You can order a new surface on snapmaker support. Or you can pre Order the Quick Swap Kit since there is also a new frame. You can use the “warped one” for laser / CNC.
And yes, for sure warped beds should not delivered in a 1500€ machine. When mine would be really bad (but it isn’t, i can print pretty well all over the bed), then I would run a measurement for surface like here: On achieving a perfect level
And when it is really out of specs, then support should arrange some new frame for free.
But now i am really out in this topic
