I put off getting a 3D printer for a very long time, hoping things would settle out and they would "just work out of the box" like most tech things do. I finally pulled the pin and got this one. It is amazing! I can't believe all the things I can make with this. I am a do-it-myself or it doesn't get done and am constantly tinkering with fixing something. I have built many items that I would normally have had to make out of wood or metal by hand and the precision of the prints is so great, that I rarely have to redo anything. A little sanding is usually all it takes to finish off even the most demanding items since I can start so close to what I want.The setup is very simple, since they have it almost all assembled in the box. After putting the few items together, just double-check all the adjustments and you are off and running. I didn't have any problems with any of the adjustments on mine, but others have reported issues with loose tolerances.The bed leveling is very much worth the extra time to get correct. I watched many videos and read a lot before I dove into this and still took a bit to get things reliable on my end. I kept changing things and adjusting to see what difference the changes would make until I am pretty comfortable jumping into a new print with only a few seconds of setup. The CR auto bed leveling system seems to help but don't forget to adjust the Z-level to get the extruder just right on the bed. I am finding that the correct settings here really cut down on other problems that may not even seem to be connected to a non-level bed.The filament-out sensor is vey useful also, not only when a spool actually runs out, but I have used it to pause prints to change colors and it works very well. I have printed a camera mount to run on my Octoprint box to monitor long prints and a tool holder since the drawer is a little difficult to get in and out of with the printer in an enclosure.The enclosure has also helped a lot since the environment can be much more consistent with temps and humidity with everything insulated. It also keeps dust off the machine since we run a wood stove and live in a dusty area.I am very happy with my purchase, and am telling everyone that the time has come to jump on this technology - things have matured to the point of being pretty turn-key at this point. I know the Ender 3 is an entry-level machine, but the S1 Pro has the options I would have eventually bought to make it a decent machine.
