Automatic Nozzle Cleaning Brush - Ender 3 V3 KE/SE

prusaprinters

This is my version of an automatic nozzle cleaner set up. I tried the other models out there but none of them fit with the gridfinity side mounts or other side-storage style models.  Install is really simple. Just chop off the end of a cheap aliexpress/amazon brush and hot glue it onto the mounting plate. It can be secured to your printer with the M4 nut. You can smoosh it into the nut holder for your convenience. Join my discord! https://discord.gg/uYBuFXUmcUAdd this macro into your gcode_macro.cfg file.[gcode_macro WIPE_NOZZLE] gcode: {% set TEMP = params.TEMP | default(200) | float %} M104 S{TEMP} ; heat extruder M109 S{TEMP} ; wait for extruder temp {% if printer.toolhead.homed_axes != "xyz" %} G28 ; home xyz if not already {% endif %} G1 Z10 X-12.0 Y30.0 F6000 ;Start position G0 Z-2 F6000 ;Move to side position G0 Y-19.000 F8000 ; Wipe down G0 Y21.000 F8000 ; Wipe up G0 Y-19.000 F8000 ; Wipe down G0 Y21.000 F8000 ; Wipe up G0 Y-19.000 F8000 ; Wipe down G0 Y100 Z10 F6000 ; Swoosh back to safetyThen just call on this macro in your start g-code or wherever you need it like this:WIPE_NOZZLE TEMP={EXTRUDER_TEMP} ; wipe nozzle macroPlease note it's probably best to put this after your G28 (homing) command so that it doesn't run twice when starting a print.
