    Just getting around to turning on heaters on this custom build...I'm using a filastrude volcano tip with their supplied heating element and thermistor.

    I was getting heater faults because of slow temp rise so I tried an M303 but that crapped out around 100 degrees C and said that it was cancelled because it did not meet the desired temp.

    This is my first outing with these types of heaters so I'm a bit lost. I have the extruder heater on E0 and the thermistor on E0. I have a fan wired up but I disconnected for now because I wasn't sure if it was a factor.

    I'm running the Duet at 12v currently.

      @ajlapp said in M303 failure and other heater problems:

      M305 P0 X151 T"J"

      Where did you get T"J" ? Are you sure that's the thermocouple type?

        That’s for the bed...yes it’s correct and it does work. I haven’t tried the bed heater yet but I know the thermocouple is working.

        For the extruder heater I’m now thinking that this is a power issue...the heater is likely a 24v unit...so I probably just need to juice the board voltage.

        Maybe?!?

          If its Volcano, then i bet the heater and termistor are from E3D. If so then:

          1. Make sure heater is for 12V and not 24V one. You can measure resistance of it, 12V one have 4-5 Ohms, when 24V one have much more (10+ at least).
          2. If its correct heater, then make sure its connected to heater block tight so contact between heater and block is good.
          3. Configure your termistor correctly. E3D uses Semitec 104GT termistor, so your M305 P1 T100000 B4388 C7.060000e-8 R4700 should look like this.

            It’s definitely a 24v...so I’ll update that and my thermistor info.

            Thanks.

              Working! 24v and the thermistor line in config did the trick.
