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.
Sidewinder X2 that I’ve modified quite a bit.
I’m using a genuine BL Touch, aluminum bed with magnetic build plates, removed filament spool from the top of the printer, Klipper/MainsailOS, Pi camera, silicon bed spacers, bi-metal heat break, larger part cooling fan and duct, and more.
I have probably 600-800 hours on it so far (about 500 since installing Klipper and about a year of use before that), but it’s working well so far with all the upgrades.
