The Magnetic heatbed enables you to use flexible, removable steel sheets. There are different properties and strengths of each sheet, but they also have different thickness which affects calibration.
We implemented steel sheet profiles for our printers that need first-layer calibration. The function allows you to create up to eight specialized profiles for your printer setup.
For each sheet, set the Live Z adjust value. Once the values for each sheet are stored on the printer, it is possible to quickly toggle bewteen sheet profiles. The printer will not remind you to change the steel sheet profile, as it cannot sense which steel sheet is installed.
There are currently eight sheet profiles available with predefined, but customizable names.
To set up the individual sheet profiles, please head to the LCD Menu -> Settings -> HW setup -> Steel Sheets:
For each sheet, the following settings are available:
As soon as two or more profiles are configured (by the First Layer Calibration), you will be able to quick-toggle between them directly from the main menu.
After selecting the Rename option in the sheet profile menu, you can change up to 7 characters of the profile name. The word "Sheet" cannot be changed; it is the "Smooth1", "Textur1" etc. that you can customize. There is no way to delete or erase a wrongly selected character, but you can always restart the renaming procedure.
You start from the left and move to the right. By turning the knob, you are changing the characters, and by clicking it, you confirm the current character and move to the next one. When a character position is redefined, a small chevron mark will appear underneath it.
To set up the individual sheet profiles, please head to the LCD Menu -> Settings -> Hardware -> Steel Sheets.
For each sheet, the following settings are available:

Id like to have more. With multiple revo nozzles and multiple sheets i quickly reach 8. And i prefer to have a profile for each nozzle.
I also miss the bed mesh result in Prusa connect like I had with the MK3s+. Since I upgraded to MK3.5s I can see it anymore. 🤷🏻
After saving a new sheet, the printer will start with what you used last. You can see all your saved profiles in the quick toggle. If the sheet profile you were using before is not there, you will need to save it again.
