Calibration
Reusable print-to-cut calibration profiles and physical test evidence
Existing puzzle exports are unchanged. Future final exports must explicitly opt in to confirmed profiles and store frozen correction snapshots.
Cut Spacing Ladder
Hidden proof for checking tighter cut spacing. Production spacing is unchanged.
| Target | Actual cut spacing | Bleed gap |
|---|---|---|
| 2.95 mm | 2.954 mm | 1.153 mm |
| 2.75 mm | 2.753 mm | 0.953 mm |
| 2.50 mm | 2.503 mm | 0.703 mm |
| 2.25 mm | 2.254 mm | 0.453 mm |
| 2.00 mm | 2.004 mm | 0.203 mm |
| 1.80 mm | 1.804 mm | 0.006 mm |
