Has anyone etched or engraved slate tiles? I am trying to do a project using slate tiles (400 x 400 x 12mm) for kids to draw on, and I want to put a logo up in the corner. We 950 x 600 100watt machine, and trying to get a handle on what settings I should start with.
Tnx

If you use the little search tool in the upper right hand corner you will find GOBS of examples…

Treat it like any other material and do some tests, but generally keep the power low or the engrave tends to get a yellowish tint.
On my 50 watt machine I use 8000mm/min @40% power (8mA).
It is usually recommended to coat the slate before engraving either with polyurethane (interior) or a very light oil like 3 in 1 for exterior signs. This gives the engraving a bit more contrast to the surrounding slate.
Hope that helps,
David
