I'm getting a rotary axis dialed in. I'm using VCarve to generate a rotary wrap toolpath. It seems like its not raising the cutter to clear the part when transiting to a new section of the cut. It appears fine in the Vcarve preview with the rotary moves happening at safe Z.
The toolpath preview in Mach appears to have these moves occuring with the cutter close to the center.

Also, the rotary speed is very slow. I understand this is due to inverse time but I can't find clear directions on how to adjust for it.

Thanks in advance!

I have experienced the same non-retract problem as well.  Using a diamond drag and everything worked but had one place as it traversed it  did not retract.  Will be following the response on this.  Sorry I couldn't help.
Didn't see any post on Vectric forum from you.

I think I found a work-around. In Vcarve I put a vector boundary around the "unwrapped" part with a negative offset equal or greater than the bit diameter. I think this kept the toolpath from going off the map. When I was having gouging problems the vcarve simulation showed the bit carving a tiny bit on the left of the part and then it picked up carving on the right. When I added the boundary offset it completed the entire area without lifting. The toolpath created with the boundary offset cut fine.

I still think there is a setting in Vcarve or Mach 4 that would prevent this entirely.
