Also got it belted up, but found out afterwards that I used a grease that is controversial on the rails (superlube with syncolor). It's recommended by LDO and Nero3D uses it in his video, but many folks on the Voron Discourse say it's a no-go. I'd rather not risk it, so I'm uninstalling the rails, cleaning/degreasing them, and reapplying some white lithium grease.
I have an i3 MK3S+ with the official enclosure. In my experience it doesn’t really affect PLA unless you’re printing something with zero infill. I had one print that kept curling, and all I had to do was just open the doors.
