async FlexHead1.move_to_safe_z() → None#

Raise the tip or nozzle to traversal height; never lower or move laterally.

Uses the deck’s computed traversal height and the robot’s current tip/nozzle position. No mounted tip is required. Automatic calls after tip and liquid operations happen after bookkeeping commits, so a failed retraction does not undo a successful pickup, drop, or liquid transfer.
