Seems like svg vs ai/cdr. In an ideal world you wouldn’t need ai file support and you would code to a single, open standard. In reality, most graphics programs support all three (and several others) for maximum toolchain integration.
For anyone that’s been in the shopbot world at all, they probably own copies of Vetrix software that are tied to shopbot file formats. MakerCAM isn’t even in the ballpark if you are used to using something like VCarve, and for many Fusion360 is a bridge too far. So they are faced with a decision to spend hundreds on a program they already have, or spending time learning entirely new products. Either way, the Maslow gets more expensive as a result.
