Quick-Reference Operator Card

1. Pre-Flight Safety & Prep Checklist

  • [ ] PROTECTIVE GEAR: Put on safety glasses when removing support structures or using flush cutters.
  • [ ] VENTILATION: Ensure the internal enclosure door is kept closed and filtration is active when printing ABS, ASA, or composite filaments.
  • [ ] BUILD PLATE PREP: Clean the flexible PEI plate with 99% Isopropyl Alcohol (IPA) and a lint-free wipe. (Never use metal scrapers on PEI surfaces).
  • [ ] CHAMBER CLEARANCE: Verify the build plate is seated flush against magnetic locators and the motion path is free of loose debris or purged plastic blocks.

2. Standard 5-Step Print Workflow

  1. MOUNT / VERIFY FILAMENT Load spools into the AMS unit or rear manual holder. Verify the desiccant pack inside the AMS is active (dry).
  2. SLICE IN BAMBU STUDIO Select the matching nozzle size (0.4\text{ mm} default) and filament profile. Verify overhang angles (\le 45^\circ) and enable tree supports if needed.
  3. SEND JOB & ASSIGN AMS SLOTS Click Print Plate. Map your slicer filament colors/materials to the corresponding AMS slot numbers.
  4. ENABLE AUTO-CALIBRATION Check Bed Leveling and Flow Dynamic Calibration for high-precision or critical first-layer prints.
  5. VERIFY FIRST LAYER Observe the prime line and complete first layer before stepping away.

3. Filament & Hardware Constraints

Filament Type AMS Compatible? Bed Temp Nozzle Temp Key Operational Rule
PLA / PLA-CF ✅ Yes 35^\circ\text{C} - 55^\circ\text{C} 210^\circ\text{C} - 230^\circ\text{C} Leave top glass lid vented to prevent heat creep.
PETG ✅ Yes 70^\circ\text{C} - 80^\circ\text{C} 230^\circ\text{C} - 250^\circ\text{C} Must be thoroughly dried; clean plate with IPA to ensure release.
TPU (Flexible) ❌ NO 30^\circ\text{C} - 50^\circ\text{C} 220^\circ\text{C} - 240^\circ\text{C} BYPASS AMS. Feed directly from rear spool holder.
ABS / ASA ✅ Yes 90^\circ\text{C} - 100^\circ\text{C} 250^\circ\text{C} - 270^\circ\text{C} Keep door and lid fully closed; enable internal air filter.

4. Rapid Troubleshooting & Maintenance

Symptom / Issue Cause Immediate Corrective Action
First Layer Lifting / Warping Finger oils on plate or incorrect bed temp. Wash PEI plate with warm water & dish soap, dry, then wipe with 99% IPA.
Extruder Clicking / No Extrusion Nozzle clog or heat creep. Heat hotend to 250^\circ\text{C} and perform a cold pull or unclog with needle.
AMS Filament Feed Error Brittle/swollen filament or guide tube drag. Inspect AMS funnel for broken filament bits; replace bent PTFE tubing.

⚠️ HOT SURFACE HAZARD: Nozzle (300^\circ\text{C}) and bed (100^\circ\text{C}) reach severe burn temperatures. Wait for the bed to drop below 40^\circ\text{C} before removing parts. Report mechanical noises, damaged PTFE tubes, or nozzle clogs to lab staff immediately.
