I'm milling a 14mm-dia wisher and I need to flat down the top surface of 1 mm.
Again, I've encountered the usual drawback of the Path WB when milling circular shapes/pockets: apparently there is not an efficient way for doing that.
Spiral pattern
It produces a strange path with a lot of stop-and-go and a lot of unnecessary travel (very inefficient -see below).
Zig-Zag pattern
Fascinating and with a lot of options. Unfortunately it has again a lot of stop-and-go (again very inefficient)
Offset pattern
Again massive and unnecessary travels. I also cannot reduce the number of passes (see the second image below)
On the other hand, I have an old, ridiculous, toy-like cnc-program that produces a very efficient spiral path when milling circular shapes. The milling bit never raise up during the milling of a layer.
When a layer is terminated it simply raise up the bit, return back to center and start a new spiral for the new layer. Simple and efficient.

There is no way to get something like that in the Path workbench? Maybe a special operation just for circular shapes could be added in the tool palette?
P.S.
About the spiral pattern: please note that I get always a wrong milling operation, i.e. some material stays not cut no matter how muche time I play with parameters.
