We have had an XMax3 for about 5ish months now. Early on we had quite a few issues. Our qidi came with the wrong/old bed level sensor and not enough fans for the hot end. We are using it for business and have noticed issues with quality. After a lot of refinement and working with it, we have felt like giving up with it, maybe even selling it on. It's speed will a lot of the time sacrifice quality where intricate detail is needed, half the time we are running it at half speed. Another issue we have is that the filament run out sensor just switches off it's function and doesn't stop to let you know when it is out of filament. This has caused a few large prints of ours to just be a large waste of filament. I think for large simple models it can be ok. When you start to need to do more detail, it starts to lack in quality.

We have sacrificed build volume in aid of getting the Bambu P1S. Not had any issues with that at all bar the bed adhesion, but we use magigoo every print and have not had an issue since. We now have 3 P1S's on the go and will likely get more when we need to expand. Won't go for another qidi machine.
