I want to add a moving nozzle wiper base to a delta printer. I have an idea of having a stepper (6th — as this is done for dual extruder) to have a moving wiper platform on the side of the bed and have it be in sync with some gcode trickery with the part height (roughly). That can be accomplished with configuring it as a 3rd extruder with no temp or heater as it's just an extruder, then have it move linearly along the z-axis, but I need to have it home and respond to G28 — or possibly a custom command if that's not possible until it hits a limit switch. Can this be accomplished? Basically run an extruder until a limit switch is triggered?
