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
