Laser safety boundary

Software can improve preparation and evidence. It cannot certify a material, setting, enclosure, ventilation system, interlock, operator, or job as safe.

Unknown material means do not laser it. Verify composition and your local machine/shop policy before creating settings or output.

Website

The public site prepares, simulates, preflights, and exports. It never connects to or controls a physical laser.

Settings

A power percentage observed on one source, lens, controller scale, focus, material batch, air-assist state, and extraction setup does not transfer automatically to another.

Generated output

Supported G-code must remain laser-off outside explicit operations, end in a verified off state, remain inside the declared field, and state its unit and origin assumptions.

Emergency control

A software stop is not a physical emergency stop. Supervision, fire response, ventilation, enclosure, and machine-specific controls remain the operator's responsibility.
