I don’t think I’d ever seen that .DOC before.
Typing .DOC in the forum search box brought me to:
https://forum.v1e.com/t/learning-doc-pages/15271
the first post of which lists 4 learning .docs.
I know there are other .docs such as ‘milling basics’ but I can’t seem to find a table of contents listing all available .docs. Am I chasing a wild goose or is there one somewhere? I’d just hate to pass over available, helpful information.
