I would like to give you a review on how the Ender 3 S1 Pro works, but I can't do that. Why? Because the manual is so poorly written that I can't even understand the bed levelling (which I do understand in concept) instructions. They are vague. They tell you to do it one way and then do it the other way. There are steps missing. So, I don't know if it's a good printer because all my models slide off and its due to bed levelling that I get can't set properly. I bought it a year ago and gave up trying to get it to level. I just tried again (1 year later) and remember why I had so much trouble. The manual is useless.
