  • The unknown commands are no problem. Server ignores them on further occurences.

    Problem is that heater in firmware fails and then firmware stops executing any commands. So once you solve the configuration it should work. But can‘t say how to reconfigure prusa firmware for new extruder.
  • well what should i do when the thermistor is a 100k and i cant figure out what should i change in the firmware because i am new to this whole firmware and 3d printing stuff, my 3d printers original extruder got jammed and i had to buy a new one and it has not worked after that
  • Don‘t know marlin good enough but that it shows at startup could mean there is temperature reading from beginning. Mean a broken wire, not connected to right pins, ...
