Ender 3 S1 Nozzle Wiper
Description
I wanted to create the ability to start a print without having to observe my first layer on my Ender 3 S1. I recently bought an X1C and was inspired by it's method of purging, and cleaning the nozzle at the start of each print. This design uses the stock nozzle cleaner from an X1, combined with some custom start GCODE (below) to acheive something similar to a Bambulab printer's start sequence. My Ender 3 S1 is running Klipper, and I currently use Bambu Slicer. From my own use, this has greatly enhanced my Ender 3 S1's ability to start a print without any user intervention. Use my custom GCODE (at your own risk) to see some awesome results. Before running the GCODE, ensure that the wiper is adjusted so that it doesn't crash into the bed. I recomment mounting these parts with the printer off, then gently moving the Z axis screws with your hands to ensure clearance. Luckly, with the S1's design, the Z axis won't become unaligned because of the belt at the top. Happy printing and I hope this design helps someone as it did for me!
