# SESSION.md — 3D Printing Project
|
|
|
|
## Context Files
|
|
|
|
- `./CLAUDE.md` — full project docs (printer, cameras, Pi, Frigate, cam-control, PTZ commands)
|
|
- `./CONTEXT.md` — raw hardware purchase inventory (Amazon order data)
|
|
- `./GITEA_API.md` — Gitea push credentials and commit convention
|
|
|
|
## Project Summary
|
|
|
|
3D printing setup with one Creality Ender 3 V3 SE, remotely managed via OctoPrint on a Raspberry Pi 3 B+. Two TENVIS IP cameras on an isolated router subnet are proxied through the Pi (socat) and fed to Frigate NVR + a custom PTZ control webapp. Timelapses stored on tank (node-173) via SMB.
|
|
|
|
## Memory Discipline
|
|
|
|
- Update `SESSION.md` immediately when a durable fact, decision, or fix is discovered.
|
|
- Before every final reply, run a memory check and append any missing durable notes.
|
|
- End every reply with one line: `Session memory: updated` or `Session memory: no new durable facts.`
|
|

## Session Notes
|
|
|
|
### Initial setup (2026-03-17)
|
|
- Created SESSION.md from template in SESSION.default.md
|
|
- Organized CONTEXT.md inventory data into structured hardware/filament tables
|
|
|
|
### Camera/Pi discovery (2026-03-24)
|
|
- Pi 3B+ (`seth-pi`) found at 192.168.0.102 (wlan0) / 192.168.0.101 (eth0)
|
|
- eth0 connects to isolated router with 2 IP cameras (192.168.0.100, 192.168.0.103)
|
|
- 6 socat proxy services bridge camera HTTP/RTSP/ONVIF to main network
|
|
- go2rtc v1.9.14 restreams both cameras (H.264 hw + MJPEG)
|
|
- OctoPrint running on port 5000
|
|
- Camera creds: admin/admin (default, isolated subnet)
|
|
- Created CLAUDE.md with full infrastructure documentation
|
|
- [x] Document OctoPrint setup — done, documented in CLAUDE.md
|
|
- Camera make: TENVIS (both cameras)
|
|
|
|
### Frigate NVR setup (2026-03-24)
|
|
- Added both cameras to Frigate 0.17 on CT 241 (192.168.0.220)
|
|
- Config at `/opt/frigate/config/config.yml`, docker-compose at `/opt/frigate/docker-compose.yml`
|
|
- Added port 1984 mapping to docker-compose (go2rtc API, needed for cam-control)
|
|
- Streams: `printer_cam1`, `printer_cam2` — pulled from Pi socat RTSP proxies
|
|
- Object tracking disabled, CPU detector only
|
|
- Gotcha: Frigate 0.17 changed record config schema — no `retain.days` or `events`, use `continuous.days`/`motion.days`
|
|
|
|
### Camera control panel (2026-03-24)
|
|
- Built single-page PTZ control webapp (`cam-control/server.py`)
|
|
- Deployed to Frigate CT 241 at http://192.168.0.220:8090
|
|
- systemd service `cam-control.service` enabled and running
|
|
- Features: snapshot-polled live feeds (~5fps), PTZ D-pad, speed, flip/mirror
|
|
- Uses Frigate's go2rtc frame.jpeg endpoint (not MJPEG stream — MJPEG proxy through Python urllib doesn't work reliably)
|
|
- Must use ThreadingMixIn — single-threaded HTTPServer blocks on stream connections
|
|
- cam2 flipped 180 (flip=on, mirror=on)
|
|
|
|
### OctoPrint timelapse fix (2026-03-24)
|
|
- Pi fstab pointed to pve197 for tank SMB — updated to node-173 post-migration
|
|
- Created octoprint Samba user on node-173 (creds: octoprint/octoprint)
|
|
- Timelapses dir at /tank/Timelapses now accessible, OctoPrint restarted
|
|
|
|
### Gotchas & Lessons Learned
|
|
- Pi's go2rtc API binds to `127.0.0.1` only — not accessible remotely. Use Frigate's go2rtc instead.
|
|
- Pi's wlan0 is DHCP (192.168.0.102 last seen) — may change. Use `nmap -sn 192.168.0.0/24 | grep Raspberry` from a node to find it.
|
|
- Pi SSH is key-only as `seth` — reachable via `ssh seth-pi` from steel141, or hop through pve197.
|
|
- MJPEG streaming through Python urllib is unreliable (0 bytes returned) — use snapshot polling (frame.jpeg) instead.
|
|
- Frigate 0.17 config schema differs from older docs online — query the Python schema if unsure: `docker exec frigate python3 -c 'from frigate.config import FrigateConfig; ...'`
|
|
- OctoPrint SMB mount must point to wherever tank lives (currently node-173 at .173). If tank moves again, update Pi fstab.
|
|
- Caddy config for `octopi.sethpc.xyz` is on CT 600 (192.168.0.185) at `/etc/caddy/Caddyfile` — includes camera stream rewrites at `/cam1.mjpeg`, `/cam2.mjpeg`, `/cam1.jpg`, `/cam2.jpg`.
|
|
|
|
### Open threads
|
|
- [ ] Add slicer profiles and recommended print settings per filament type
|
|
- [ ] Change default camera passwords (admin/admin) — update in: go2rtc.yaml (Pi), Frigate config, cam-control server.py
|
|
- [ ] Make Pi wlan0 IP static (currently DHCP, could change)
|
|
- [ ] Fix Pi's go2rtc to bind to 0.0.0.0 if remote MJPEG streaming is ever needed
|
|
- [ ] OctoPrint config location unknown — not at default `/home/seth/.octoprint/`. Find with: `find / -name config.yaml -path '*octoprint*'` — it's at `/home/octoprint/.octoprint/` (runs as `octoprint` user, venv at `/home/octoprint/venv/`)
|
|
|
|

|
|
- [x] Add cameras to Frigate NVR
|
|
- [x] Build PTZ camera control webapp
|
|
