Pi's onboard chromium is 72 (Jan 2019). Two issues:
1. Python 3.5's mimetypes doesn't know woff/woff2/ttf, so Tornado
serves them as application/octet-stream which chromium 72 refuses
to use as web fonts -> all FA6 icons render as empty boxes. Add
scripts/deploy/patch_font_mime.py that monkey-patches bbctrl
Web.py's StaticFileHandler with correct content types. Run
automatically by deploy-hardware.sh (idempotent).
2. flex-gap landed in chromium 84. Add '> * + *' margin fallbacks
for the flex containers that show up on Program tab (action-bar,
action-btn, file-bar, file-btn) and tighten the kiosk-mode
settings rail so all 14 items fit in 768px height.
home() previously matched the wrong [home] line (firmware-side bug,
fixed in auxcnc) and even when it would have matched, it tried to
shift the step counter by writing 'WPOS <n>' after homing. The ESP's
WPOS handler clears HOMED, so a bbctrl restart would forget the home
state.
Push the desired step counter via HOMECFG zero= (firmware writes it
into the counter at the end of a successful HOME, leaving HOMED set).
home() now only reads the terminal [home] line; no post-home counter
fixup.
Round-3 cold-boot trims:
- mask sysstat.service (sadc CPU/IO logger; nothing reads it).
- mask dphys-swapfile.service and add /var/swap to /etc/fstab so swap
is brought up by systemd at local-fs.target instead of by an LSB
wrapper that re-checks the swap file size on every boot.
Both are reversible: `systemctl unmask <unit>` and remove the fstab
line. Before doing the dphys swap, install.sh verifies /var/swap
exists; on a fresh image where the file hasn't been created yet,
nothing is changed and dphys-swapfile keeps running normally.
Userspace boot 11.5s -> 10.7-11.4s on clean runs; bbctrl listen
unchanged at boot+10.4s (the saving moves to chromium/multi-user).
Persist the cold-boot wins (was: only manually deployed via
tmp/20260501_restart_timing/deploy-fast.sh, would silently revert on
the next prod firmware update).
- Install bbserial-rebind.service alongside bbctrl.service and enable
it. Eliminates the rc.local bbserial reload mid-boot.
- Prefer scripts/rc.local.fast over scripts/rc.local when present.
Legacy rc.local left as a fallback for old firmware tarballs.
- Mask plymouth-read-write, plymouth-quit-wait, and raspi-config.
Together these were ~6s of userspace startup that bought nothing
on a deployed Onefinity Pi.
Cumulative: bbctrl listening at boot+10.6s (was 20.6s), userspace
boot 11.5s (was ~13s), bbctrl.service @2.9s in critical-chain (was
@6.5s after the first optimisation pass).
Measured on onefinity.local (Pi 3, Raspbian Stretch, bbctrl 1.6.7).
Before -> after:
bbctrl listen boot+20.6s -> boot+12.4s (-8.2s)
host -> /api/config/load 28.2s -> 22.5s (-5.7s)
The 4 changes (each independently revertable):
1. scripts/bbserial-rebind.service: do the bbserial unbind + reload
in a dedicated unit ordered Before=bbctrl.service, instead of in
rc.local AFTER bbctrl is already listening on the serial port.
Eliminates a full bbctrl restart mid-boot.
2. scripts/bbctrl.service: drop "After=network.target". bbctrl talks
to the AVR on a local serial port and to the LCD on I2C; it does
not need DHCP / network-online to come up. Also adds explicit
ordering after the new bbserial-rebind unit.
3. scripts/rc.local.fast: trimmed rc.local that no longer touches
bbserial and backgrounds 'startx' so chromium launches in
parallel with bbctrl rather than after rc.local finishes.
4. src/py/bbctrl/Planner.py: lazy-import camotics.gplan. Costs ~130ms
on cold cache, deferred from import-time to ctrl.mach init.
5. (bonus) src/py/bbctrl/Log.py: tolerate FileNotFoundError in
_rotate(). The improved boot path exposed a pre-existing log
rotator bug that crashed bbctrl on first start when bbctrl.log.16
was missing.
- Trace reads /proc/stat btime and /proc/uptime at import so every
event in /api/diag/timing can be expressed as 'seconds since
power-on' (uptime_at_anchor + ev.t).
