I have lost a couple prints over time to this issue. I would resume the print and the Print head would just move within a very small space and not the correct size of the part. Ends up making a blob. I can see the movements are there but scaled down to 1/100 of the size.

Has anyone else experience this and was it recoverable or just need to do reset and lose the print?

You did not enable the sensor

Thanks. That's what I figured. I am switching to silcone heater and standard setup now.

I have a heated bed with Gnd 12V and thermistor wired in the same circuit and I am concerned that it may short and fry the board. I am using the Duet 2 Maestro Board.

Would this be safe to wire up the 12V pin 1 and 12V pin 2 Ground to HB power and then the 5V with the Thermistor to the board thermistor plug?

Additionally Could I add something to protect the thermistor ground from the 12V and current for over-voltage and current protection (such as a polyfuse (or normal fuse) and Zener-diode?

I have attached what someone did for the HBP spec below.
