@Tomek: I'm just worried about the brass causing more wear than I want on my nozzle flat surface at the tip.  Maybe that is a non-issue.  If you do it that way, let me know how it works out.  I'm probably being over cautious.  Although I only had one parking accident, and it was my bad, under manual control when I was installing it, and not thinking, and the brush was still fine.  It singes a tiny bit, but is really effective.  The plus compared to the wire method I have seen that is similair is that the brush seems to do a better job of dealing with the messier oozing issues where it doubles back on itself, and you have a bunch of loops hanging off the nozzle.

@Tomek.  I've had no luck getting my anchors to stick to the bed consistently.  I've got the Glass and hairspray thing going on.  Besides those issues I really like how convenient it is to pull off filament without touching the hot end, or having to grab a tool.

Also I'm gearing up to use it as a production tool, creating an auto eject system, etc... I just want it to work 100% of the time with no thought.  Plus it keeps cavities from forming on my hotend;)

Hey, I agree, there are benefits to this nozzle. At least you recover the part of your print platform where you normally stick an anchor.

I just don't like too much the idea of using a brush with meltable tips, in case of accidental parking the nozzle there - how about a soft brass brush?  I guess it ups it to a $3 mod instead of a 50 cent mod. 

If you ever have problems with hairspray and glass method, make sure to try the acetone glue treatment.  It is too strong of a grip for me usually, and I only use it now when I have a tiny base for a big object.

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

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.

This is similar to what another member does-  he/she puts down 7mm in the start as an "anchor" and then leaves that location, leaving behind the blob.

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.

Thanks!
Nick

I tried using the edge of the bed to clip the ooze off, and it worked 50% of the time.  This so far has worked every time. For the cost of your son's old tuth brush, a flat piece of something, two zip ties,  and 20 minutes of time, you too can be the lucky owner of this mod;)
