Building a Voron is on my list of things to absolutely do this year. I got into 3d printing at the start of last year with an Ender 3 clone, and by the end of the year I had ended up building a Mercury One.1 printer and recently an ERCF. It's a ton of experimentation and calibration to do, but it's so satisfying to build this kind of machine, being someone who has always enjoyed making stuff, but has mostly focused on making software.
