Hi there, I have had previous experience using a vinyl cutter in the past and was looking at getting into some work with a laser engraver.

I was wondering when using a co2 engraver with corel or adobe or whatever software is supplied. How does it work when cutting on an uneven surface.

Ideally a person probably would like NOT to do this however I'm sure it happens time time....how does the machine compensate for that?

Do you have to set it up in the software? or does the machine auto focus with its lense? Does that cause the image/pattern to be distorted? Just wondering how that works?

Thanks!

Depend from what you mean UNEVEN. If it's 1-2 mm - you don't need compensation at all, as laser focus allowed cut/engrave slightly out of focus. If you talk about bigger change - up to 5 mm - possible solution is multi pass cutting with different focusing ofr each pass.

Ok I get what your saying....what about say like a half sphere..or anything with some sort of arc...I guess ideally a person would have a rotary attachment for such a thing?

I guess an extreme example would be lets say the inside of a stainless dog dish (bowl) even a shape of such flipped upside down

General: of course if you have some kind of arc - you need rotary.

Dog dish - I afraid you need NdYag laser to engrave on it.

Ok! Thanks for the response...I was thinking there might be some trickery with software to be performed but if it is a limitation of the hardware then I can accept that from a co2 basic machine

Thanks!
