I don’t have any experience with this printer, but am similarly curious about it’s viability as a “budget Voron”
Regarding upgradabilty, I saw this video recently with an attempt to turn it into a multi-tool head printer. It’s a work in progress, but I thought it was interesting
Not a big gamer, myself, but it seems like Valve has done a lot of work to make many (most?) Steam games run well under Linux.
Drivers have come a long way, and a lot of things just work, but it can definitely depend on what hardware is in your system.
