The video shows him going to a depth of 0.1 mm - is that the secret ? - lots of sweeps at very shallow depths ??


I'm still very new to all this stuff - being able to cut brass and aluminum would be a definite plus. All advice gratefully received
Well without knowing your machine it's difficult to say how it will handle cutting brass, but if you chose the right stuff and take it easy on DOC then can't see why you shouldn't be able to engrave or cut brass without any troubles. You want something like CZ120 which is a free-machining brass and a nice carbide engraving bit.

Also if you are not engraving deep then look at using a diamond drag bits. This doesn't apply many cutting forces on the machine and doesn't require a perfectly flat bed or material surface as the spring-loaded tool adjusts to suit. If your planning on engraving without spring-loaded tool then make sure your bed is sufaced perfectly flat.
