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.
You're going to want to install klicky, or some other probe, out of the gate. It's used for quad gantry leveling (mandatory IMO) as well as bed mesh (I've personal not done this yet). I printed the fixed mount, but it's out of plane with the hot end mount so I'm working on printing the adjustable mount.
Good to know. I got the Klicky parts through PIF, so I'll add it to the list!
