Well that's not a dumb question! I was expecting something like: "Did that guy that made Ruby own Ruby Tuesdays?" (can anyone think of something grander?)

So far it's working really well for me with the whole Dave Method and then using the upright extruder with a thread profile. I'm printing at 0.06MM layer height to get accurate threads but it seems to be working, I managed to match an existing thread for a part I'm trying to replicate out of PETG as the existing is crap.

thanks for the interest chris, but the following post answers your question.
