Unfortunately mine caught on the side of the bed and pulled the thermistor wires out so i will have to replace that completely. I would have though the crash detection would have stopped it but it kept trying to print while the end of the nozzle was off the side of the bed.

Failed to capture the error message because I shut the machine down in a panic.

Anybody have any tips for steering me to a diagnosis / fix ?

Thanks in advance !
