Prusa XL series: Front Nozzle scrubber (including G-code)

sI heard that people would like to have a nozzle scrubber system on the front, that they can use with g-code. While my other nozzle scruber are great for multitool printing, this one is intended to be use before calibration. When heating up, the nozzle Ozzes a bit. With the correct G-code the nozzle can be cleaned with this front mount.

BUT WHY YOU ASK? 

Well if the nozzle is not clean BEFORE it probes the surface, the first layer will not “be perfect” . My other nozzle scrubbers only clean the nozzle between tool changes, but not directly before the surface scan. 

What do i still want to implement? 
1. Screws to hold the brushes (dont like them to wiggle around) Done 16.11.2023
2. Bucket around the brushes

UPDATE 15.11.2023: Added a retraction line in the G-Code to compensate for oozing.If you want to delete it dont add the line “G1 E-10 F2400 ; more retraction to compensate oozing before nozzle cleanup”

Now to the fun part ;-)

Ive ordered these brushes:
https://www.amazon.de/gp/product/B086JP3C45?ref=ppx_pt2_dt_b_prod_image
 Please have in mind that wider Brushes will probably need adaptation of the mount(spacers)

And you will need these Screws:
2x M4x25mm (28mm max) for the front.
2x M4 Nuts
4x M3x20mm for the Heatbed Plate mount
3x M3x 10mm dependent of your nozzle brush

Also 3x m4 nuts and 3x m4x10mm screw to lock the brushes
