Reply to dmthompson - if it shows up in the preview, it's going to show up in the carving. Aspire's preview is very much "what you see is what you get" and is surprisingly accurate. To me, that's one of the best things about the Vectric products - it's easy to see and fix problems before you cut.
The issue isn't screen resolution, it's modeling resolution, which is a different thing. The internal data model for Aspire is pixel based. The number of pixels in a model (regardless of size) is determined by modeling resolution in the Job Setup panel. Your screen resolution has nothing to do with the number of pixels in your model. Please see this Vectric faq: http://support.vectric.com/aspire-quest ... look-rough
. There used to be a detailed description of the Aspire data model somewhere on the Vectric site, but I can't seem to locate it.
Vectric's standard answer to this issue is to increase modeling resolution, which makes the pixels smaller and helps make the jagginess less noticeable, but doesn't eliminate it. Nothing wrong with this, but if you want to go further, then the strategies discussed already can be used (i.e., adding draft, making sure you have a zero plane, and using 2d toolpaths [which are not pixel-based] to shave off the jaggies)
