Fusion 360 files start and immediately stop

Suddenly having problems with toolpaths from Fusion 360 (OpenSbp post). I have had them successfully working for awhile, but now all toolpaths start the router, stop it, then Fabmo thinks the job is done, then the machine moves to what looks like the starting point of the cut and stops. Tried this with just a circle (below), with previously working toolpaths, and new ones and all appear to be broken.

I can get VCarve toolpaths to work, but need Fusion 360. I turned the logging level up, but can't tell where this is can be read... Please help!

Ok, did a software update and things are working again. Not a very secure feeling not knowing what was wrong - hate to think that some mornings I could wake up and none of my files would work!

The only strange thing I can see is the C7 command at the beginning of the file. That is the command to turn off the spindle. However it is followed by the "spindle on" C6 command.
Depending on your software version of FabMo it may have had an issue with one of the other commands in the header. Updating is always the way to go though--as we have caught bugs in the past with different CAM posts and patched FabMo to deal with them.
