I mostly loved my K1 Max but could not get the x-axis dialed in properly, so any time I tried to print anything with a circle it would come out a bit lumpy. I’d sold my CR-10 and upgraded because I was tired of the constant tinkering and just wanted a tool that, while it will need maintenance and the like, would mostly just do what I wanted. Also my BIL got a P1S and I was hugely envious of the AMS system haha.
Luckily a buddy was looking to upgrade as well and is buying my K1M off me so I ordered a P1S and just got it set up today and…it’s just working and I’m so happy. Benchys between the two look about the same, although the textured build plate gives a nice bottom layer, but I printed a couple trinkets my wife likes to hand out at Disneyland and it’s just night and day better quality.
I’m sure I got a bit unlucky with the K1M and lucky with the P1S but it was amazing just printing stuff and it came out fine the first time.
There is custom firmware for the bambu printers but bambu won’t support you if you install it. They won’t try to stop you from doing it either.
Not for now, thanks to some YouTubers getting them to reverse course slightly on some of their printers (to be fair, Creality took similar pressure). However, I have less trust in BambuLab at this time. That said, I’m not about to even try to claim that they’re bad printers. Plenty of data out there to say otherwise and their AMS is pretty slick.
And creality won’t support you if you buy their printer anyway!
