Nozzle Auto-Cleaning Mount for Ender 3 S1 and Similar - Bambulab A1 Silicone Wiper

Description

Added an adapter for Bambulab A1 silicone nozzle wiper made to install on the bracket.

It uses standard Bambulab A1 silicone wiper. Simply print this variant, screw it on the mounting bracket and use the adhesive side of the wiper to mount it on the support.

 Contrary to the original model in the brush variant, I designed the part to be installed along the X axis, in order to use the max excursion/movement of the nozzle and to maximize the debris removal.

Clean Nozzle Macro

This is an example macro I use for this version.

Very similar to original one suggested, but it uses a little lower speed and 20mm movement along the x axis.

As always, do your tests and adjust youx/y/z values accordingly.

description: Cleans the nozzle by moving between X=235 and X=255

   G1 X{start_x} F{wipe_spd * 60}           ; Return to X=242
 {% endfor %}
 # Lift the nozzle after cleaning
 G1 Z{start_z + lift_after} F1500           ; Raise the nozzle by 10 mm
