+# Getting Started with 3D Print Farm
+
+## Printer Setup: Bambu Lab A1
+
+### Initial Configuration
+- Calibrate bed (auto-leveling)
+- Load PLA filament
+- Set up Bambu Studio connection
+
+### Recommended Settings (PLA)
+- Nozzle temp: 200-210°C
+- Bed temp: 60°C
+- Print speed: 50-100mm/s
+- Layer height: 0.2mm (balanced quality/speed)
+
+### Maintenance Schedule
+- **Daily:** Check first layer adhesion
+- **Weekly:** Clean build plate, check nozzle
+- **Monthly:** Lubricate rails, check belts
+
+## Shopping List
+
+### Spare Parts Needed
+- [ ] Spare hotend (Bambu A1 compatible)
+- [ ] Extra feed tubes
+- [ ] Nozzles (0.4mm, 0.6mm)
+- [ ] Build plates (smooth PEI)
+
+### Filament Inventory
+- [ ] PLA: Black, White, Gray (1kg spools)
+- [ ] PETG: (for functional parts)
+- [ ] TPU: (for flexible parts - optional)
+
+## Workflow Tips
+
+1. **Test every new design** - Print one sample before production
+2. **Document settings** - Save successful profiles
+3. **Keep it organized** - Version control everything
+4. **Quality over speed** - Better to deliver great prints
