Hi,I have the Bed Mesh enabled and have done a hot calibration.Does the bed mesh data get saved into Klipper?If I power down the printer is the calibration lost?How often do I need to run it?Will the calibration compensate for .66mm?Thanks.
The data is saved to the end of the printer.cfg file with the name you gave when starting the bed mesh calibration.
The calibration will not be lost. However, the latest version of Klipper is not automatically loading the 'default' bed mesh anymore. You would need to load it before starting a print or add a macro in your printer.cfg to load it automatically.
I only run it once for a defined temperature or when I remove the flexible print plate.
Yes, it should compensate for it, IF the observed curvature is effectively due to the bed and not the linear rails. Another limitation would be if you have a very sudden change in the z height on the bed, like a deep scratch.
