waste / nozzle priming bucket - material for lip?
-
@vwegert I cut that sock to free whole nozzle as it got ripped after 3-4 prints ...
-
I have a Cubex Duo that came with a waste bucket. It had a spring loaded teflon strip that the nozzle would scrape against to knock the drool off the extruder. The teflon strip worked fine even at ABS print temperatures because it was only in contact with the nozzle for a fraction of a second as the nozzle passed over it.

@mrehorstdmd good idea!
-
I have seen some printers use soda cans that were cut into strips as a wipe area.
-
@chanders Hmmmm... Makes me want to check whether I could fit the lower half of a soda can into my printer...

@vwegert This is exactly what I do. I use a strip of silicon rubber which is pressed into a slot in a long "bucket". My purge commands consist of extruding some filament then wiping the nozzle back and forth across this strip. I'm 10,000 miles away from home at the moment and only have my phone with me so it's not easy to post a link. However, take a look at my blog which is linked in my signature. There is a detailed post describing how I print with a purge bucket. HTH

@deckingman This looks like what I had in mind originally. Do you happen to remember what kind of silicone strip you used?
-
@vwegert Not off hand. I think I just did a "Google search" for silicon rubber strip or some such term.
-
@deckingman You could probably get a silicone strip from a squeegee...
-
I used a bit of silicone sock from e3d. It worked nice...
Silicon and heat resistance... -

Yes that would have worked too. I found some strip about 20mm X 3mm but IIRC had to buy a I metre length.
-
I found that the wire bush destroyed a brass nozzle pretty quickly. I ended up using a silicone strip as others have mentioned. I get the silicon from McMaster-Carr and then cut it to size.
-
There's a lot of small, cheap, kitchen junk that's made of silicone.
-
@mrehorstdmd I've actually ordered one of these cheap-o baking mats made of heat-resistant silicone - cheap enough to try and cut it to strips...
-
@vwegert I kind or forgot but I actually made a video of my purge bucket in action. If it's any use, check it out here https://www.youtube.com/watch?v=zNNmZCXErYY&lc=z234cfh4dkylhh4ra04t1aokgl1ownrihxxz0fiwil5xrk0h00410
