Got my Refurbished ender 3 s1. It's been printing non-stop since I got it a month ago. Easiest printer I've had yet from assembly to perfect print.
Takes 30 min to assemble. The auto leveling was easy to use and worked well.
I had problem with the stock filament because it was entangled, causing the filament to break during printing. When I use the Amazon Basic PLA filament, the problem was solved.
Ive had the ender 3, 3 pro, and 3v2.. This printer blows them away. It was ready to print out of the box. Super super stable. Even my z offset was correct. Mind blown. I did get the creality LED kit add-on and thats having issues but the printer itself is near perfect.
