      @noblebran you're best of tuning using T0 as the PWM power will be adjusted automatically to take into account whether the fan is on or not

        @jay_s_uk said in PID Tuning:

        M307 H1 B0 R3.539 C260.4 D14.22 S1.00 V23.1

        I had that in my config already, that is why I am so confused...

            Still after all the tuning, I am running the T0 as mentioned and look at this graph. I have seen literally no changes.

            Crazy, huh???

              @noblebran what type of hotend are you running? thats stupidly fast heat up
              is your config.g correct for your thermistor?

                @jay_s_uk its all e3d volcano, just replaced everything with this build. Granted it is extremely warm and humid where I am right now.

                This is what I am using for the thermistor:

                M308 S1 P"e0temp" Y"thermistor" T100000 B4138      ; configure sensor 1 as thermistor on pin e0temp

                I believe that is correct?

                  @noblebran if you're using an E3D thermistor, no

                  M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.060000e-8

                  Can you confirm what you purchased?

                    I do not have the e3d thermistor then. It is just a regular type k thermistor. I will order a new one, but I ran it on smoothieware for years and never had an issue. odd I how I don't have a problem now, I am buying a new block that allows the use of a cartridge but the one I have now isn't big enough for a cartridge.

                    Do you know of anyway to compensate or reduce the power to the cartridge to allow it to heat up less?

                    The cartridge is 12v also, not sure if that matters. I would think if it is 24v (set up that way) wouldn't it burn up?

                      Do you mean type k thermocouple?

                      Yikes, yes it does. It looks like you're running a 12v heater at 24v. Hence the insanely fast heat up. DO NOT DO THIS. Replace the heater with 24v immediately and don't use it until you do.

                          Can't believe I overlooked that!
