TPU Feed Assist Module with hardened steel?

I have a question about the new TPU Feed Assist Module. Can it also print CF/GF filaments, and is the extruder made of hardened steel?

Does any of you know this?

The only reason TPU need an assist module is because it’s stretchy - meaning the extruder sometimes doesn’t get a consistent feed during the print.

Regular filaments aren’t stretchy, so the extruder is sufficient to pull in filament on their own. They have no need for an assist and don’t benefit from having one.

I doubt the gear would be hardened.
