Forgot to mention: The Taz 6 uses electrical contact (not limit switches) between the bed and the nozzle to find the bed height, hence the need to clean the outside of the nozzle.

That is the official recommendation Lulzbot support gives. Brass nozzles are wearables, just replace it. I use an anchor in my start gcode to clean the nozzle before a print but that won't help as much with the Taz 6 and it's bad leveling system. I'd recommend adding a probe to use mesh bed leveling if you're comfortable modding the printer.

Short of these solutions try to keep it clean with the tweezers that come with the printer and brush as little as possible. You could also switch to a hardened nozzle.

Interesting, I didn't know that was considered a wearable part. I don't mind doing some mods, as I'll probably rebuild that toolhead as soon as the new one arrives and I can print again (everything except the heater block and printed parts looks salvageable).

Is there any particular probe you'd recommend?

I prefer the BLTouch and even did a write on installing it in the Taz 5 over on the forums.

Nice. I'd be interested in reading that if you don't mind linking it here.

There are a few steps I never finished fleshing out and the wiring image I was uploaded disappeared, don't know why, and I don't have a back up. So if you end up with any questions let me know and I'll answer the best I can
