Currently using a FLSUN Super racer. It’s a delta style printer and fast as hell compared to the printers I had before. 400 hours on it currently.
Had a Ender 3 before it. Lots of issues. Ended up giving it away to a friend who still uses it and still has random issues.
First printer was a Printrbot Simple Metal. Bought one the moment a heated bed was a option. Great printer for the time, but dated now. Keep thinking about resurrecting it to print flexibles on of these days.
I use a Prusa MK3 (not MK3S/+) that I got in 2018. Later this year I hope to get an MK4 to join it, and maybe a Voron 2.4 for big prints. My first printer was a SeeMeCNC Rostock MAX from 2013. Its controller board died for the second time just before I got the MK3, and I never fixed it.
