Fusion360 Post to LinuxCNC Error

I've been slowly getting a homebuilt CNC router up and running and keep running into an error when opening my programs in LinuxCNC. The error states "radius to end of arc differs from radius to beginning". I've searched the interwebs and I've seen recommendations for reducing pass tolerance (greatly increases tool path generation time tunnel rush ) and switching from a helix to plunge when lowering the bit into the work piece. These help for some programs but not all. Does anyone else have an issue like this? Thank
