firmware and such to support a Full Graphic Smart Controller. Firmware side of things I believe I have down but I'm having an issue that I can't find any information about. I have purchased this board [3D CAM] Full Graphic Smart Controller LCD Display for RAMPS 1.4 RepRap 3D Printer Electronics (128 x 64 display with SD card reader) https://www.amazon.com/gp/product/B00THZK5JU/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 With my controller unplugged from the board my printer will connect to my computer via USB. As soon as I plug in the smart adapter to the board my USB connection closes, meaning I can't upload the firmware with the controller already plugged in. I've edited the firmware (commented out #define REPRAP_DISCOUNT_SMART_CONTROLLER, uncommented #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER, and included the U8GLIB library), uploaded it to the printer, connected the controller but nothing displays. I have verified that EXP1 and EXP2 cables are plugged in correctly on both sides. Any ideas?
