Dave, there is no way around the .ctl file. That is what SWCAM uses. With that being said there are a few options.
1.) We have built posts on our website for free. https://hawkridgesys.com/products/cam/post-processors
2.) You can build your own using the UPG
3.) Get a customer post build specifically the way you want for a reasonable price.
If you would like a custom post created we offer that service. To get that conversation started follow the link above and select the button to "Request a custom post"
