      Hi, I am working on a metal 3D printer that extrudes metal paste via a piston type extruder. I have bought the Duet 3 6HC, a 1XD external stepper driver and thermocouple daughter boards and so far so good. My last step is to add limit switches for the piston type extruder (electric linear actuator). How can I define the limit switches in the RepRap firmware? I don't need anything fancy, I just want the extruder to stop moving in the direction corresponding to the limit switch triggered.

      Thanks!

        Extruders usually don't have a limit, but you can use external trigger-macros to do the job.
