We used our brand new SnapMaker2 A350 for some tests and it was pretty good for results.
I wanted to test a sligtly bigger object en we had a serious fail in the printbed!
Upon inspection we saw that the heating bed was seriously bended, see photos.
I think the aluminum has expanded during the heatup and moves the printboard outward.
I am very shocked by this and do not really know what to do about this.
The print was a base of 100mm circle 3 mm thick
