The Job Preview feature simulates the real machining process of the laser engraver in real time. It allows you to visually inspect the laser head’s movement paths, processing order, and overall operation effect — helping you evaluate processing efficiency and feasibility before the actual run.
¶ 1. Interface Overview
¶ 1.1 Preview Window
- Idle Path: The red lines represent the laser head’s idle movements — the non-working transitions from the start point to the engraving area, or between scan lines.
- Engraving Path: The black dots indicate the actual burn trajectory where the laser is active and processing the material.
¶ 1.2 Interface Controls
- Play Button: Start or pause the preview playback.
- Progress Bar: Displays the current playback progress. You can drag it to view any specific moment in the simulation.
- Playback Speed Selector: Adjust playback speed across multiple levels — 0.1x, 0.2x, 0.5x, 1x, 2x, 4x, 8x, or 16x.
- Idle Path Toggle: Show or hide the laser head’s idle trajectories.
- Zoom Control: Adjust the display scale (10%–9999%). You can also zoom with the mouse wheel or drag to move the view and inspect details.
- Reset View: Instantly restore the default zoom level and view position.
¶ 2. Usage Tips
- Use Job Preview before actual engraving to verify path directions, processing order, and estimated duration — this helps assess if the task time is optimal.
- If the laser head shows unusual movement or excessive idle travel, adjust the path order or refine the design in your editing software.
- When issues like incomplete burns, shallow engraving, or broken lines occur, drag the progress bar to the problem area in Job Preview to analyze the laser path animation and identify potential causes.
