- 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.

With the chamber heated, a filament left in the toolhead path softens in
the PTFE tube (PLA loaded, ASA print). After the first HOME, PRINT_WARMUP
unloads the loaded lane when it is not mapped to the print's first tool
(PRINT_START would swap it anyway). A failed unload stops the print
before the chamber heats.

PRINT_WARMUP: bed heats during the warmup, the nozzle only waits while it
is above 170C (Beacon contact limit 180C), one HOME to get over the bed,
then M190 and HEAT_SOAK. No more filament load and 220->150C cycle there.
PRINT_START (on the soaked bed): one QGL, one contact Z calibration, mesh,
heat over the bucket, load the initial tool, PA for all lanes, load the
initial tool again if a calibration changed lanes, G28 X Y reference.
Loading after the contact keeps ooze off the nozzle for the calibration.
PA: calibrate each lane at its own filament temperature (was the
temperature from before CHANGE_TOOL), and apply the loaded lane's PA
after PA_CALIBRATE_ALL_LANES (the last cached lane's PA won before).

The motion timeout switched the nozzle LEDs off during prints, motion
switched them off when idle or paused, the timeout counted from the first
movement, and every _status_* macro stopped the nozzle light.
- _LIGHTS sets case light and nozzle LEDs from presence, print state and
CASELIGHT MODE=AUTO|ON|OFF; the timeout (60 s) starts at the sensor
release
- _STATUS STATE=... replaces the _status_* macros; logo effects only
cover the logo LEDs and use REPLACE=1
- heater gauge while heating, print progress, paused, error flash from
_ERROR, part ready once the bed is cool, dim night mode when idle and
nobody near, cleaning during BLOBIFIER_CLEAN
- removed unused effects and macros, 12 fps for the toolhead effects

action_raise_error aborts while the macro renders, so an M117 in the same
macro never ran and errors such as the RESUME lane check only reached the
console. messages.cfg adds _ERROR (M117, then raise in a separate macro)
and _WARN (RESPOND TYPE=error + M117); all errors and warnings use them.
PAUSE shows AFC's error as the pause reason; RESUME, CANCEL_PRINT and
PRINT_WARMUP clear the display.

PAUSE stores the lane the print needs (AFC's next_lane during a failed
tool change, otherwise the loaded lane). RESUME stops with an error when
another lane or none is loaded; RESUME LANE_CHECK=0 skips the check.
AFC_CLEAR_ALL_MESSAGES clears AFC's whole message queue
(AFC_CLEAR_MESSAGE only removes the first message).

A bd_pressure that does not answer used to be reported as "pressure
skipped" and the purge passed unchecked. It now fails the check, so in
enforce mode the printer pauses (and a resume purge stays paused).
PURGE_CHECK_IGNORE_SENSOR lets purges pass without the sensor until the
print ends; _PRINT_CLEANUP clears it so the next print checks again.

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.

_RESUME_PRINT purges 40 mm with BLOBIFIER_CHECKED (instead of the 2 mm
unretract), so the nozzle is primed, wiped and checked before going back
to the print. A failed purge check raises an error that aborts the whole
resume, AFC_RESUME's restore included, so the printer stays paused; the
next RESUME checks again. RESUME PURGE=0 skips the purge.
The purge check records a failure in _PURGE_CHECK_CFG.last_failed, since
its PAUSE has no effect while the printer is already paused.

The CCD motion reading stays at 0 (actual_total_move:0), so motion mode
only produced false "Rounout" messages. ENABLE_WIDTH keeps the flow
compensation and the runout on a missing width; clogs and breaks are
left to AFC's buffer fault detection (filament_error_sensitivity).

Klipper's G10 retracts only once until a G11, and nothing sends G11 on
this printer: the G10 in PRINT_WARMUP used up the retract, so PRINT_END
never retracted and the nozzle leaked while cooling down.
- _NOZZLE_RETRACT retracts and remembers the amount in the saved
variable nozzle_retract (survives restarts, capped at 15 mm).
PRINT_END retracts 5 mm, PRINT_WARMUP 2 mm, CANCEL_PRINT 5 mm plus the
park/PAUSE retract.
- _NOZZLE_UNRETRACT in PRINT_START pushes it back over the bucket before
the wipe.

- RESUME is defined only in print/pause_resume.cfg; heat_soak.cfg's
duplicate replaced it (no unretract, no fan restore). It now runs
HEAT_SOAK_RESUME -> _RESUME_PRINT -> RESUME_BASE.
- PAUSE runs PAUSE_BASE first, then retracts and parks once (X20 Y345);
a parked flag makes resume undo only what PAUSE did.
- New _PRINT_CLEANUP shared by PRINT_END and CANCEL_PRINT: heaters incl.
iHEATER_OFF, fan, M221 S100, bdwidth off, mesh and skew cleared.
In PRINT_END it runs after RESTORE_GCODE_STATE so the flow reset sticks.
- Add CLAUDE.md and tools/effective_config.py.

- Split the macro files into folders by topic (print, heating, afc,
pressure_advance, spoolman, leds, sensors); klipper-macros.cfg is the
one file printer.cfg includes. Macros moved unchanged; the effective
config is identical apart from the paths of the PA shell scripts.
- Add the modified Blobifier (Turtleblobifier for AFC) and define
[save_variables] once in save_variables.cfg instead of in both
blobifier.cfg and the PA macros (same file, bd_pa_variables.cfg).
- PRINT_WARMUP: heat to the loaded lane's temperature before the first
tool change. AFC skips heating when the loaded lane's tool number is
not in the print file's temperature list, and the unload then failed
below min_extrude_temp.
