This is not an issue I have come across, is it possible the beaglebone control board got wet or otherwise damaged at some point? If this is the issue you could try replacing the beaglebone alone, or the entire control computer form labmaker. FIrst I would take it apart and look closely at the control board to see if anything is obviously damaged. If not, you could try connecting it to various other computers and maybe it will come alive, however, if not likely it is some hardware fault there that is not going to be easy to rectify yourself…
