Nozzle Auto-Cleaning Mount for Ender 3 S1 and Similar with Printers Bambulab wiper and steel brush (with GCODE)

This mount is specifically designed to keep your 3D printer's nozzle clean automatically. Built for the Ender 3 S1 and similar models, the design includes a cleaner inspired by the Bambu Lab system, but adapted and enhanced to work perfectly with this setup.

The design includes a printable cleaner, along with assembly instructions. Additionally, a GCODE file is provided to automate the cleaning process, reducing manual maintenance time and ensuring consistent, high-quality prints.

Key Features:

• Optimized design: The cleaner is tailored to maximize efficiency for the Ender 3 S1.
• Easy installation: Features a mount for quick assembly using standard hardware.
• Included GCODE: Simplifies usage with a ready-to-go automated cleaning file.

Includes:

• STL files for the mount and cleaner.
• Automated cleaning GCODE file.
• Detailed hardware list for assembly.

Hardware List for Assembly Bambulab Wiper:

1. Nozzle cleaner - Printable part included in the files.
2. PTFE tube - 12 mm length (can be slightly adjusted as needed).
3. Filament piece 1.75mm - 16 mm length (can be slightly adjusted as needed)
4. Threaded insert - M3x5x4.

Attention, creators and enthusiasts !!! 

If the Bambulab Wiper isn’t your thing, don’t worry! 🔧 I’ve got you covered with an equally functional alternative: the brush. 💡

Hardware List for Assembly Brush:

1. Set screw M3x3 - 2 Units, (OPTIONAL),
2. Screw M3x20  - 1 unit,  Button head cap,
3. Brush Mount - Printable part included in the files.
4. Steel Brush - 40mm length
5. Glue

You can use the same macro for the brush, just extend the movement distance in X. For example, x232, x245, and lower the nozzle a bit more.

G-CODE Print start 

# Nozzle cleaning with the cleaner from X=236 to X=244
M117 Cleaning nozzle... ; Display message on the screen
SWIPE START_X=232 END_X=242 START_Y=10 START_Z=5 WIPE_QTY=6 WIPE_SPD=200 LIFT_AFTER=10 ; Execute SWIPE macro for cleaning

Note: This G-code should be added to the print start (SLICER) sequence  before the purge line. 
 

The values X232, X242, and Z5 should be adjusted according to the position of your nozzle cleaner. Test by moving the printhead to approximate positions and modify these values accordingly.

• IF YOU WANT TO ENABLE THIS MACRO ON THE KLIPPER SCREEN, USE THIS G-CODE.

 # Lift the nozzle after cleaning
 G1 Z{start_z + lift_after} F1500           ; Raise the nozzle by 10 mm

Note: The values X232, X242, and Z5 should be adjusted according to the position of your nozzle cleaner. Test by moving the printhead to approximate positions and modify these values accordingly.

Happy printing !!!
