About Iron Settings for the Sculpfun iCube Ultra IR 1.2W

The Sculpfun iCube Ultra IR 1.2W cuts Iron cleanly at 2.5 mm/s with 95% 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 Iron, 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 Iron on the Sculpfun iCube Ultra IR 1.2W?↓

For cutting Iron on the Sculpfun iCube Ultra IR 1.2W, start at 2.5 mm/s speed and 95% power. These are manufacturer-verified starting points — always test on scrap first.

Do I need air assist for Iron on the Sculpfun iCube Ultra IR 1.2W?↓

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

How many passes to cut through Iron on the Sculpfun iCube Ultra IR 1.2W?↓

The manufacturer recommends 1 pass to cut through Iron at 2.5 mm/s and 95% power. If the cut isn't clean, try reducing speed slightly before adding more passes.

Why isn't my Sculpfun iCube Ultra IR 1.2W cutting through Iron?↓

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.
