A definitive way to stop the ooze!

I was thinking about using a wire brush, but I decided I didn't want to run my nozzle over a wire brush with each print. Figured it would decrease my hot end life span.  But I think I will have to replace the plastic brush out every so often. While the hot end only comes into contact with it for about a second, I noticed some very slight singing.  While I am sure it will get hundred's of prints of use out of one toothbrush head... eventually I think it will wear out.  Hopefully it will match our tooth brush cycling.

Yeah I used super glue to attach the metal piece.   Ditched that code which I need to update the other post.  It was working, but then every once I and while it would fail, which needless to say made it unreliable.

I'll post the code I used for this one in a little bit.

Yeah the oozing thing has driven me nuts since day one.

its a great idea i just wish it didnt look so ghetto!

So here is the start Gcode I put with it.  Just change the coordinates to match the target brush area.

I used cheap super glue from the local hardware store.  None of that fancy gel stuff.  Back in my industrial design program I'd go through so much of it to build models etc... The glue of the gods I tell you.  Not to mention great to have on the tool bunch when you slice yourself open on accident.  That's how my Dr friend takes care of all his kids cuts that aren't deep enough for stitches.

Anyhow the Aluminum on aluminum bonds great enough for this application.  Acrylic can be a pain to super glue to.  I'll let you know if it falls off. I've ran 4-5 prints so far no problem.

@Molecular Concept: Whaaat zip ties, and old used 6 year old sons' tooth brushes looks ghetto? j/k.  You could always use a new tooth brush, and instead of zip ties, screws through the back to hold it onto the platform, then you could have just the brush part with no stem.  But that is also a bigger pain to change out.  Zip ties are just so cheap, and old tooth brushes were convenient.

Mod done! I used top part of an opened can, and a brand new Tesco everyday value toothbrush for a whopping 49 cents for two toothbrushes

Should appear less ghetto style and also replacement is quite easily done.

I tried to glue it in the same position Pastprimitve did but had to modify the code a little bit