- Web.StaticFileHandler.prepare emits 'web.first_root_get' the first
time chromium hits / or /index.html, so we can see when the kiosk
browser actually started loading the UI on cold boot.
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.
The bbctrl controller seeds new macros with placeholder colors like
'#dedede' and '#ffffff'. Treating those as 'configured' lit up the
asymmetric 6 px left stripe on every default macro, which looked
lopsided.
Add control-view.has_macro_color() that filters out a fixed set of
default placeholders plus anything within the near-white band
(R+G+B > 690). The .has-color class and the inline border-left-color
style are gated on that helper, so unconfigured macros render as
clean symmetric slate tiles.
Tested live on http://10.1.10.55/#control with the existing macro
config (#dedede): button now renders without the gray stripe.
After testing the V09 redesign live on the Pi at onefinity.local
(1920x1080, Chrome fullscreen) several real bugs surfaced. This
commit fixes all of them.
Layout fits at 1920x1080
- Cap .app-shell at 100vh height with overflow:hidden so child
flex containers actually constrain to one screen.
- Make .control-page / .program-page / .console-page use
flex 1 1 auto + min-height 0 + overflow hidden so the page total
no longer grows to ~36 000 px when the gcode-viewer is mounted.
- Override clusterize.css default max-height: 200px on the
.clusterize-scroll element with max-height: none + flex 1 1 0 +
height 100% so the gcode listing fills the available column.
E-Stop in the header
- The legacy estop.pug SVG had width=130 height=130 but no
viewBox, so CSS-only sizing did nothing and the SVG content
spilled ~26 px off the right edge of the screen and ~70 px
below the header. Add viewBox="0 0 130 130" plus
preserveAspectRatio so CSS sizing actually shrinks the inner
geometry. Drop the octagonal clip-path (the SVG already
carries its own yellow safety ring + EMERGENCY/STOP text).
3D toolpath preview (path-viewer)
- The legacy .path-viewer.small CSS clamped the canvas to
340 x 150 floated into the corner. In the new program-body
grid we want it to fill the 600 px right column. Override
with width 100%, height auto, float none, !important.
- Make orbit.js wheel/touchstart/touchmove listeners
{passive: false} so OrbitControls.preventDefault() actually
works and the page no longer scrolls while panning the 3D
view on a touch screen.
Vue 1 template + reactivity bugs exposed by the live data
- Replace v-else-if (Vue 1 has no v-else-if) in
control-view.pug with three sibling v-if templates that
mutually exclude on w.enabled and state['2an'] == 3.
- axis-vars._get_motor_id: guard motor.axis.toLowerCase()
against undefined motors (initial config is [{}, {}, ...]).
- axis-vars._check_is_enabled: prefer config.motors[i].axis
when present, fall back to state[N + 'an'] only for
recognised axes (x/y/z/a) so undefined == undefined
doesn't mistakenly enable b/c rows.
- program-mixin: tolerate state.files / state.gcode_list
being undefined right after connect.
App-shell race conditions
- Skip the early parse_hash() in app.js ready() when the
initial hash is in the settings family. Those Svelte
components read settings.units / settings.probing-prompts /
motion.* etc. and crash on first paint with the empty
placeholder config. Stay on loading-view until update()
completes and routes us in itself.
Misc
- src/static/js/ui.js: null-guard the legacy burger menu code
(#menuLink no longer exists). Was throwing 'Cannot set
properties of null (setting onclick)'.
- src/static/css/Audiowide.css: switch the gstatic font URL
from http:// to https:// so it isn't blocked as mixed
content under the home.muehe.org HTTPS proxy.
- Macro buttons: drop the default 6 px yellow border-left.
The stripe now only appears via .has-color when
state.macros[i].color is actually configured. Removes the
asymmetric/lopsided look from the screenshot.
Tested live on http://10.1.10.55/ and via the HTTPS proxy at
https://onefinity.home.muehe.org/.
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).
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.
# Conflicts:
# .gitignore
Implements the V09 mock end-to-end (per plans/2026-04-30_ux_redesign.md):
Top shell
- index.pug rebuilt around .app-shell with a slim 96px header.
- Underline-ribbon tab bar (Control / Program / Console / Settings)
replaces the old side menu and the inline #tab1..#tab4 system.
- Single 'All systems' pill collapses the legacy WiFi/Camera/Rotary/
IP/Version chip-soup into one popover (sys-popover) anchored to the
header; rotary toggle, camera feed and shutdown live there.
