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.
A heavily customized Ender 5 Pro. I’m running Klipper with an Octoprint server on a Raspberry Pi. I have the BL touch, Micro Swiss direct drive kit, a custom printed heat shrowd and a 20mm fan, silicone spacers, and a spring steel bed. It prints amazingly well and I don’t see myself replacing it any time soon.
