Aspire won't run anything at all, it is not CAM software. Aspire creates tool paths, same with Artcam. I have both.
You can make a design in Aspire 3 to use with Mach 3 or most any other Post processor. But it does not run a machine in any way.
I don't see Sabre listed as post processor in Aspire 3. Which do you use and I will check if Aspire will create a tool path for it. Of course you can create a pure generic G-code file with Aspire, that may work.
