@deckingman I appreciate that was more of what I was looking for. I am aware of the risks and am not worried about that. Ill try tweaking around with the parameters more in the upcoming days
As a long term user of Duet products, I distinctly remember the events which led up to the introduction of heater fault protection. IIRC it was a user who posted on the RepRap forum that his heater cartridge had fallen out of the hot end onto the printed part. This meant that the hot end itself started to cool which was detected by the sensor so the heater got hotter and hotter. Fortunately, the user was close to his machine so no major damage ensued but it could easily have resulted in a fire.
I these days of litigation, that could have been bad for Duet as a company. So I have some sympathy with their position that heater fault detection should not be disabled. As a retired engineer, I prefer mechanical solutions so I design my hot ends so that a heater cannot fall out, and never use over powered heaters which could reach dangerously high temperatures if a MOSFET failed. So I'm comfortable with using wide fault detection parameters but for the reasons given, the Duet team could never condone it.
