Hi @james.welchBRK49
If you have not had any luck finding a post processor for your machine, you may want to look on the Autodesk Services Marketplace. This site will provide you all of the authorized Autodesk resellers that specialize in these services...including SolidCAD here in Canada. You can look through the list of resellers to find one in your region.
If you are interested, we can provide you a quote to get you a post built to your criteria. We have a team dedicated to supporting our FeatureCAM customers. We normally work with Canadian customers, but we have done this type of work for US companies as well that are not working with an Autodesk reseller.
You can email us at ams.support@solidCAD.ca if you'd like one of our sales reps to quote you on this work.
Thanks,
Christopher Marion
