Works well. It's rigid enough to clean ABS at 180°C.
My print start scrubbing algorithm is:
1. Heat the bed
2. Do QGL
3. Heat the nozzle to 180°C for ABS
4. Scrub
5. Cool the nozzle down to 150°C for Cartographer
6. Scrub again
7. Do Cartographer nozzle-bed toch

Note: I own a 355mm aluminum plate, so I had to move it 3-5mm closer to the front doors to make more space at the back and mount the scrubber properly. (edited)

Using different models but yours macros, thery is one problem:

# ---------- Move to park above bucket ----------
G1 Z{clean_z} F{z_speed}
G1 X{bucket_x} Y{cy} F{travel_speed}

Switch lines, first XY and then Z, because if you run it twice ... the Z can be problem.

# ---------- Move to park above bucket ----------
G1 X{bucket_x} Y{cy} F{travel_speed}
G1 Z{clean_z} F{z_speed}

with that you can also clean nozzle after print without crash ;)

it is there twice, one for move to bucket and second times for clean, also there is need to fill data about brush location twice, use some chatgpt to make nicer macro only with one imputs ... and maybe can be nice to switching sides for brush usage... first left then right side? :) (edited)

Very unfortunate that the Umbilical mod I'm using results in reduced Y travel so that I can just reach the first row of teeth, nowhere near the reference point.

Perhaps something to add to the readme

@Mazvydas_287710 Oh interesting. Do you have any extra Y overtravel in the front of the bed? If so, you can scoot the bed forward a bit.

@jinetix I think I'll try relocate the endstop with this design or similar so I'm not sacrificing bed area https://www.printables.com/model/527499-voron-v24-pg7-umbilical-y-endstop-relocation-with-

Just wanted to let you know that this may be something to at least add to the readme as a warning to check for Y travel.

For the moment I think it'll do a "good enough" of a job to power me through until I redo the endstop. Thank you for adding those variables, I was able to set brush_depth = 2.0 and whilst it doesn't do the best job at cleaning the nozzle - it's good enough for wiping any shmoo for Cartographer nozzle probing.

Also, would ask you to add this to the readme - by default I don't think most will have G2 and G3 support in their configs, at least I didn't.

Just finished installing this on my Voron 2.4 350mm. It works great, thank you!

Something I noticed, with the macro, was the forward movement of 5 was scratching the bed a bit. I reduced that to 3. And also pulled my bed forward a fraction of a mm.

@jinetix

@danielcherubini Oof, definitely do not want my macro to damage beds. Thanks for the feedback. I've rewritten the macro to be more versatile and base its movement off a reference point with some safeties built in. Made a lot of changes, so you should definitely update the macros.

Great design, I love finally having sheet stops.
Remixed in the slicer to suit LDO bed on Whopping Kinematic mounts. That layer shift in the bin is NOT a fault in the original model, I didn't properly align the sections I was "cut and pasting" to increase the height. 28.4mm extrusion to build sheet. Time to learn CAD for easier remixes

As @brasletti noted, the MRW bins don't fit together with the brush holder due to the large inside radius on the holder. I wish I had seen his post before spending hours modifying the height using Orca (I don't know how to CAD). Trying to create a set for LDO plate with Whopping Kinamatic, 28.4mm from extrusion to build surface
