Trial-shot parameter — small batch onlyRecommended for production

Note: parameters marked in red are trial-shot values. Actual results vary significantly with material, gas and machine condition — they suit small-batch production only and are not recommended for high-volume runs. A higher-power laser is advised for series production.

Frequently asked questions

Are the laser cutting parameters free to view?

Yes. Every parameter table can be read without an account and without payment — all of it, no tiers. What is paid is not content: it is me looking at your specific machine.

Which laser cutting machines are covered?

The library holds 21 machine configurations and 1,668 parameter rows, covering carbon steel, stainless steel, aluminum, brass and copper. Each configuration page states its optics setup.
