Taz 4 1.75mm Filament Q

I’m becoming a new owner of a Taz4, and I’m looking to use 1.75mm filaments. I have seen posts that I need to install the adapter into the nozzle, but what I can’t find is what the default nozzle is on the Taz4. It’s unclear to me if it is running a Budaschnozzle 2.0, 1.1, or 1.0 out of the box. I hope someone who knows the Taz4 can help.

The Taz 4 comes with a Buddaschnozzle 2.0c out of the box. The 1.x variants were only found on the older Ao-10x series printers.

The adaptor is basically just a tube with a narrower passage that goes into the hot end. Here is the assembly guide:

The replacement part is basically that white PTFE tube in the center that plugs into the PEEK isolator, but with a 1.75mm hole instead of a 3mm hole.
