Design proposal for review - Redmine #855 in the new STLP Shop Manager sub-project (child of TSYS Software Stack), repo: StartingLineProductions.com/STLPShopManager (docs/design.md has the canonical copy).
Goal
Run the SLP shop as a production system: Etsy orders flow through Dolibarr into managed print / laser / CNC / reflow jobs, with completion flowing back. One dashboard, Cloudron-deployable, platform OIDC SSO, single Go binary (no Node anywhere).
Managed device classes
| Class | Controllers | Adapter |
|---|---|---|
| FDM printers | Klipper/Moonraker, OctoPrint, Bambu (MQTT) | moonraker / octoprint / bambu |
| Reflow oven | Whizoo controller (profiles; serial/MQTT bridge v2) | reflow |
| Laser (CR-10 conversion) | GRBL | grbl-laser |
| CNC (CR-10 conversion) | GRBL | grbl-cnc |
Reflow: the manager owns the profile library (paste-specific temperature curves, versioned), run logging (actual vs target), and serial/MQTT start/monitor as phase 2. Laser + CNC share one GRBL adapter with separate material/tool profiles.

Phasing
- MVP-1: dashboard + FDM adapters (Moonraker/OctoPrint) + manual queue + OIDC + ntfy + Cloudron package
- MVP-2: GRBL adapter + laser/CNC job management + profile libraries + Dolibarr connector
- MVP-3: reflow profile library + run logging + Whizoo bridge, batch automation, QA checklists, Prometheus
Work tracking
Sub-project STLP Shop Manager carries the full breakdown: scaffold is live (#855 = MVP scaffold pushed), work items #908-#918 (core engine, adapters, Dolibarr connector, OIDC, dashboard, alerts, Cloudron package), plus #854 OrcaSlicer, #853 CAMotics, #859 stencil pipeline, #878 lto-bms, #905 embedded firmware - all on the Potential to Kinetic Ready milestone.
Open questions: printer fleet inventory at launch, Dolibarr API version + farmd API key provisioning, name confirmation (farmd as the binary, STLP Shop Manager as the product).
