I just contacted Qidi Tech to see if they were interested in donating a Qidi Tech X-Max 3 printer. I am about to do some 3D printer reviews on this page that will include the Anycubic Kobra Max, Anycubic Kobra Neo, Flsun SR 3D printers. I think this Qidi Tech 3D printer is going to be a great addition to this review. I wil keep you posted on their decision.

UPDATE 6/4/2023
Haven't gotten an answer back from QIDI.
I received my Flsun SR and compared with the Anycubic Kobra Max in speed, the Delta blows it away. Very happy with the performance and out of the box experience. The Kobra Max prints very large items compared to the Flsun SR. Using each one for something different. I am about to receive a Anycubic Neo. Let's see the performance of that one. I can print three things at a time and that way I don't have to wait so long. Did a Namor Submariner on 350% scale on the Kobra Max, huge print. Doing a Tenjin also at 350%, super huge print and many days of printing. Will post pics when I paint them with airbrush. Planning on using resin as a primer and then spray paint primer and then paint. Bought a cheap bottle airbrush for the resin. That's another experiment!!

I would say that the Anycubic Kobra Max is by far the best reliable 3D printer of the three that I have. No failed prints, great bed adhesion and good prints and LARGE format. The Flsun SR, well being fast is great but I am having a lot of problems with bed adhesion. The first prints were great but then I am starting to have problems with the adhesion and the final bed leveling is also a problem. The Anycubic Neo is super slow BUT it produces some great prints right out of the box. Had a problem once with adhesion but I was able to get it back to work okay.
