Material Test Border: When to Cut the Grid Free
The Material Test border can be used as a separate cut around the test grid, useful when you want a portable labeled sample; it needs its own safe cut setting.
Material Test Presets: Repeat Tests Consistently
Presets reduce setup friction, but a preset is a test definition — not proof that the same result will occur on another laser or material batch.
Reducing Char: Speed, Power, Passes and Airflow
A darker edge can come from excessive heat dwell, poor air evacuation, incorrect focus or too many slow passes; power alone is not the only variable.
Cutting Preflight: Focus, Air, Frame, Preview and Test
Reliable cutting comes from a repeatable preflight: material identification, focus, air assist, clean optics, correct layer settings, Preview and Framing.
Kerf Offset: Compensate for Material Removed by the Cut
Measure real cut width and compensate fit-critical parts instead of scaling the entire design blindly.
Material Library: Build Reusable Settings Without Losing Machine Context
Store tested Cut Settings by material and operation, while keeping enough context to know which machine and thickness they actually belong to.
