Blend toolpath: Wavy stepover

Yea, Blend does weird stuff sometimes, which is why its still in preview(for as long as I have been using Fusion, like at least 5 years)

I had heard that it was maybe being worked on again by Autodesk but now sure.

It really is frustrating as its the perfect toolpath for that type of feature(In theory), I played around with all my usual tricks and couldn't get it to perform any better than what you had.

@seth.madore  any ideas if these rumors are true?

@a.laasW8M6T thanks for tagging me. YES, Blend is being worked on with a high priority. 

Regarding the waviness, you can turn on "Machine Undercuts" and then set the Boundary to "Tool Outside" and get this:

 It needs work, it's dropping a few linking moves...

Thanks Seth

Any idea why those settings would help? to me that's not at all intuitive for that geometry(there are no undercuts)

(I like to try and understand what's going on in the background of fusion that causes certain behaviors.)

Cheers

Different Kernels are activated. With it "on", it's using the old Kernel, when it's "off", it's using the new Kernel. Eventually, that will go away and it will be the new kernel in all instances. For now, the new Kernel does not support undercuts at all

OK interesting to know, BUT  I just went to look for a machine undercuts option in BLEND and cant see it anywhere, is this like an insider build option?

I did find it in compare and edit but its greyed out and set to yes

[seth.madore]

Yes, it's quite likely
