I recently purchased a 3D Printer from Goodwill and I can't get the Bed to stay up to Temperature. The Temperature gets up to about 40 Degrees and the LED on the Board goes out and doesn't come back on. The Setpoint is 70 Degrees. I tried to do an Autotune but it Timed Out. It looks almost exactly like the Han's Build on this Webpage: (Voxel OX - Extendable 3D Printer and CNC Platform). The Marlin Firmware Version is 1.1.0-RC3. The Menu Page says it is Jared's Bot. I would like to get some history on this Printer.
