RAMBo Malfunctions Due to Bed Power
This is in relation to code ticket T8411. I was asked to breakout the RAMBo issues that we have documented by the type of failure the board encountered, as well as to include a bit of additional information on each individual case. I have added everyone that is subscribed to the other ticket to this one as well to try and keep people in the loop. All Bed Power related RAMBo failures are listed below, please let me know if there is additional information that would be helpful.
Ticket ID: 193,623, RMA13336, Original SO# 101-0000041-6577001. Bed Heater Power Cable and Port on RAMBo were charred.
Ticket ID 81,753, RMA13403, Original SO# SO103166. Bed wouldn’t heat tested resistances on all wiring and continuity of 15Amp fuse, found no indicators of anything amiss. Let him know this looked like a RAMBo issue. He replaced RAMBo and experienced the same issues. One of the LED’s on his RAMBo doesn’t light up the way it does on his other functional printer. It was suggested by Brent that we check their PSU so this might not be RAMBo related. We can update with additional information once they have checked PSU.
