    For a 10 year old machine Kev that's tidy, nice bit of work at sizes that small.

    Much as I like Chinese lasers it's unlikely a DC tubed gantry machine will match that quality.

    You did what !

    Yes, that is the kind of proof I need about some of what I am giving up vs a better machine.

    Is that machine galvo or gantry?

    Gantry I'd bet, Galvos weren't in the public domain as much 10 years ago.

    cheers

    Galvos wont allow smaller engraving, if anything its the other way round, i will try some small letters on a fiber tomorrow, the small spot size due to the laser should allow me to beat anything posted thus fair. A gantry fibre would allowing even smaller marking as you can use a shorter focal length lens!

    As Dan pointed out is all becomes pointless as you need a microscope to see it after a while, but it will give you a comparison.
