# Nozzle collision guard: bd_pressure watches the nozzle force during moves
# that must not touch anything (needs extras/bdp_guard.py and the bd_pressure
# load-check firmware). See extras/bdp_guard.py.
#
# mode: stop shuts Klipper down on a touch; log only measures and reports
# each phase (console and klippy.log, "bdp_guard:"). A phase can override it
# with _GUARD_ON MODE=log (the brush does).
# Measured 2026-10-18: peaks 1-8 in all phases except the brush (47); a
# light finger push on the cold nozzle gives 41.

# M400 first: BDP_GUARD_ARM/DISARM act at once, not in the move queue, so
# without it the guard would watch moves that are still queued (contact
# homing, extrusion) or stop watching before the armed moves ran.
