This is WristWatch, a standalone extruder designed by @bythorsthunder WWG2 is built as an alternative to WristWatch BMG etruder - but it uses Galileo 2 insides for pushing filament. Development started approximately when G2SA was being worked on, but later Thor was kind enough to allow me help him with further refinements of this extruder.
My exact issue as well, I was hoping swapping from G2se to this version would alleviate this issue, yet it seems worse now. Looks like it may be the smooth roller as it doesn's have a way to bite the tpu to feed it.
