Just in case you haven’t tried it yet, go into the Utilities menu and then select the option near the very bottom of the menu to reset the printer to factory defaults.

If that doesn’t do it, it must be something with the thermocouple connection on the systemboard. A quick check on Youtube shows a few people having that exact problem, and all of them traced it back to the connection on the board.

On the Qidi Tech 1, the thermocouple leads attach to a separate two post quick disconnect terminal strip that in turn plugs into the logic board. It looks like the Makerbot uses a spring actuated terminal strip instead. Obviously I don’t have your printer in front of me to confirm this, but I’d bet money that the terminal strip isn’t putting enough pressure on the leads given how thin the leads are. If you have a Fluke meter that can read temperature, you can test the thermocouple to rule it out 100% (that’s what I did in my case). After that, strip off some of the insulation on the thermocouple leads that go to the logic board (say an inch), and fold it over two times to increase its width, then tin it so it doesn’t fray and gives you the best possible connection.

If that works then it’s definitely a flakey spring terminal strip. I have some of those inside a Hensel Porty light head and it gives me headaches every now and then. In theory those things work fine, in practice the connection is only as good as the spring inside the terminal strip.
