You might try Fusion 360, will replace both Enroute and Toolpath. It's free to small businesses and hobby users. They have a post processor for axyz, but I don't know if it's compatible with your boards, but can be modified to output what is needed.
The other option is to just do a full controls upgrade, there are a lot of options available, but I don't know how the cost would compare to just upgrading your boards from axyz.
