prototrak mx2 cam software?

Hi all, forgive me if I've posted in the wrong place. I have been using my xyz1500 with prototrak mx2 controls for well over 2 years now and have found it to be such an easy machine to use. How ever, as ia starting to make more complicated shapes now, it gets more and more complicated to use and time consuming.

I was wondering if anyone have some suggestion of any good,cheap 2d can software that would work with a prototrak mx2?
I don't want to spend too much as I will only be using the software for hobby use only.

Any help would be much appreciated.
