Fusion 360 Milling post with G64 Pn

As promised in this thread , here is a copy of the Fusion 360 Post Processor, which I have modified as follows:

1) Added G64 to G Code preamble - can be enabled or disabled from the Fusion 360 Post Process dialogue as shown below.
2) Added the P value for G64 - this can also be modified from within the dialogue.
3) Added DEBUG command into tool comment during tool change so notification box pops up on the screen prompting for the tool to be used.

Let me know if this is useful and if you have any comments. In the thread mentioned above, it was suggested that a different P value would be useful for roughing/adaptive moves, which makes sense, however this is more challenging to code - particularly as I'm not a developer - it took me a while to work out what's going on in the post to get this much done!

All modified or added lines have been commented with //Spangled - search for these to check what I've done.

As usual, you test this file at your risk - it's not my fault if your machine crashes or your house catches fire etc. Check the output before running it on a physical machine!

This is excellent, Spangled. I'm currently working off of your post and trying to add to it so that any operations with an explicitly specified smoothing factor will add a G64 with the operations "smoothingFilterTolerance" variable as the P value.
That'd be a perfect setup, overall G64 P0.010 or so for roughing (in Inches) so fast roughing doesn't get too crazy, and then a per-operation specific G64 P0.00n to dial in where precise motion is needed.

BTW I have verified that your post works in HSMWorks as well.

Good stuff Marty - I must admit that I was in a quandy as to what name to use for the variable - whatever seems most appropriate is fine with me.

If you have the time/ability to create the code to have separate P values for roughing and finishing moves then that would be awesome - perhaps adding in the naive CAM detector - Q - option as well would be good for the roughing moves?

I may also submit this on the Autodesk Fusion360 post processor request board - it would be good to get this officially supported and anything that improves support for LinuxCNC can only be agood thing from my point of view.

Are there any other LinuxCNC features which haven't been implemented in this post that anyone has noticed?
