      I just finishing a HEVO build and my heater has been inconsistent the few times I've tried to heat my hotend as I was building this printer. Now that I have the printer completed it no longer heats at all. What do I need to change in my config.g file to use the E1 heater port as the tool 0 heater source?

        Are you running RepRapFirmware 2 or 3? Send M115 to check, and post your config.g file

          I got it figured out and the E0 heater port on the board works. I did not know how to turn on the extruder. This is like learning a new foreign language. It's all new to me after doing several other printer builds with Marlin and Klipper. It seems kind of weird though that the bed comes on when I turn the temperature up but the hot end does not. It could be a little more user-friendly in my opinion.

            Most other firmwares don't really understand tools, only heaters. We try to make allowances for new users in RRF, like selecting a tool automatically if M109 is received with no tool selected; but we can't make too many assumptions because RRF is used in a very wide range of machine configurations.

              Okay now I am getting a heater error a minute or two into the print and my wiring is fine, plus I have a newer thermistor and heater cartridge. How do I remap the heater to use the second hotend heater connection on my Duet Maestro board instead of the first? I did a PID autotune too. I changed the thermistor type from what it was from B4138 to B4725 for my Semitec 104GT2 thermistor.

                That doesn't necessarily indicate a hardware problem. Have you read https://duet3d.dozuki.com/Wiki/Spurious_heater_faults_and_how_to_avoid_them ?

                  I am using the latest 2.0x firmware from February. I will adjust the heater timeout to see if that will work. What is it by default and where is that in the config files? I see that the M570 S120 gcode command will set it too. I do not have a strong fan and I get a heater error with the fan off.

                  If you could let me know how to remap the heater connection hotend 0 to hotend 1, I would appreciate it too. I was not able to find that doing a simple google search. I've done it before in Marlin.

                    Look for your M563 command in config.g and change H1 to H2 in that command. You will also need a M305 H2 command in config.g similar to the M305 H1 command that is already there. Move the hot end thermistor to the E1 thermistor connector too.

                      These are the two lines that I changed in config.g and I'm getting an error, Temperature reading fault on heater 2: sensor open circuit, with my Heater 2 temp showing 2000.0 degrees 😄

                      M563 P0 D0 H2 F0

                      I move the thermistor connector to the thermistor 2 connection on the board.

                        This is what I have now under heaters:

                        ; Heaters
                        M305 P0 T100000 B4138 R2200 ; set thermistor + ADC parameters for heater 0
                        M143 H0 S120 ; set temperature limit for heater 0 to 120C
                        M305 P1 T100000 B4138 R2200 ; set thermistor + ADC parameters for heater 1
                        M143 H1 S280 ; set temperature limit for heater 1 to 280C

                          Please confirm which Duet you are using. If it's a Maestro then it has 4 thermistor connectors in total, so please make sure you have selected the right one.

                            I tried the one right next to the one that was working for E0 and the third one that is close, diagonally from E0 that worked. I have a Maestro.

                              It's the one labelled E1 Temp, next to E0 temp that you were using before. the third one in that area is labelled C Temp.

                              You can use the E0 Temp connector instead if you add parameter X1 to your M305 P2 command.

                              BTW that M305 P2 command is probably wrong because the B4725 parameter is normally used with a C parameter too, to model the hot end thermistors shipped by E3D.

                                After connecting the thermistor to E0 again, I added X1 to M305 P2 and it now has a reading of room temperature. However when I go to heat it up it will not heat and I get the heating too slowly error. I did change B4725 to B4138 like I had before.

                                    Are you saying that it's not heating up at all? Does the red LED next to the E1 Heat output light up when you select tool 0 and command it to heat up?

                                    Given that you couldn't make it work on E0 output either, it sounds to me that either the heater cartridge or the wiring is faulty.

                                      I'm on my second heater cartridge. The first one was a new 24V one from E3D and the second one is a Trianglelab one. There is not much print time on either and the first one from E3d went bad.

                                      I noticed that the wire connectors on my thermistor plug to the board was loose. I pressed the connectors in tight but I did not rewire the plug like I should have. I will do that later. It started working again but now it won't go over 211 degrees celsius. I have my print set for 225 and it is stuck at 210 or 211 and it has not timed out with an error surprisingly. I did not change the heater timeout either. It finally did give an heater fault error after a few minutes of not getting up to temp.

                                      I did not check the led but I will the next time. I would like to get the heater remapped to E1 port on the board if possible to eliminate that the E0 port is bad. I don't understand why I had one cartridge go bad and then another if the second cartridge is bad.

                                        It seems to have a problem at higher temps but only while printing. I just cranked it up to 235 and it held firm there while the printer was idle for a few minutes. Maybe the vibrations are affecting my weak thermistor connection to the board.

                                          I found the problem. It is because of my fan being on! I only have a single fan on the hotend, and the hotend has a sock on it! I turn the fan off and the temp shoots right up. I know that I should have known better but on my 7 other, home built, printers I never had this problem, especially when using a single fan for cooling and a heat block sock. The only difference with this machine is that it's 24 volt, including the cooling fan, versus 12 volt on the other printers that I built.

                                            Did you run your PID tune with the fan on? That can help.
