The printer arrived a week ago and I have learned more from the failures than the successes, mostly because there have been more of them. My bin is now a small museum of plastic spaghetti, warped corners, and a few objects that detached from the bed halfway through and went for a wander.
The first lesson was bed adhesion, which is to say levelling. My early prints curled up at the corners or simply let go and skated around as a tangled mess. The fix was unglamorous: actually level the bed properly with the paper-drag method, slow down the first layer, and stop trusting that "auto" anything had it handled. The moment the first layer goes down evenly, half your problems vanish.
The second was patience. I kept fiddling mid-print, opening the enclosure, nudging things, generally interfering. A print is a twenty-minute to four-hour commitment to leaving it alone, which I am apparently bad at. The same character flaw that breaks my homelab at half seven in the morning.
I did get one clean print eventually: a small bracket I actually needed, dimensionally close enough to fit. Holding a thing that didn't exist an hour earlier is genuinely delightful, spaghetti bin notwithstanding. Onward to the next failure.
