Good to know, thanks! Then that's something I'd definitely love to see explained on the website :) ideally with a clarification how to progress into it at some point. That said, the machine I bought a while ago is a vintage mechanical one, so presumably tough. Also, per @almog's sibling post, I just found https://old.reddit.com/r/myog/wiki/index which may be a good starting point & community for me to explore.
