Stock G28 homes X first and can sweep the dock. Homing.cfg was documented but missing. Z home refuses to trust active_tool. Closes BondtechAB#8
The override behaviour is unchanged. Comments and the README sequence now say what happens, not the Jinja mechanics.

The README has pointed at
homing.cfgfor a while (Y before X, then Z with a nozzle on the cell) but the file was never in the repo, so stockG28still homes X first and can sweep the dock. This adds it. Closes #8.Z homing does not trust the saved tool number. That value can be wrong both ways: empty while a tool is still in the head, or seated after a partial release (the "retract before 3mm+ extrusion" case). Before any T0 pickup or probe, the load cell has to show a seated tool (
home_min_force_ginindx.cfg, default 800). No cell, or an uncalibrated cell, is an error. A loaded cell with no known tool is also an error.G28 Zhomes with the seated tool, not always T0, as there is no reason for that restriction.
