"There is no huge open source for regular printers..."
Given the state of regular printers, I'd say this is an excellent argument that there should be! I prefer actually printing to tinkering as well, but I've been around long enough to watch corporate interests destroy any number of tech related things from 2d printers to search engines. Bambu and Apple are both excellent examples of what not to do as well.
I installed the X-plus firmware, switched to LAN mode, blocked WAN acess at my router and use Orca slicer and honestly, I'm pretty happy with the result. That doesn't mean I'd give Bambu a second chance after their recent moves.
