Still using v-carve pro, haven't had the need to upgrade to Aspire, but it's done everything we've ever wanted it to do. I've seen a lot of work out of aspire and it's very powerful. I've programmed CNC machines since 1986, from manually writing g-code to using very expensive software that only ran on Unix workstations. When I saw what you could do with Vectric's software, I was impressed, when I saw the price, I was shocked. To get that much power for that amount of money is a bargain. We had software we paid $30,000 for that wouldn't do a fraction of that stuff.
It's really come a long long way and it's all so inexpensive, and it's very easy to use, very user friendly.
