wow that is awesome, i love it... i already once thought about recreating the one from Bambu - all thought the issue i fear is that it only cleans the nozzle tip and not the whole nozzle body. when i got more time one day i might actually test it, you did a really good job on this one, thank you very much

Thank you. And, true, that might be a problem. However, I'm mainly concerned with the tip as it's used for Z calibration.

If you have a well tuned printer the nozzle doesn't generally get dirty. And for the few times it does it's not hard to clean it manually. I myself still regularly see my printer physically so it's not really an issue. This solution does deal with ooze which is nice when probing with the nozzle.

Nice! The only thing is (for a V2.4) that you can't use is in the middle of a print. You can hit a part while moving back. This should be installed on the gantry.

I have the Decontaminator setup on my LDO V2.4 300, and I rarely use it because it seems to cause as many problems with bits of plastic stuck to the nozzle as it fixes. It was worth adding for the sheet stops alone though. I have not found the screws to be prone to bending, however I printed the parts out of PC carbon fiber, and I turned the screws in as far as they would go and still have the heads catch the sheet, so I don't have screw heads protruding above the level of the sheet. Looks like you used an LDO kit... LDO uses a slightly thicker aluminum bed than the standard Voron spec calls for, so they have a modified version of the Decontaminator parts with the sheet stop mounts raised in height to match. If you are using the original version of the printed parts, then this could be why you have had issues with the screws bending, since they would be protruding out from the parts more, and thus be more prone to bend. IIRC there is a link to the modified parts on LDO's printed parts guide. However there is another issue with the LDO modified parts. They raised the height of the sheet stops, but they don't appear to have raised the height of the brass brush to match. This leads to the brush being essentially level with the bed, so you have to be pretty careful when setting the height and Y position of the nozzle when it wipes (depending on what hot end you are using), to ensure that you don't contact one of the sheet stop screws or even the bed. With the wide nozzles used by the Revo hot end, I had a pretty narrow envelope in which it could wipe; this might not be the case with other hot ends.

Very neat. I love this design. After seeing the Bambu in person the other day I wanted something like this as well. Sadly, I have a bed slinger and have almost no where the nozzle can reach without being over the bed. Got about 10 mm of clearance on the right side of the bed. Was thinking of doing something just like this, then realized that would require some work and had a simpler idea. Since I have bltouch and know my beds z height fairly precisely, I can just use the edge of the bed to do a small wipe right after purging off the side of the bed. The head positions itself off the side, waits for temp, then spits out 10mm of filament, it then does the normal retract length, wipes 5 mm into the bed really quickly, then lifts up and travels to start printing. Surprisingly effective and has the first line going down smooth. Still might try to see if I can recreate this ptfe tube thing in the space i have, there have been an occasion where I found a small blob of filament that did not purge off the head until half way to where the print was to start. would be annoying to have something like that lying around on a larger print. Might have to modify since i cant afford to be yeeting filament towards the bed. That bugger in your video would have hit my x endstop.

i have installed the mod and it worked perfectly untill I printed basically a full bed of prints, and it started colliding with the printhead at the rear while printing, resulting in parts failing due to the bumping, and the ptfe holder breaking. I had to mount the bed further front to even get the printhead over the PTFE in the first place, so of the 350Y Travel i have about 330 left (5mm due to mounting the bed further front, and about 15mm for printhead clearance). I think it is due to my combination of vorons tap (a CNC version of it rather) and the stealthburner. Otherwise this workes like a charm, is easy to print, and the bumpers are a nice and welcome addition!

Interesting. You could upgrade it to have multiple hooks with tubes printed out, just in case one breaks out over time. In other words, make a brush made of rolls. And to be fancy, every single hook would be held on a magnet sandwiched between magnets, and a couple of spare hooks would be clipped on magnets behind the purge bucket.

Needing to cool the nozzel before cleaning adds time to the startup sequence unnecessarily. Better off using some silicon fuel tubing instead of the ptfe tube. Might not be as durable though. I would personally put the effort into finding some silicon sheet and make one of those designs. They work better, are more durable and can be built low profile for 2.4's.

The hotend is cooled to either 150c or room temp first. And in the Bambu lab printers it doesn’t even cool down first during filament changes and swipes across the ptfe tube. The momentary contact with the tube is no where near enough time for it to heat up anything close to temps for it to start breaking down.

I didn't understand how this cleaner helps. Ok you've pushed some filament, cooled the nozzle, removed the filament. But as soon as you you heat it up again some of the filament will go down the nozzle just because of the gravity. And you actually need to clean the nozzle the second before it starts printing, otherwise is dirty again.
