      I've got a delta printer, nothing connected to the extruder endstop. But in the machine properties the extruder endstop is listed as hit, which means I can't extrude anything.

      How can I invert or disable the extruder endstop?

        Ok, I just created a plug to connect the two outside pins of the Extruder endstop together. That way it's inverted...

          disable filament out sensing on the extruder and that should clear up the issue:

              By default, extruder endstops don't do anything. The usual reasons for not being able to extrude are:

              • no tool selected (so it doesn't know which extruder drive to use);
              • tool not heated and cold extrusion not enabled.

              In either case there should be an error message on the GCode Console page od Duet web Control.

                Yeah, seems like it. Initially I was just confused of the endstop being listet as "hit", so I thought I could never print that way. Therefore I never even tried to extrude or print anything. I thought the "safest" way to get a print going was just to create a "jumper" for that endstop.

                I'm thinking about disabling the cold extrusion prevention, but I'm not sure if I want to do that, because it's kind of a safety feature. Although it probably doesn't cause much harm to cold extrude. I don't have a geared extruder so it will just keep slipping and losing steps until I can shut off the printer noticing my fault 🙂

                  @adras I would leave cold extrusion prevention turned on - that way you get an error message if you try to extruder with the hotend cold.
