Hello All,
I have an X1C for about a year now and it seems the wiper is hardly working at all. Any aftermarket parts or fixes for this. I had another printer that had a piece of brass wire brush where the nozzle would wipe over and it always worked. Curious if anyone has made something to hold a wire brush to be used as a wiper.
Open to any help or suggestions.
Yea I agree, the roller only contacts and removes filament from the nozzle tip, not the upper portion.
A brass brush and back and forth motion would probably be an improvement….maybe one day.
Yes I agree with you. Particularly when restart after pause or the end of the first layer inspection. This is the reason I disabled the first layer inspection in the printer options
On other printers (JGMaker ArtistD) with a brass brush I found that it fairly quickly got clogged up with melted plastic, so I replaced it with a flat square of ptfe flapping up - so that the nozzle wipes itself on the edge of the square (as per the Weedo X40).
I guess the round springed ptfe on the BL is better than this because it does also wipe the left and right of the nozzle a little bit too.
I wonder whether a second wiper made out of flat PTFE with a V cut out to match the angles of the nozzle would wipe the front and back of the nozzle a bit too.
I have heard kapton tape wrapped around the ptfe tube does a better job than the smooth ptfe tube but have yet to try since I typically just wipe off the tip every couple prints. Would be a quick trial mod if you have some laying around.
There are a few options on Printables which I intend to try soon (but have not got around to yet…) including adding a brush and using rectangular section PTFE. Search there for “bambu wiper” and they will pop up.
Only had my X1C a couple of weeks and the wiper seems counter-productive when using PETG or ASA - it just smears the goop over the nozzle, ready to be dropped on to the print seconds later…
The X1C wiper (mine, at least) was never very reliable, especially with PETG.
After the print started, there was not much to do; in the past, I used to pause and manually clean it, but it was not a reasonable solution.
Recently, I noticed improvements, which can only be with dry and calibrated filament, clean nozzle before or after print if necessary, and clean wiper occasionally.
Besides this, the other changes were firmware and the ageing of the wiper.
FWIW: the wiper is a consumable and Bambu has replacements on their site: Nozzle Wiper | Bambu Lab Global
With that said, yeah it doesn’t always do the best and I sometimes clean the nozzle manually between prints as well.
Here is the wiper with a silicon sheet:

I think it works better than the stock one.
