Yeah, it’s definitely a learning experience. A frustrating one, but also a rewarding one.
I’ve had my Ender 2 pro for a couple of weeks now and just managed to get it printing good. The minimum height limitation sensor (don’t know the proper name for it) was not set correctly from the factory. It was too high, and thus my print bed was not able to be leveled correctly until I figured this out.
Also, the slicer software I was using had a setting for “pause at layer height…” which was enabled at about 4 or 5 different times. That was super frustrating too, until I figured it out finally.
Now my prints are looking pretty damn good, and I don’t have to babysit them. I’m pretty happy.
