I'm considering upgrading my old ender 3 and it looks like the prusa MK4 or bambu labs p1s are the current best options out there.
I like the bambu labs for the fast print speed and x/y print bed. I also love the idea of the AMS - it would be awesome to print in colour! But being closed source puts me off a bit as I currently use octopeint and obico to monitor my ender 3 which, as far as I can tell, Is not possible to use with bambu labs. Also having to upload gcode to the cloud is not ideal.
The prusa however is great because of the open source nature. However the slinger bed and slower prints are putting me off. I have also read that the mmu can be temperamental at best, so printing colour may not be an option?
I think it depends how much you care about the FOSS credentials of Prusa - in terms of printer ease of use, quality, features, I think you'd have to go PS2. AMS by itself is real deal winner, even if you don't do mmu printing.
ile now, it’s clear to me that Prusa sat on its hands for too long. The P1S is fantastic, involves virtually no setup, and gives me out-of-the-box prints better than my MK3S ever gave me even after months of fine tuning. I can’t imagine a world where Bambu doesn’t significantly erode Prusa’s market share.
Came here to second this, I run a print farm of primarily MK3's and MK4's and have recently added a P1S due to my MMU's all dying at the same time (not that they were worth much of a damn before then), the P1S "Just works" and beautifully I might add. I switched over all my multicolor prints to the P1S and have been impressed with better results than with those in the MK3+MMU2S environment. I'm also really starting to like the app and connectivity of the machine. Considering the price of the P1S with the AMS being <= than a MK4 Let alone with the MMU add on, I'd say go for it.
