3d Printing

2. Choose Presets

List available presets:

list_presets("all")

Common filament presets:

• pla_basic - Standard PLA settings
• pla_plus - Enhanced PLA for better layer adhesion
• petg_standard - PETG with typical settings
• petg_strong - Higher temp PETG for strength
• abs_standard - ABS with enclosure settings
• tpu_flexible - TPU for flexible prints

Common quality presets:

• draft - 0.3mm layer, fast printing
• standard - 0.2mm layer, balanced
• fine - 0.12mm layer, detailed
• ultra_fine - 0.08mm layer, maximum detail

3. Slice the Model

slice_model(
  model_path="/path/to/model.stl",
  filament_preset="pla_basic",
  quality_preset="standard",
  output_description="benchy test print"
)

This will:

1. Load the model and presets
2. Slice using OrcaSlicer CLI
3. Save to ~/.casterly/prints/YYYY-MM-DD_description/
4. Store both original model and generated gcode

4. Upload and Print

Upload the sliced gcode:

upload_to_printer("/path/to/output.gcode")

Start the print:

start_print("output.gcode")

5. Monitor Progress

Check status anytime:

check_print_status()

Returns:

• Print state (printing, paused, idle, error)
• Progress percentage
• Estimated time remaining
• Current layer
• Temperatures (bed, nozzle)

Managing Presets

Create a new filament preset

save_preset(
  preset_type="filament",
  name="silk_pla",
  settings={
    "material": "PLA",
    "nozzle_temp": 215,
    "bed_temp": 60,
    "flow_ratio": 0.98,
    "retraction_length": 0.8,
    "retraction_speed": 35,
    "notes": "Silk PLA needs slightly higher temp"
  }
)

Create a new quality preset

save_preset(
  preset_type="quality",
  name="speed_draft",
  settings={
    "layer_height": 0.28,
    "first_layer_height": 0.3,
    "infill_percentage": 10,
    "wall_loops": 2,
    "top_layers": 3,
    "bottom_layers": 3,
    "print_speed": 150,
    "travel_speed": 250,
    "notes": "Fast draft for prototypes"
  }
)

Printer Control

Connection

The printer is accessed via its network API. Configure in 3d-printing.yaml:
