About Plastic Settings for the Epilog FiberMark 30W

The Epilog FiberMark 30W cuts Plastic cleanly at 1100 mm/s with 65% power. Always test on a scrap piece first — every machine is slightly different, and variables like tube age, lens condition, and material batch can shift results.

For Plastic, the key variables to dial in are speed and power. If the laser isn't cutting through cleanly, slow down or add a pass before pushing power higher — excessive power causes charring and wider kerfs. Air assist is highly recommended for wood and organic materials to clear smoke and protect the lens.

Once you find settings that work, save them in Laser Lab to build your personal settings library. The AI predictor uses your calibrated results to suggest starting points for new materials automatically — so the more you log, the smarter it gets.

Frequently Asked Questions

What speed and power for Plastic on the Epilog FiberMark 30W?↓

For cutting Plastic on the Epilog FiberMark 30W, start at 1100 mm/s speed and 65% power. These are manufacturer-verified starting points — always test on scrap first.

Do I need air assist for Plastic on the Epilog FiberMark 30W?↓

Air assist is strongly recommended when cutting Plastic. It clears smoke from the cut path, reduces charring, and helps protect your laser lens.

How many passes to cut through Plastic on the Epilog FiberMark 30W?↓

The manufacturer recommends 1 pass to cut through Plastic at 1100 mm/s and 65% power. If the cut isn't clean, try reducing speed slightly before adding more passes.

Why isn't my Epilog FiberMark 30W cutting through Plastic?↓

Incomplete cuts are usually caused by incorrect power, speed, or focus distance. If edges are charred, try increasing speed or reducing power. If the laser isn't cutting through, reduce speed or increase power — or add an extra pass. Also verify your focal distance is correct for the material thickness and that your lens is clean.
