Hi

After wasting a couple of days trying to learn post processor editing and getting nowhere - I'm hoping someone maybe able to support me

Does anyone have a Denford Novamill Fusion 360 post processor?

Fusion 360 offer a generic Denford post processor which is probably close enough but it has un-supported G codes which I would need to remove.

Couple of questions on post processors:
I'm a little confused - The Novamill does not support arcs, if I delete this function from the post processor, and the function is required to generate a toolpath, how does the generator know to select a different option?
What happens if I delete a G code that is mandatory to the generation of a toolpath?
I'm using Denford VR Milling V5 software to control machine, it will still run code which includes unsupported G codes (G18 and G43 for instance), I'm assuming it will throw up an error when it comes up against a compulsory code?

Thanks
Chris
