I didn’t track it too closely, but maybe around $90. I bought multiples of many of the purchased parts for other projects so I’m really just guestimating.
There are a couple minor errors I ran into in the guides (mostly just wrong screw lengths) but you can start with the extruder assembly for the mini (https://ohai.lulzbot.com/project/mini-104-extruder-assembly/mini-v104/), skip to step 11 if you buy a complete hot-end, you’ll only have to attach the wire for the leveling system, and go up to step 25, then you can move over to the TAZ 6 specific stuff.
First is thermal inserts on the mount: https://ohai.lulzbot.com/project/taz6-printed-part-identification-and-preparation-a/taz-6/
Then final extruder assembly: https://ohai.lulzbot.com/project/taz-6-extruder-assembly/taz-6/
It was a lot of fun printing out and putting this all together, and I learned a lot about how this all works. I ended up not being quite as strict on the wire lengths, at first I was worried my thermistor would read a little off but after doing some napkin math on the increase in resistance with wire length it wasn’t worth worrying about.
Also big shout out to itworks3d for having a lot of this stuff pre-pinned, I’m horrible at crimping so it saved me a lot of frustration.
When I get home I’ll post a few pics of figures I’ve printed with my .3
