SV08 Z Guide from @esr on sovol discord.

Here's an actually correct way to set your Z offset:

Home the toolhead so the inductive probe will be just above the
plate. (You want the next step to heat it up so your measurements
will include its thermal expansion.),

Heat the bed to the middle of the bed temperature range for the
filament you want to print with. 60C is a good start for PLA if
your filament manufacturer doesn't specify.,

Wait a few minutes for the bed and inductive probe to
heat-soak. Three minutes is about right for 60C, higher
temperatures should go longer.,

Heat the nozzle to 150C and wait 60 seconds or so.  The goal is to
make any goop on the nozzle tip soft enough to be removed by the
nozzle wiper.,

Run PROBE_CALIBRATE to find initial Z.,

Once you complete probe_calibrate, it will prompt you to
SAVE_CONFIG (which can be done with either the button in the top right
of Mainsail or by typing the command into console) Save config will
overwrite the value in printer.cfg and then trigger a firmware
restart.,
+
Note that every time you SAVE_CONFIG you will be making
a change not reflected in your repository, and you will need to
resynchronize!

Print first-layer test as described in the Sovol user manual.,

Live adjust Z as it prints.,

Z-offset is now dialed in.
