Hi I recently acquired a 6' x 13' cnc router table built by a local guy. I plan to use it for cutting out aluminum boat parts. The guy who built it suggested vectric Aspire as a program for creating my tool paths from my dxf boat cut files. I've done some playing around in it and I do like that it's fairly simple to use but I've run into a problem that I'm really surprised the program can't handle. So I want to cut out the outline of say a cross frame on a boat, this would be like a vee shaped frame, but it would have some notches for longitudinal frames that it would slide into, so there are some inside corners on the object. In Aspire I can only choose 1 tool for profile cut. So I could choose a 1/8 end mill to get into the inside corners but this would be way too slow to cut the entire frame out. I want to use a big bit, maybe 5/16 to cut the majority of the frame, and then switch to a smaller bit to clear out the corners and notches that the big bit can't get into. I could make a separate tool path for a 1/8 bit but then it's still running the bit along the entire path that the larger bit has already cut. Is there some simple solution for this? Or can someone recommend a different program then Aspire for doing this that has a simple interface. I also tried rhinocam but find it too complicated for what I want to accomplish. I'd also run into the same problem if I wanted to cut profile of some text and / or logo's for say aluminum signs.
