      Hi, I am developing a few custom 3D printers as part of my research, one of them being asphalt (first paper here - https://www.sciencedirect.com/science/article/pii/S026412751830724X)

      I have been through so many boards over the years and it looks like the duet is the best one but using the extruders I have developed throws up so many heater errors that require a full reset, even with calibration. Also part of my work will need to modulate the temperature as it is printing which the Duet also doesnt seem to like.

      How can I disable the heater protections on the board? is it possible?

      many thanks

      Rich

        You can reduce the sensitivity of the heater protection system, see https://duet3d.dozuki.com/Wiki/Spurious_heater_faults_and_how_to_avoid_them. Or if you build the firmware from source code, you could disable it entirely.
