Brings in:
- W axis (auxcnc) integration via ESP32 over /dev/ttyUSB0, including
the W axis settings panel, DRO row, jog row aligned with X/Y/Z, and
collapsed home-only W controls.
- README + W axis docs covering macOS build/flash and the new UI.
- Build & flash docs for the Pi firmware (BUILD.md), including the
cached gplan.so build via Docker (~30 min first time, 3 sec after).
- Hooks v2: external triggers during G-code execution that block
unpause until the hook completes.
- V09 full UX redesign mock + implementation plan + mock variations.
- V09 implementation: new app shell with underline-ribbon tabs,
Program / Console / Settings shells, V09 jog/macro palette, slim
status pill replacing the old chip soup, and an octagonal STOP that
wraps the existing <estop> SVG.
- Vue.config.async = false to fix sticky :class bindings under hash
navigation.

Rather than rebuild gplan + the AVR firmware to add a true 7th axis,
we treat W as a synchronous out-of-band axis that moves between G-code
blocks. The pipeline:
upload -> AuxPreprocessor rewrites W tokens into (MSG,HOOK:aux:N)
comments -> planner sees only XYZ + messages -> Hooks fires the
registered internal handler -> AuxAxis sends STEPS/HOME over serial
to the ESP and blocks the planner until done.
New files:
src/py/bbctrl/AuxAxis.py serial worker + RPC layer
src/py/bbctrl/AuxPreprocessor.py G-code rewriter
docs/AUX_W_AXIS.md design + ops notes
Changed:
Hooks.py register_internal(); fix the (MSG,HOOK:...) listener
to read the 'messages' state list (was broken before)
Ctrl.py instantiate AuxAxis, register aux/aux_rel/aux_home/
aux_setzero hooks
FileHandler.py rewrite uploads in place when they use W
Mach.py rewrite W tokens in MDI input the same way
Web.py REST endpoints under /api/aux/*
The ESP firmware in ../auxcnc was extended in lockstep: HOME, HOMECFG
(NVS-persisted), WPOS, HOMED?, LIMIT?, abortable STEPS with
limit-aware abort, trapezoidal ramps, deterministic [topic] reply
tokens, [boot] banner.
Real-time decisions (limit switch, step pulses) live on the ESP. The
host owns mm units, soft limits, and aux_homed bookkeeping. ESP
reboot mid-job clears aux_homed and surfaces a message; per design
manual jogs are still allowed without homing.
Use balenalib/raspberry-pi-debian:stretch with legacy.raspbian.org repos.
Exact match: GCC 6.3, Python 3.5, GLIBC 2.24 — identical to the Pi.
First build ~25min (QEMU), subsequent builds ~1sec (cached image).
Replaces the broken Bullseye approach that had GLIBC/GLIBCXX mismatches.
- New Hooks module (src/py/bbctrl/Hooks.py) that watches controller state
and fires webhooks or scripts on events:
- tool-change (M6), program-start, program-end, pause, estop,
homing-start, homing-end, custom (via MSG comments)
- API endpoints:
- GET /api/hooks - get current hook config
- PUT /api/hooks/save - save hook config
- PUT /api/hooks/fire/<event> - manually fire a hook (for testing)
- Hook config stored in hooks.json with two types:
- webhook: HTTP POST/PUT to external URL with JSON context
- script: run local command with env vars (HOOK_OLD_TOOL, etc.)
- Fix tornado.web.asynchronous deprecation in Camera.py
- Wired into Ctrl initialization and state listener system
