Shapeoko 3 post processor

Fusion 360 indicates shapeoko3 post processor does not support simulations.

Does anyone know of a post processor for shapeoko3 that does support simulations?

Are you sure you need machine simulation ? It’s a semi-pointless feature in Fusion360 which allows to see a 3D model of the machine itself moving as the cut progresses. If this is what you are interested in, see this thread for all details on how to make it work:

But I believe you may be referring to toolpath simulation that previews the cut ? and that works if you just ignore that warning message.
