      What are you actually trying to switch on and off? How is it connected?

      Hey,

      I try to switch on and off the welding torch. This is usually a hand triggered machine with a microswitch. There is a 12V circle and if this is closed, the machine "fires". I plan to go with 12v-Duet-controlled into this circle to start and stop the welding torch.

        I think https://duet3d.dozuki.com/Wiki/Gcode#Section_M571_Set_output_on_extrude should meet your needs.

          maybe you are looking for CNC mode?

          Maybe I'm looking for this, I don't know 🤪 but I'll check it, Thank you!

            I think that's it, thank you very much! 😊 I'll try it tomorrow!

            Are there a few words you can say about

            • how to know which pin is which number? In pin out grafic I can't see this, right?

            • which pins I could use? When I take a look to pin out, I'd say there are only the pwm fan output usable? Or are there some more?

            Thank you!

                  Hey together,

                  that wasn't succesful today...

                  I don't get a clear signal out of the board, and I can't find a mistake... Maybe I don't see something or do something wrong?

                  I try to geht 0/1 out on pin 64...

                  Like this:

                  is only for checking, if the extruder rotates, if I can get a signal

                  ; Custom settings are not defined
                  
                  M571 P64 S1
                  

                  is that the right way to use M571?

                  Which voltage I would measure, if it would work? 3.3V right?

                  I tried using pin 20 before, like here https://forum.duet3d.com/topic/7822/m571-to-turn-on-fan-0-everytime-the-extruder-is-started/3 but I dont want to get a pwm signal. If i write

                  M106 P0 I-1
                  M571 P20  S1
                  

                  I'd get a constant signal, right? But it doesn't work, too...

                  Or is writing M571 in config generally wrong? 😵

                  Thank you and have a relaxed day!

                  PS: wanted to correct some words and now its spaaam 😢

                    Using pins gets a lot simpler with RRF3 and based on your config.g it looks like you're still using RRF2. Check your firmware version with M115.

                    If you still have access to DWC. Upload these 3 zip files, one at a time. Don't extract them. Reboot after each.
                    https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip

                    https://github.com/Duet3D/RepRapFirmware/releases/download/3.2/Duet2and3Firmware-3.2.zip
                    That will get your firmware and DWC up to date.
                    https://configtool.reprapfirmware.org/Start
                    For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.

                    You can learn about how pins are defined and named here:

                      Thank you for showing me the way to make a safe update! I was a little bit scared to crash my system when i upload a wrong file from github 😕
                      but it worked perfectly!

                      I have now firmware version 3 and I understood the "new" pin names, but I dont have succes to get a signal with M571...

                      ; Custom settings are not defined
                      M950 P0 C"fan0"
                      M571 P"fan0" S1	
                      

                      this above doesn't work...

                      ; Custom settings are not defined
                      M950 P0 C"connsd.encsw"
                      M571 P"connsd.encsw" S1

                      ...doesn't work...

                      is it generally the right way to put M950 and M571 in the end of config.g?

                      Or should it be in the beginning of gcode?

                      I think I started print aboout 100 times now and I really don't now what to try now 😐

                        M571 P0 S1 without the quotes around the 0 should work I think

                          Hey, not atm...

                          Only

                          M571 P"bedheat" S1
                          

                          is working.

                          But no problem, I ordered optocoupler now for 24v and get other pins working I'll try another time.

                          Thank you very much for your help!

                            Ah sorry, when I was looking at it bleary eyed this morning I mistook the command.
