Prusa’s first layer calibration in the past would do a long line across the plate to give you time to adjust, I personally just use a piece of paper or feeler gauge (have a tap probe) to set my offset and then run with it. Auto levelling and meshing work extremely well in my experience, if you have something adjustable imo you’re best doing that offline anyhow, the nozzle to surface distance is what matters, you don’t need to push plastic to measure that, in fact I wouldn’t even attempt to do that until I was confident in my measured offsets, tool crashes suck and super close scraped on plastic sucks to remove from a surface.
Are you planning to regularly print large items? Around that price range could get you a formbot v0.2 kit with printed parts. It’s core xy and open source if that matters to you. Print size is 120x120x120 which is small for sure, but in my experience, most of the stuff I print falls in that range (I have a 350mm v2.4 and a mk3s I’ve rarely filled the build plate on either, I’d love a few small printers for quick test prints). It’s also enclosed, can put a Nevermore Micro in it for fumes, and it’s designed to be able to print abs. Supposed to be able to print all the parts for larger vorons on it too if you ever do wish to go larger.
My first printer was a MendelMax 2 kit that I had to sell unfortunately due to a move and not wanting to ship a glass bed cross country. I personally like a kit for a first build, while I get that people don’t vibe with tinkering or maintenance, you’ll learn a lot and you can tweak it to your liking.
You could source from a Canadian vendor (assuming you’re Canadian based on your instance), I’ve sourced a lot from Spool3D in Calgary but will cost you more than the formbot kit. Definitely recommend them for future needs. 3D labtech carries a lot of mods, had great experiences with both of them.
