      I have a 50w cartridge connected to a duet smart effector, to the H+ and H- input. I have tested the cables with a volt meter. I've also tried with a different cartridge. Here's my config and M122

      ; Heaters
      M308 S0 P"temp1" Y"thermistor" T118000 B3950       ; configure sensor 0 as thermistor on pin temp1

      M307 H0 B0 S1.00                                   ; disable bang-bang mode for the bed heater and set PWM limit
      M140 H0                                            ; map heated bed to heater 0
      M143 H0 S120                                       ; set temperature limit for heater 0 to 120C

        I don't know the ins and outs of the "smart effector".

        How does it connect to the 6HC board?

            And it also connects to "temp0"?

              @fcwilt pt1000 to temp_0, yes. It reads the temp fairly correctly +/- 1-2 degrees, but cartridge won't start heating at all.

                Have you run heater tuning yet?

                  @fcwilt Yes, but it fails, since it won't start heating at all. It works fine for the bed.

                    Well seems to me that problems must be:

                    • in the wiring
                    • with the board output

                    You say have tested the wiring.

                    Have you tried connecting to the out1 connections - with the appropriate changes to the **config.**g file - just to see if the problems line with out2?

                      @fcwilt out1 is the heatbed. I have tested out3, and still the same issue. It could still be the wiring, I'm just not sure how to test it other than with a volt meter. Maybe I've connected it wrong on the smart effector, I don't know.

                      https://docs.duet3d.com/hardware/smart_effector/smart_effector_v2_wiring.png

                      I connected the output from the mainboard to the ones circled in green. And HEATER to the heating cartridge in the hotend.

                        There is a problem with that diagram unrelated to your issue. Notice on the input H+ is shown as a solid yellow shape. On the heater output H+ is shown as a yellow/black shape. It means nothing from a practical point of view since heaters don't have polarity.

                        You mention that out 1 is the heated bed. So you are not using the actual bed heater output, out 0?

                        If you have tested both out 2 and out 3 then the problem must lie in the wiring.

                        What do you get when you measure the resistance across the lead ends that connect to the 6HC?

                          Nothing. It seems to be a poor connection/crimp. Not the first time during this build. I'll try redoing it. It was very hard, since I had to use thick cables for tiny crimps.

                            The connectors used for those outputs accept fairly large wires easily.

                            What size wire are you using?

                            What sort of crimp tool are you using?

                              @fcwilt You're right, the output side is fine, but the input on the smart effector is terrble.

                                  @velvia Tested the wires again, red to red and black to black, no problems. They are both whole.

                                    You mean to say they did not use the same connectors for both the input and output connections?

                                    That is not a good idea at all.

                                    You can always "cheat" a little. Short lengths of small gauge wires are not going to be a problem.

                                    So if you have the tools you could solder and heat-shrink two 50mm lengths (or so) of small gauge wire to the long large gauge wires coming from the 6HC. That would make crimping the small connectors much easier.

                                      @velvia said in Hotend temperature not rising at all:

                                      @velvia Tested the wires again, red to red and black to black, no problems. They are both whole.

                                      You need to verify the resistance across the ends of the two wires that would connect to the 6HC.

                                        @fcwilt Did that now and discovered the issue. Yet another poor crimp by me. It threw me off since it worked the first time I tested it. Now the heater works