- Octagonal 88x88px STOP button wraps the existing <estop> SVG; STATE
pill with pulse-dot honors prefers-reduced-motion.
Routing
- app.js parse_hash maps every existing hash:
#control -> Control
#program / #program:auto -> Program
#console / #console:mdi|messages|indicators -> Console
#settings, #admin-general,
#admin-network, #motor:N, #tool, #io, #macros, #help,
#cheat-sheet -> Settings (rail picks inner)
- All deep links are preserved.
Control panel (control-view.pug + .js)
- 720px jog grid + 4-axis DRO + 4 KPI cards + 8-macro row.
- Jog tiles use V09 flat slate (#3f4b63) with diagonal helpers and
a ghost row for XY/Z origin shortcuts.
- Per-axis Settings/Set-zero/Home buttons grow to 72x72px.
- Status strip cards: State / Velocity-Feed / Spindle / Job. Tapping
the Spindle card opens the new override-drawer with feed + spindle
range inputs (resolved decision in plans/...).
- Macro row binds to state.macros.slice(0, 8); >8 lives in Settings.
- Drops the old <table> control-buttons, .info, .override and .tabs
blocks entirely.
Program panel (program-view.pug + .js)
- Extracts the Auto bar, file selectors, gcode-viewer and path-viewer
out of control-view.
- Action buttons (RUN/STOP/UPLOAD-FOLDER/UPLOAD-FILE/DOWNLOAD-FILE/
DELETE) at 84px with explicit color affordances.
- Reuses control-view's existing methods via the new program-mixin.
Console panel (console-view.pug + .js)
- Three sub-tabs: MDI / Messages / Indicators. Sub-tab persists in the
URL fragment (#console:messages etc.).
- MDI: terminal-style prompt + SEND, plus an 8-wide on-screen keypad
(G0/G1/G2/G3/G28/G92/M3/M5 + axis letters + CLEAR/SEND).
- Messages: pulls from .messages_log (mirrored from
state.messages); badge in the header tab counts unread.
- Indicators: mounts the existing <indicators> component.
Settings shell (settings-shell.pug + .js)
- New left rail navigator listing Display, Network, General/Firmware,
Spindle&Tool, IO, Motors 0..3, Macros, Cheat Sheet, Help.
- Inner area mounts the existing settings family templates via an
explicit v-if cascade (avoiding a Vue 1 :is reactivity quirk).
- Shutdown / Save buttons relocated from the dropped side menu.
JS plumbing
- main.js: Vue.config.async = false to keep dependent watchers in
sync when reactive data is mutated outside Vue's normal event loop
(e.g. from a hashchange listener).
- program-mixin.js extracted so control-view.js no longer carries the
file/macro/gcode methods that are now Program-only.
- control-view.js trimmed to jog/DRO/probe/home logic.
- console-view.js / settings-shell-view.js use a hashchange listener
+ local data props because Vue 1 cannot reliably observe
.sub_tab from a child component.
Stylus rewrite
- Removes the old .header (140px), .nav-header, .brand subtree, #menu,
#main, .control-view block, .info, .override, .toolbar, .macros-div,
.macros-button, the .tabs > input radio-tab system and the .control-
view #control media-query overrides. None of these are referenced
any more.
- Adds V09 tokens (jog/macro palette + accent + line/card colors) at
the top, the new shell rules, .ktab / .sys-btn / .state-badge /
.estop chrome, the .control-page grid, status strip + override
drawer, .program-page action / file bars and program body,
.console-page MDI keypad / messages / indicators panes, and the
.settings-shell rail.
- Adds a 1820px breakpoint that stacks the right column under the jog
on smaller portable monitors.
Hard cut: no config.ui.layout flag, the old shell is removed in this
single commit. side-menu.css is no longer included from index.pug.
Tested locally with agent-browser (1920x1080) on every top tab and
every settings sub-route; routing, active tab highlighting and inner
view selection all work without a controller connection.
Replaces the 'Open questions' section with 'Resolved decisions' and
propagates the four decisions into the relevant phases:
- Hard cut: no config.ui.layout flag. Phase 6 now includes the
removal of .nav-header, side-menu.css and the #tab1..#tab4 block
with a git grep verification step.
- Macros: Control row binds to config.macros.slice(0, 8); Settings
-> Macros owns the master list and reordering.
