What the Preview Confirms — and What It Cannot
The Preview window simulates which shapes fire, in what order, and how the head travels between them. It does not model warped stock, hold-down hardware, air delivery, or material density. Treating a clean simulation as proof of a clean run is the gap this article closes.

Why a Preview Is a Planning Tool, Not a Result
A preview renders the planned sequence faithfully: layer order, inner-versus-outer priorities, and non-firing travel moves. Approving a job on that evidence alone assumes the drawing is the whole story.
The simulator has no model of the sheet on the bed, the clamps holding it, the condition of the optics, or the assist gas that will actually flow. Reviewing the preview answers “will the machine visit these shapes in this order?” — it cannot answer “will the part come out finished?”
- Use the preview to confirm firing order and direction only — treat every physical variable as still open.
- Cross-check the simulated travel moves against where clamps and fixtures actually sit on the bed.
- Close the loop with a physical framing pass and a material state check before enabling beam output.
Operational Key Takeaways
Preview Review Best Practices
A green preview is the start of verification, not the end. Build these habits around every simulated run.
Never treat a clean preview as approval to skip the physical framing pass.
Re-run Preview after any layer, grouping, or priority change — the order you checked may no longer be the order that will run.
Verify workpiece flatness, clamping, and optics on the machine; the simulation assumes none of them.
