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 run an ender 3 pro with a sprite extruder, silent board, and gulfcoast robotics bed and gantry. The only one of those that was really necessary was the gulfcoast robotics one cause the 3 point leveling solved a lot of my leveling issues.
Flexible couplers for the z rod was also a great little quality of life upgrade.
