+
+### Accessories
+- Creality Hardened Steel MK8 Nozzles (5-pack)
+
+## Remote Printing Infrastructure
+
+### Raspberry Pi 3 B+ (`seth-pi`)
+- **Hostname:** seth-pi
+- **OS:** Debian 13 (Raspberry Pi OS Lite)
+- **User:** seth (key-only SSH, no root login)
+- **wlan0:** 192.168.0.102 (main network, DHCP) — default route
+- **eth0:** 192.168.0.101/24 (isolated camera router subnet)
+- **WiFi SSID:** WiFrei
+
+### OctoPrint
+- **URL:** http://octopi.sethpc.xyz (port 5000 on Pi)
+- **API key:** see `octopi.sethpc.xzy_api_key.md`
+
+### go2rtc (v1.9.14)
+Restreams both cameras with H.264 hardware transcoding and MJPEG fallback.
+- **API:** http://192.168.0.102:1984
+- **RTSP:** rtsp://192.168.0.102:8554
+- **Streams:**
+  - `cam1` / `cam1_mjpeg` — Camera 1 (192.168.0.100)
+  - `cam2` / `cam2_mjpeg` — Camera 2 (192.168.0.103)
+
+### IP Cameras — TENVIS (on isolated eth0 subnet)
+Both TENVIS cameras use credentials `admin:admin` and expose RTSP on port 554 (`/11` path), HTTP on 80, and ONVIF on 8080.
+- **Internal model:** C9F0SeZ0N0P4L0 (Hi3510-based SoC)
+- **Firmware:** V9.1.6.1.24-20170925
+- **Hardware version:** V1.0.0.1
+- **CGI interface:** `/cgi-bin/hi3510/param.cgi`
+- **cam2 has an SD card inserted** (59GB)
+
+| Camera | Isolated IP | Proxy Ports (on .102) |
+|---|---|---|
+| cam1 | 192.168.0.100 | HTTP:18080, ONVIF:18081, RTSP:18554 |
+| cam2 | 192.168.0.103 | HTTP:28080, ONVIF:28081, RTSP:28554 |
+
+### Proxy Architecture
+The Pi bridges two networks:
+- **eth0** (192.168.0.101) connects to an isolated router with the two IP cameras
+- **wlan0** (192.168.0.102) connects to the main homelab network
+- **socat** systemd services proxy each camera port from the isolated subnet to the main network
+- Port scheme: `1xxxx` = cam1, `2xxxx` = cam2
+
+Proxy services (all systemd, auto-restart):
+- `ipcam-proxy-http.service` — 18080 -> 192.168.0.100:80
+- `ipcam-proxy-onvif.service` — 18081 -> 192.168.0.100:8080
+- `ipcam-proxy-rtsp.service` — 18554 -> 192.168.0.100:554
+- `ipcam2-proxy-http.service` — 28080 -> 192.168.0.103:80
+- `ipcam2-proxy-onvif.service` — 28081 -> 192.168.0.103:8080
+- `ipcam2-proxy-rtsp.service` — 28554 -> 192.168.0.103:554
+
+## Camera Control Panel
+- **URL:** http://192.168.0.220:8090
+- **Location:** `/opt/cam-control/server.py` on CT 241 (Frigate)
+- **Service:** `cam-control.service` (systemd, enabled)
+- **Features:** Live MJPEG feeds, PTZ D-pad (continuous/step), speed control, flip/mirror toggles
+- **Source:** `./cam-control/server.py`
+
+## Gitea
+- **Repo:** https://git.sethpc.xyz/Seth/3d-printing
+- **Remote:** `https://Seth:REDACTED_GITEA_TOKEN@git.sethpc.xyz/Seth/3d-printing.git`
+
+## Conventions
+- Camera credentials: admin/admin (default, isolated network only)
+- Pi SSH: key-only as `seth`, no password auth
+- Internal password for homelab services: REDACTED_PASSWORD
