Focal distance is critical on galvo heads — set exact height with the focus ruler before every job.

How to dial it in
The chip row above is the middle of the known-good window for a fiber / mopa 20–60w on anodized aluminum. It is a starting point, not a guarantee: two fiber machines with the same sticker can want different numbers once lens condition, air pressure, and material batch get involved.
Run the bracketed grid on the exact scrap you plan to sell. Watch for even tone without scorching or grain flare — drop power before you drop speed. Then log the winning cell so the next batch starts from your machine’s truth, not a forum thread’s.
Safety first, every time
Ventilate, keep a fire blanket or extinguisher within reach, and never leave the laser running unattended. If you are ever unsure a material is safe, it isn’t — chlorinated plastics like PVC and vinyl release chlorine gas and never belong on the bed. See the never-laser list.
Questions on this chart
What power and speed for anodized aluminum on a fiber 30w?
Start around 35% power and 2000 mm/s. Then run a test grid from 20–50% × 1300–2800 mm/s on scrap and circle the sweet spot — your lens, air, and material batch shift the window.
Do these Fiber 30W settings transfer to other machines?
They transfer within the class — any honest 20–60W pulsed fiber machine is a good starting match. Across classes they do not: power percentages mean different energies on different sources, which is exactly why the library is class-based.
Why does the chart say “starting points only”?
Starting points only — every tube/diode, lens, and material batch differs. Always run a test grid on scrap. Ventilate; never leave a laser unattended.
