I’m in the same boat except I do everything for personal use, not shop use. I tend to flood request baskets with my excess ores and gems though instead of setting up a shop as I hate having the onus on myself to supply the goods. I like to be able to just go sell when I feel like it. I have 20 work benches with 12 coils each, 10 compactors, with 12 coils each. 20 refineries with 12 coils each. 20 mixers 12 coils each. 20 extractors 12 coils each.
The way I deal with it is just set an hour every few days to repair them all. It sucks but that’s how ive learned to manage the wear/tear cycle of running a personal, 1 man factory.
The plus side is I dont have to do it. If I’m ever tired of it I just dont do it for a few days. Quit crafting. Everything. I just go and mine for a few days, stock up eve more resources, then repair/farm/craft again.
That’s why I enjoy Boundless. I enjoy doing a little bit of everything, but running a shop makes me feel like have to always be on to maintain things. I absolutely hate that aspect. Which is why I once a week or so will just run around and dump mats in to request baskets that I have bookmarked over the last year.
