My printer just started disconnecting mid-print. I have tried using different slicers, the USB has not been changed since I started using the printer, the fan is working on the Arduino and the printer acts great when it starts, but will disconnect at random points. I also have tried older versions of MatterControl to remedy the issue. I have noticed that the yellow/warm white LED under the stepper board will turn off and I need to re-set the arduino. When I do that; a green LED comes on and then the yellow/warm white LED will be on once again and I can then manually control the printer and start more print jobs. Nothing major has been changed on the printer (i.e. cable, boards, extruder, etc.). I have tried different settings in case it was a temp. override issue, but there is no way to predict when it will do it. It could be on the first layer or 1/8" up the print. I noticed in other message boards that a quick solution was (xxl lcd screen). I have the original RoBo3D, not the R1, but I do have all the necessary upgrades with exception to the arduino. Can I use the LCD screen with mine and where is the best place to get the correct one? If this will solve the issue, I have no problem getting one shipped immediately. Could it be that my arduino has finally given up? Thanks for any help available!
