-The value for the gcode z offset that fine adjusts layer height to properly shape the filament cross section is not saved in [[printer.cfg]]. The Elegoo ancillary [[Screen]] has workflows that attempt to save it to a file yet this is not a standard Klipper practice and using other printer controls results in indeterministic results. +The value for the gcode z offset that fine adjusts layer height to properly shape the filament cross section is not saved in [[blog:2025-09-07:printer.cfg]].

-The default probe tolerance for its readings using either the [[Klipper]] or [[Elegoo]] defaults allows for inaccuracies of 100 [[microns]], which while often a variation of 30 microns is enough to throw off the filament squish.
