Definitely a valid thing to have. Imo, as long as it provides value to you creatively or intellectually, then it’s a worthwhile hobby. It sounds like you are using it as well, so that’s just a bonus really.
I’m halfway into that mindset, but got myself a bambu after fighting an Ender 3 for so long and for now at least I’m content to just have a working printer instead of a half assembled one 80% of the time. So many calibration cubes.
Well this is… disappointing. I picked up an A1 at the end of last year because it “just works”, and I was tired of fighting my Ender 3 instead of actually printing with it. I’m extraordinarily happy with the quality of the printer itself, but I’ll be refraining from updating the firmware I guess, as I don’t allow it to use cloud services, and it lives on my LAN as the only means of management.
