I just picked up a micro plus for $20. I repaired the extruder motor gears and had it printing again. I clicked update firmware in the m3d software and it failed and now the printer is in bootloader mode. I've tried all the fixes on their site and used the spooler program to try to update it and nothing works. It always fails with firmware failed redundancy check.
I tried m33 and it won't detect the printer at all so I'm lost on what to do.
