I just received my pre-assembled MK2S.
I tried to install a glass (bought with the printer) on the heatbed plate. First, the glass is 20x20 but the plate is 25x25, it's quite strange, not
Second and worst. Each time I'm trying to print something, the head touches roughly and bends the plate, so I had to reset immediatly the printer and redo a Z calibration without the glass.
Because of that, I tried every menu and finally had to do a full calibration XYZ after a "reset". Not so bad to learn how Prusa works
What I understand is : the MK2S has a special plate, and a sensor on the head to detect position. Nice. But it only works if there is nothing (except PEI sheet) between the sensor and the plate.
So here my questions :
1/can I use a glass over the plate with MK2S ?
2/if yes, how to add 2.97mm to Z to avoid crash with the plate ?
3/how to do calibration tests with the glass ?
4/if it is not possible to do calibrations with the glass, how to disable "9 pts auto-calibration" on every print
