Flow toolpath with 4th axis

[the456]

I'm having trouble trying to post out a Flow toolpath while using a 4th axis.  I can't show the actual part for security reasons but I've replicated the problem here.  Machine is a VF3SS with pre-NGC paired with a HAAS 4th axis mounted inline with X axis.  Using the correct post and machine config but am getting this on posting: Error: Error: Direction is not supported for machine configuration.
Error at line: 1

Cannot for the life of me figure it out?  I've done wrapped 2D profiles with axis sub before but never anything like this.

Now using HSMWORKS with same path and setting up 4th axis sub it works but in that program it does not give a clean extension at the part boundary like the path in Fusion 360 is showing but it does post out good code using same post processor.

It is outputting A and B axis moves if you have a look at the toolpath from the side you can see it.

Have you tried the Rotary toolpath yet?

I tried rotary and while it works on the concentric test cone it does not quite work on my actual part.  I drew up another representation of my part, this time with a more accurate outside shape.  Any suggestions?

Actually, Rotary DOES yield a great result, if you play with the Heights a little bit. See attached file

I like posting photos directly, but that option is broken at the moment, unfortunately...

Are the Hight setting working fine for you Seth the playing I did the other day I had to take the hights from the stock using selection? otherwise, the planes were many inches away from the part.

[seth.madore]

It was working for me, at least in the simulation and programming. Didn't post the code though...

Thank you for the help.  I thought the heights would be taken from the model and never thought to play around with the tab values.  Works great!
