Which Post Processor would be needed for CAM

We will be using the Dominator Pro with Onshape. Onshape will be providing us with CAM Studio to do our CAM work. With that process, we will need to tell it what Post Processor to use. So which one should we either select, or ask Onshape to add to their suite?

I’m not familiar with that CAD software. Is there a Masso selection, because that would be the one you would use?

While I am still digging into this question….

I found this current list of supported Post Processors in Onshape CAM Studio:

Do any of these look valid for use with the Masso controller?

Note that customizations is fully supported.

Stepcraft uccnc looks like it could be close.
Grbl is the only other one I’ve had hands on experience with but masso doesn’t use grbl
