# SESSION.md — 3D Printing Project

## Context Files

- `/root/bin/core_homelab.md` — cluster topology, SSH aliases
- `/root/bin/services_directory.md` — active service IPs and domains
- `/root/bin/SESSION.md` — global session memory
- `./CONTEXT.md` — printer hardware, filament inventory, and accessories
- `./GITEA_API.md` — Gitea push credentials and commit convention

## Project Summary

3D printing setup and management for a Creality Ender 3 homelab. Covers two printers (Ender 3 V3 SE and Ender 3 S1 Pro), filament inventory across PLA/PETG/ABS in multiple colors, and hardened steel MK8 nozzles. The CONTEXT.md file serves as an inventory of purchased hardware and consumables.

## 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)

### 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: dual MJPEG feeds via go2rtc, PTZ D-pad, speed, flip/mirror

### 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

### Open threads
- [x] Identified camera: TENVIS, internal model C9F0SeZ0N0P4L0 (Hi3510 SoC), firmware V9.1.6.1.24-20170925
- [ ] Add slicer profiles and recommended print settings per filament type
- [ ] Set up Gitea repo and push project files
- [ ] Change default camera passwords (admin/admin)
