10 W diode settings: slate coaster, 6 mm

Quick answer

A 10 W diode cannot cut slate coaster at 6 mm, but it engraves it at around 100 percent power and 1200 mm/min. Slate is marked, never cut. The mark is the mineral surface fracturing, so results vary between individual coasters.

Community starting points, not manufacturer specifications. Optical power, lens, air assist and the stock itself all shift these. Test on offcuts of the same sheet before committing a real workpiece.

Read these as a starting point, not a specification

No machine maker publishes settings for third party stock, so every figure on this page is a community starting point gathered from tested profiles. Optical power varies between machines sold at the same rating, lens focal length changes the spot size, and air assist changes the result more than most people expect.

Plywood deserves a specific warning. It varies between sheets and even within one sheet, because the glue layers inside are not uniform, so a setting that cut cleanly yesterday may leave an uncut patch today. Always run a small test cut on an offcut from the same sheet before committing a real workpiece.

Why this machine cannot cut it

Slate is marked, never cut. The mark is the mineral surface fracturing, so results vary between individual coasters.

Publishing a number here would imply it works. It does not, and the honest answer is to move to a more capable machine class or pick a material and thickness this one suits.

Common questions

Can a 10 w diode cut slate coaster?

No. At 6 mm this is beyond what a 10 w diode can do, and slate is marked, never cut. The mark is the mineral surface fracturing, so results vary between individual coasters.. Use a more capable machine or choose a material this one suits.

What does percentage power mean here?

It is a percentage of the machine rated optical output, not its electrical draw or its marketing wattage. A machine advertised as 80 W might deliver 20 W of optical power from four diodes, and the percentage applies to that 20 W. Comparing settings between machines only works when you know the real optical figure for each.

Do I need air assist for this?

For cutting it is the single largest quality improvement available, because it clears smoke from the lens and debris from the kerf so each pass reaches fresh material. For engraving it matters less but still protects the optic and keeps power consistent through a long job. Settings published without air assist rarely transfer to a machine that has it, or the reverse.

Why did the same settings work last time and not today?

Material variation is the usual answer, especially in plywood where internal glue layers are uneven. Beyond that, a lens with smoke residue on it loses real power, and focus that has drifted by a fraction of a millimetre widens the spot enough to stop a marginal cut working. Clean the lens and re-check focus before changing the settings.
