Here is the F360 Machine file for the SnapMaker A350. Bear in mind this doesn’t actually properly map the movements to the linear rails. It does however move the head module and bed into the right positions within the defined work zone of the machine.
As I realized late this doesn’t really matter because the post processor does not support machine simulation. From what I tested it seems like most other common processors like GRBL also don’t support machine simulation. So this could just be a proprietary feature that the Fusion team codes for the machines that it would prefer you to use which are almost entirely over $10,000.
Anyways I was surprised that someone had not provided these files yet on this forum. It seems like a pre-made machine file with a fully accurate config file should be available to download on the forum with the post processor. So for posterity I am posting it here with links to all of the resources I used to make it. Beyond the simulation file it would be good if SnapMaker provided an official configuration file for Fusion 360 or alternatively if someone who has a better understanding of CNC motion systems could provide their own for the SM 2.0 A350 that has all sections in the kinematics fully filled out.

Notes
I am not an engineer. I also made this model in a stubborn fervor last night so things will need to be adjusted and measurements will need to be checked to verify that this is an accurate model with an accurate movement mapping. The Kinemetics section while broadly filled out needs additional information because I was unsure about some of finer specifications without doing more research.
Also something to note is the table mounting hole Diameter could be off by about +/-1.5mm didn’t have my machine near me when I adjust them but they should be in the right position.