- Pin to Control: deferred, status strip stays at State / V&F /
Spindle / Job for this iteration.
- Feed/spindle override: bottom drawer triggered by the Spindle
KPI tile, reusing override_feed / override_speed.
Goals (s.1) and Phase 6 testing checklist updated to match.
- docs/mocks/v09_full_ux.html — high-fidelity 1920x1080 mock
showing the proposed Control / Program / Console / Settings tab
layout with the V09 flat slate jog/macro palette and an underline
ribbon header tab style.
- plans/2026-04-30_ux_redesign.md — phased implementation plan to
port index.pug + control-view.pug to the new shell while keeping
hash routing and existing settings/admin views intact.
- README.md (was a one-liner): describe the layout, the macOS quick
path including the esbuild platform-pin gotcha, and how to flash
with curl or 'make update'.
- docs/AUX_W_AXIS.md: document the new Control jog row layout, the
Settings 'W Axis (auxcnc)' section, and list the additional UI
files touched by this fork.
Expose the aux.json fields under a new 'W Axis (auxcnc)' section in
Settings: serial port/baud, mechanics (steps/mm, dir sign, soft limits,
max feed), homing (direction, position, fast/slow seek, backoff, max
travel, limit polarity) and the step profile (max/start rate, accel).
The 'enabled' flag stays read-only in the UI; flipping the W axis
on/off is still done via aux.json so a fresh install can't surprise the
user with hardware that isn't there. Live status (offline / unhomed /
homed at <pos> mm) is shown above the form.
Saving PUTs the merged config to /api/aux/config/save, which writes
aux.json and pushes the homing/step config to the ESP.
The W axis homing already drives toward the configured limit (home_dir
in aux.json, default '-') and lands at home_position_mm = 0, so
'home' and 'zero' are the same point. Remove the now-redundant 'W
Origin' (move-to-zero) and 'Set W to 0' map-marker buttons; keep just
W-, W+, and a single Home W button. Also drop the unused
aux_move_zero / aux_set_zero JS handlers.
Mirrors the 4-column rotary A row that appears when 2an==3, so the same
fine/small/medium/large increment selector that drives XYZ jogging now
also drives W jogging. New control-view methods:
- aux_jog_incr(sign) - PUTs aux/jog with the current jog_incr amount
converted to mm (handles imperial display units)
- aux_move_zero() - PUTs aux/move {mm:0}, the absolute counterpart to
aux_set_zero (which redefines the current pos as zero without moving)
Row is hidden when w.enabled is false, so users without the auxcnc
controller see no change.
The xyzabc rows have three actions (set-position cog, zero marker, home),
W only has two. Without a placeholder the W buttons render in the left two
slots of the actions cell, leaving the home button unaligned with the home
column above. Added a hidden disabled cog button so the marker and home
buttons sit under the same columns as the rest.
Adds the auxcnc W axis to the front-page Position table:
- axis-vars.js exposes a 'w' computed property fed by state.aux_pos /
aux_enabled / aux_homed / aux_present (set by AuxAxis on the host).
No motor mapping, no soft-limit warnings - the aux controller does
its own bounds.
- control-view.pug adds a W row after the xyzabc loop. The Set/Zero
button calls /api/aux/set-zero {mm:0} and the Home button calls
/api/aux/home, which hit the new endpoints exposed by Web.py.
- control-view.js: aux_home(), aux_set_zero(), and aux_jog() helpers.
When aux_enabled is false (no aux.json or aux.json has enabled=false)
the row stays hidden, matching the existing axis-row behavior.
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.
The gplan.so (CAMotics G-code planner) must be a 32-bit ARM binary
matching the Pi's Python 3.5. Source it from the official release
package rather than cross-compiling (SCons ignores CC/CXX overrides).
Also revert install.sh gplan.so preservation logic — simpler to just
ship the correct binary in the package.
- Blocking hooks (block_unpause: true, default for tool-change) run
in a background thread and gate Mach.unpause() via can_unpause()
- Machine stays in HOLDING state while hook runs — AVR steppers idle,
spindle state preserved, position locked
- auto_resume option to unpause automatically after hook completes
- E-stop cancels any running hook immediately
- Hook status pushed to frontend via state (hook_busy, hook_event)
- GET /api/hooks/status endpoint for polling
- Non-blocking hooks (program-start, program-end, etc.) fire-and-forget
- 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
