I just got a free original Ender 3 that I got running and have been having fun with for my first 3d printer. I don’t suppose you have any recommendations on upgrading this thing to get a little more speed out of it??
Say what you will about old hardware, but this one is currently outperforming my Ender 3 that is suffering from thermal runaway, despite a third hot end replacement and PID calibration. Nothing like having a "for parts/not working" tool eating space on your bench.
