No. The CRV is not a G-Code file, it’s a proprietary format that VCarve uses to keep all the information needed that shows up in the vectors, embedded bitmaps, toolpath & machine definitions. The NGC files are G-Code files that the Buildbotics controller’s embedded software can turn into physical movements of the machine.
I’d open a VCarve support ticket because it sounds like you’re doing everything right but the G-Code isn’t being created & stored in the NGC file.
