Save the final puzzle geometry as well as the generator seed if you want a replacement piece to match later. A seed can recreate a pattern only when the relevant generator behavior and other inputs remain the same. The exported file is the strongest starting point when the original puzzle already exists.
The maker's generated jigsaw project describes a seed that changes the arrangement of puzzle shapes. That feature is useful during design, but generating a visually similar new puzzle is not the same as recovering the exact outline of one missing piece.
Keep a small replacement record
Archive the accepted SVG, the original image, the overall dimensions, row and column counts, seed, tab settings and generator identity or version where available. Label the puzzle's orientation in a reference image. If possible, identify pieces by their row and column so a later request points to one location.
| Saved item for an A1-scale sample | Why it matters later |
|---|---|
| Final exported geometry | Preserves actual mating outlines |
| Generator inputs and seed | Explains how the geometry was created |
| Material thickness and sample | Helps assess physical fit |
| Compensation record | Separates design dimensions from toolpath changes |
| Assembled reference photo | Identifies location and artwork orientation |
Keep the original file unchanged and work from a copy for any replacement. If compensation has already been incorporated into its paths, avoid applying the kerf correction twice. A second offset can make a correct archived shape fit incorrectly.
Inspect the recovered outline before processing
Open the saved SVG and compare the selected piece with its neighbors. If the file will not load, resolve the SVG import error before rebuilding from memory or changing machine settings. A screenshot is useful for orientation but should not replace precise vector geometry when mating edges matter.
The A1 Mini has a 120 × 130 mm working area. The source project describes a larger whole puzzle; it is not evidence that the entire design fits this machine. A small compatible precut component or a fitting test section is a more conservative starting point. Review precut blanks versus cutting before committing to a manufacturing method. Follow material verification, extraction, eye-protection and supervised-operation requirements.
Compare against the actual neighbors
A new piece should be checked against the physical adjoining pieces, not only an on-screen assembly. Wood thickness, wear and any finishing can affect the fit. Never force a tight replacement until it splits an original edge; stop and revisit the geometry or manufacturing process.
Is the seed alone enough if I remember the puzzle size?
No. Tab choices, piece counts or generator changes can alter the result. Retain the exact exported geometry, with the seed as supporting information rather than the only recovery method.
Can I use a photograph of the empty space to replace a piece?
It may help identify the location, but perspective and scale make it a weak dimensional reference. Recover the original file whenever possible, then verify the resulting sample against the real puzzle.
