Z-A Coupling

The auxiliary tool hangs below the Z spindle. Beyond a small Z descent the two collide unless A drops with Z. The rule in machine coordinates is A − Z ≤ (A_home − Z_home) + clearance. When enabled, the planner refuses moves that would violate it and the gcode preprocessor injects pre-position A moves into uploaded files.

Changes are written to aux.json when you click the master Save button at the bottom of the settings rail. Homing rates and the limit polarity are pushed to the ESP immediately; any running motion is unaffected. Re-home the auxiliary axis after changing direction, sign, or step settings.
