- HOME always homes Z with Beacon contact and recalibrates, also when the
printer is already homed (home_method_when_homed = proximity used the
model of an earlier print without touching the bed). PRINT_START homes
Z again after QGL, before the brush takes the nozzle below Z0.
- _Z_CHECK: after the soak, compare Klipper's Z with a BEACON_QUERY
reading at Z3 over the bed centre and stop the print above 1 mm.
Warns and continues when BEACON_QUERY leaves no new
printer.beacon.last_sample.
- Nozzle guard (extras/bdp_guard.py, print/nozzle_guard.cfg): reads the
bd_pressure force over I2C every 20 ms while armed and, in stop mode,
shuts Klipper down on a touch. Armed for HOME X/Y, QGL, Z homing, brush,
mesh and the Z check; starts in log mode to collect peaks per phase.
- Chamber prints: load and purge the first tool before the chamber heats
(_LOAD_FOR_CHAMBER replaces _UNLOAD_FOR_CHAMBER). A cut unload leaves a
piece of PLA in the extruder that softened in the hot chamber and jammed
the ASA load.

bdpressure.py leaves the extruder at the last PA_CALIBRATE test value
(0.098) when it finds no result, and _PA_AFTER_CALIBRATE saved that as
the calibrated PA (lane1 after an AFC pause, lane5 after the sensor went
silent). A run is now rejected, with nothing cached or written to
Spoolman, when the PA is still at the end of the scan, the printer
paused during the test, or bd_pressure gave too few or too few different
readings. The previous valid PA (or fallback_pa) is applied instead.
bdpressure_check reports pa_points and pa_distinct from the bdpressure
module's last PA_CALIBRATE data for this.

bdwidth's motion reading stays at 0, its per-reading width compensation
made the flow jump between 77 and 119%, and a USB dropout shut down
Klipper. PRINT_START no longer enables it. _PRINT_CLEANUP,
BLOBIFIER_CHECKED and PURGE_UNTIL_EMPTY only send bdwidth commands when
[bdwidth fila_width_0] exists, and bdwidth_status reports present: False
with neutral values when it is not configured, so the section can be
removed from printer.cfg.

bdwidth reads its CH340 from a reactor timer without error handling, so
"write failed: [Errno 5] Input/output error" shut down Klipper mid print.
bdwidth_status now wraps the sensor's Read_bdwidth (bdwidth.py itself
unchanged): on a USB error it closes the port, reports once and returns
False, so bdwidth retries every 10 s; the port is reopened when the
device is back. New status fields usb_ok and usb_errors.

Macros as they run on the printer (Voron 2.4 + AFC Box Turtle +
Blobifier + Beacon + bd_pressure + bdwidth + iHeater), the Klipper
modules they need (xy_drift, bdwidth_status, bdpressure_check), MCU
firmware update scripts, install.sh with Moonraker update manager
support, and READMEs.
