Here's the hack-job I did to my Tormach Fusion 360 post to support G64 values as a parameter. Hopefully this setting will get baked into a future factory post and maybe in a nicer manner. Use at your own risk, bla, bla....

Edit the Tormach.cps file.

At the end of 'User Defined Properties', immediately after the number in reversingHeadFeed and before the //, around line 64, add a comma.
Insert a new line just after that one, before the } and make it look like this:

Drop down a few lines and add a description. Also add a comma at the end of the previous line

Search down for (64). Remove the gFormat.format(64) to make it look like so, adding the other highlighted lines.as well.

Save the post with a different name.

When you go to post some code in F360, pick your newly saved post and you should have an setting called G64 Tolerance that you can change as desired.
