Preview looks wrong

You see

You open Preview and it shows:

• The wrong order of operations.
• Missing layers / objects.
• Extra geometry not on your canvas.
• An unexpected path direction.

What is happening

Preview is the result of running the planner. If preview looks wrong, the planner has produced something different from what you intended.

Fix

If a layer is missing from preview

• Verify the layer's Output is enabled in the Layers panel. Processing entries with Output off do not appear in Preview.
• Verify the layer's processing entries are enabled and appropriate for the artwork.
• Verify the layer has objects assigned and that those objects are visible.

If preview shows extra geometry

• Tool layers do not output. Check the actual layer type and processing entries. The former Include tool layers in job bounds preference has been removed.
• Virtual arrays sometimes expand more than expected if count was set wrong.

If the order is wrong

• Reorder layers using their tabs or the Layers panel controls.
• Layer order is the starting arrangement; optimization settings can change planned traversal.
• Check the Optimization Settings modal (Laser Control → Optimization...): the Order by option might be set in a way that reorders layers.

If preview is stale (does not match recent edits)

• The panel header may show Stale, refresh required. Click Refresh.

If the previous preview remains visible during generation

Wait for the Generating preview... state to clear before judging the result. A previous plan may remain visible while its replacement is being generated. Review the new result and any warnings, and resolve generation errors before running the job.

Verify it worked

• Preview matches what you expected.
• The actual job confirms, what preview showed is what the machine did.

Still stuck?

• Preview dialog reference.
• Cuts / Layers panel.
• Laser Control: Optimization settings.
• Post in the Facebook group with a project file demonstrating the issue.
