You won't notice much loss of resolution in that example (loss still occurs). But, let's say you put that same 20 x20 STL on an area 36 x 36. You will definitely be able to see the loss of quality. The bigger you go beyond the actual job size, the more resolution loss you will notice. Again, the PDF explains this very clearly and in detail. the video touches on it and shows an example in the presentation. The video is the "shorthand" version of the resolution vs job layout size. You'll get the complete explanation in the PDF. And, it's not a defect or "special" issue with Aspire...all the major pixel-based CAM software is the same. If you have a job with only vector cuts, resolution is not a concern in any case. It's only raster models, which as you may know, an STL model is instantly converted to a pixel-based model once imported into a pixel-based CAM software.
