Domeing of flat surfaces over infill cells

I remember the knobs under the heated bed are quite tight; they’re usually only used when you need to perform bed leveling. But the bed is usually leveled one time at the factory before shipping.But I don’t think this is what’s causing your issue. Still, I’ll add the steps just in case. After the bed is mechanically leveled, you normally only need the software-level compensation from now on (see image) and won’t touch the mechanical knobs again. [image] before mechanically leveled start ，yo…

I think you need to do a mechanical bed-leveling first to make sure the physical platform tilt is minimal. Most auto-leveling systems then use software to compensate for the remaining small height differences on top of that. If after physical leveling and printing with auto-leveling checked it still looks like this, use these test photos and contact support to request a new heated bed.
