Add a lightweight, self-contained phase tracer for measuring end-to-end
bbctrl restart and Pi boot time. Disabled by setting BBCTRL_TRACE=0.
- src/py/bbctrl/Trace.py: monotonic-anchored event log + sd_notify helper.
- bbctrl/__init__.py: marks for imports, args parsed, ioloop, web init,
listen, and an sd_notify READY=1 once HTTP is bound.
- bbctrl/Ctrl.py: spans around each subsystem (avr, i2c, lcd, mach,
preplanner, jog, pwr, hooks, aux, mach.connect).
- bbctrl/Comm.py: avr.firmware_rebooted mark.
- bbctrl/Web.py: TimingHandler (GET /api/diag/timing) and
UITimingHandler (PUT /api/diag/timing/ui), plus a ws.first_open mark.
- src/js/restart-timing.js + app.js: UI-side performance.now() marks
(script.load, ws.open, ws.first_msg, ui.first_state, window.load),
posted once to the controller.
- scripts/bbctrl.service: stdout/stderr -> journal so TRACE lines are
visible via journalctl -u bbctrl. (Was StandardOutput=null.)
Revert: git revert this commit. To disable at runtime without
reverting, set BBCTRL_TRACE=0 in the bbctrl service environment.
UX
- The V09 redesign already exposed the W axis in the Control jog grid
(row 4 when w.enabled) and as a row in the DRO table. The Settings
shell now also surfaces a dedicated 'W Axis' rail entry that smooth-
scrolls to the W Axis (auxcnc) section of the main settings page.
The rail item is marked active only while the user is on Display &
Units AND the W Axis link was the most recent click.
- The W Axis section in src/svelte-components/src/components/Settings
View.svelte gets an id="w-axis" anchor so the scroll lands cleanly.
Tested live against onefinity.local. Aux status reports
{enabled: true, present: true, pos_mm: 43.96, homed: false}; the W
axis row appears in the DRO with the right purple styling, and the
jog row 4 shows W- / Home W / W+ / Probe.
Deploy scripts
- deploy.sh dispatches to scripts/deploy/{local,hardware,prod}.sh
with shorthand wrappers (deploy-local.sh / deploy-hardware.sh /
deploy-prod.sh).
- local: builds the UI bundle and serves build/http/ via
python3 -m http.server 8770 in a tmux session 'onefin-local'.
Useful for visual iteration on macOS — chrome only, no controller.
- hardware: rsyncs the freshly built build/http/ tree onto the Pi at
onefinity.local and restarts bbctrl. Stages to /tmp on the Pi and
uses sudo to install into the running egg's bbctrl/http directory,
so iteration time is ~5 seconds.
- prod: requires a clean working tree, then runs 'make pkg' followed
by 'make update HOST=onefinity.local PASSWORD=onefinity'.
Defaults can be overridden with environment variables (HOST, PASSWORD,
REMOTE_USER for the hardware path).
