klipper-macros

My Klipper macros, the small Klipper modules they need, and helper scripts, from a Voron 2.4 (350) with an AFC Box Turtle (5 lanes), Blobifier, Beacon, Nitehawk-SB toolboard, bd_pressure, bdwidth and an iHeater chamber heater.

Installs with one script and updates through Moonraker's update manager.

Macros (macros/)

printer.cfg includes only macros/klipper-macros.cfg; that file includes everything below, grouped by topic. Comment out what you do not use there.

File	Macros	Needs
save_variables.cfg	the one [save_variables] for all macros (file bd_pa_variables.cfg in the config folder)	—
blobifier/
blobifier.cfg	BLOBIFIER, BLOBIFIER_CLEAN, BLOBIFIER_PARK, BLOBIFIER_SHAKE_BUCKET, ...: purge bucket and nozzle brush for AFC (Turtleblobifier, heavily modified)	Blobifier hardware, AFC
blobifier_hw.cfg	servo and bucket switch pins	—
print/
print_start_end.cfg	PRINT_WARMUP, PRINT_START, PRINT_END	Beacon, AFC, Blobifier, HEAT_SOAK, iHeater, bd_pressure PA macros (bdwidth is no longer enabled while printing)

filament.cfg	LOAD_FILAMENT, UNLOAD_FILAMENT	—
homing.cfg	HOME	—

Klipper modules (extras/)

File	For
xy_drift.py	AFC_XY_SAFETY_CHECK: measures lost XY steps from the stepper step counts at the endstop triggers (CoreXY). The toolhead position after homing cannot show lost steps.
bdwidth_status.py	exposes bdwidth's motion counter and width to macros (present: False with neutral values when no bdwidth is configured, so the macros also work without it), and keeps a USB dropout of bdwidth (port: usb) from shutting down Klipper: the read is retried every 10 s and the port reopened
bdpressure_check.py	bd_pressure load check (BDP_CHECK_START/STOP/QUERY). Needs the load-check firmware from the bd_pressure load-check-extension branch; on stock firmware it reports "not available" and does nothing.

Scripts (scripts/)

Firmware update scripts for all MCUs (Klipper and Katapult). They contain this printer's CAN UUIDs and serial IDs: see scripts/README.md before using them on another printer.

Tools (tools/)

effective_config.py builds the config Klipper gets from klipper-macros.cfg (includes expanded, duplicate sections merged) and compares it between git refs, for example python tools/effective_config.py HEAD after a change. CLAUDE.md has the notes for working on this repo with Claude Code.

Install

On the Klipper host:

cd ~ && git clone https://mangavalk.com/mangavalk/klipper-macros.git
~/klipper-macros/install.sh

install.sh:

• links extras/*.py into ~/klipper/klippy/extras/ (and hides them from Klipper's update manager),
• links macros/ to ~/printer_data/config/klipper-macros and scripts/ to ~/printer_data/config/klipper-macros-scripts, so the files show up in Mainsail/Fluidd and can be edited there,
• makes the shell scripts executable,
• adds this section to moonraker.conf (once, with a backup):

[update_manager klipper-macros]
type: git_repo
path: ~/klipper-macros
origin: https://mangavalk.com/mangavalk/klipper-macros.git
primary_branch: main
managed_services: klipper
install_script: install.sh

Then:

1. In printer.cfg, after [include mainsail.cfg] and after the AFC includes ([include AFC/*.cfg]):

   [include klipper-macros/klipper-macros.cfg]
   

   bd_pa_spoolman.cfg wraps AFC's SET_SPOOL_ID with rename_existing, which only works when AFC is loaded first; otherwise Klipper stops with Existing command 'SET_SPOOL_ID' not found in gcode_macro rename.
2. Restart the Klipper service (sudo systemctl restart klipper, or Mainsail → services → klipper → restart). A RESTART or FIRMWARE_RESTART does not load new or changed Python modules.
3. Restart Moonraker once, so the update manager shows klipper-macros.

Updates then come through Moonraker; it re-runs install.sh and restarts Klipper.

Adapting to another printer

These are the settings of one printer. Before using a file, check:

• Names: fila_width_0 (bdwidth), bd_pa (bd_pressure), sb_leds, caselight, BedFans, iHeater_H, lane names lane1..lane5.
• Pins and serial IDs: blobifier/blobifier_hw.cfg (PC1, PC3), sensors/motion_sensor.cfg (PC0), heating/chamber_iheater.cfg (serial ID).
• Positions: the bed centre X175 Y175 (350 mm bed) in print/homing.cfg and print/print_start_end.cfg. AFC_XY_SAFETY_CHECK uses the axis limits from your config.
• Settings at the top of a file (variable_...): afc/purge_check.cfg (mode: "enforce", motion_check: False because this printer's bdwidth motion reading is unreliable), pressure_advance/bd_pa_spoolman.cfg (spoolman_url), heating/bed_fans.cfg, heating/filament_drying.cfg.
• xy_drift.py is for CoreXY only.

Comment out files you do not need in klipper-macros.cfg.

Uninstall

~/klipper-macros/install.sh --uninstall

Then remove the include from printer.cfg and the [update_manager klipper-macros] section from moonraker.conf, and restart the Klipper service.
