I also currently own a single tool XL. I ordered it a long time ago as a kit, but it became clear if I wanted it any time soon (this was last summer), I needed to switch to a “fully assembled” version for $500 more.
Well, not fully assembled. I had some work to do to get it set up. The large container of giant gummy bears was all over the place inside, and it took all my attention to unpack and remove them. I did not pay attention to other things, such as -did anything else break loose?
Leter, I discovered the bed was not as flat as I assumed it would be. It was lower on one side. Could this be from shipping damage? I went around and around with Prusa on this, and it took 4 months or more to get anywhere. Depending on how you were using the printer, it was a non-problem or a big problem. In my case, it added to slight warping, and when printing parts that were attached in opposing directions, and thus multiplying the error times two, it was a no-go.
The printer does print well most of the time, and certainly is large. I bought a Creality K1 MAX to tide me over, and it seems to work well, and faster. There is another whole story there.
I finally got agreement to refund my $. Because the alternative was to receive a new bed, take the printer apart, remove the original bed, install the new bed, and reassemble the printer. Based on the time it took to “merely” install the head and connections when receiving the “factory assembled” version (that is to say, finishing the assembly), I figured at least a day or more of time I don’t have to spend, so $ to pay someone to do it.
So, I opted for the refund rather than warranty repair. I had a high regard for Prusa, this has tainted the waters somewhat for me. I have an MK3S+ down for calibration as well. Something is wrong with it and I have not figured out what it is. Prior to that, it was flawless and reliable.
I think the Chinese are pushing the envelope faster than Prusa is at this point, and I think they are going to have trouble keeping up. Well, time will tell.
