Alternative to changing Live Z when I change print sheets?

Hi,

 

So, I've had my MK3S for a few weeks now, and I got both print sheets with my printer. I have worked out that I need to adjust the live z when I change sheets as they are different thicknesses. At the moment, I just have both values recorded, and when I change sheets I adjust the live z.

 

Is this the right approach?

 

Is there anywhere in the firmware to save the two alternative z height adjustments so that I can just choose the right one depending on which sheet I use?

 

Thanks

It's available in the latest firmware release albeit not the final release but it's stable and works fine for me.

Firmware 3.8.0-RC2 for Original Prusa i3 MK3S & MK3

Steel sheet profiles

Magnetic heatbed on MK3S/MK2.5S enables using multiple steel sheets for continuous printing. However, due to a different thickness of various sheets (textured vs smooth PEI), each sheet requires individual First layer calibration. Starting with this release, we are adding a feature, which will store the settings for up to 3 sheets. You can then easily switch between the sheets (profiles) and the printer will load the stored values.

To set up the individual sheet profiles, please head to the Settings -> HW setup. There are currently three sheet profiles available.

-> For each sheet you can do the following:

  • Select - confirms the selection of the sheet, which will then become default
  • First layer calibration - takes you through the first layer calibration process
  • Rename - enables you to change the name, up to seven characters
  • Reset - sets the values back to the factory defaults
  • As soon as two or more profiles are configured, you will be able to quick-toggle between them in the main menu. A detailed description of the behaviour will be released with the final version of the firmware 3.8.0.

Not sure if this is what your trying to do.  You can set a printer profile within slicer. I set a printer profile for each different print sheet i have and just add the Z height difference to the Offset either + or -

I don't know if you have noticed, but the final release of 3.8.0 is now available.
