      What I have is an ultra cheap switch. Does not look like anything is adjustable ( other than a bend here or there ). I don't think the switch setup is wrong, I would expect the config is right or not right. The switch works, just flaky. I don't think the wiring is exposed to any noise that could cause a problem. Filament always seems to jam up inside the box trying to get it to feed through. I will suspect that the switch is acting up.

      Any good not mechanical switches, I've seen some IR ones, do they work with transparent filament?

      Thanks

        What I was suggesting falls under 'a bend here or there'. While a flaky switch is certainly possible, I would try 'adjusting' it .... it worked for me and doesn't cost anything to try.

          When I briefly used a simple mechanical micro switch with a level arm for a runout sensor I found that even when the path was very constrained the level arm would eventually lose contact with the filament enough to release the switch. If I changed the enclosure to be tighter the amount of friction was too much and it would eventually jam. In the end I changed to a switch with a wheel on the lever arm to allow it to roll. This worked better, but I eventually abandoned it as well.

              I weigh the spool before I start the print.

                What if your print takes more than a single spool ?

                  Well if it takes more than my current print I choose a spool that has enough. If the printed needed more than a full 1kg of plastic I'm not sure what I'd do. It's never come up.

                    It's surprising how quickly you can go through a 1 kg spool when printing with a 0.8 mm nozzle and a Volcano heat block. When I print large objects, I print LARGE objects 🙂
                    Anyway, I have not had an issue with a simple microswitch without a roller.

                      I do have a Duet laser sensor and was thinking of maybe doing one of these two mods
