How to Undercut 3D Chamfer?

[Skyler1440]

I'd like to machine an edge break chamfer in the machine. The problem is that this one is tricky to access. I was trying to make a toolpath to do this following this video:

I was able get a great scallop toolpath for the non-undercut chamfer, but have only gotten poor results trying to undercut this with the steep and shallow. Could anyone on here show me how it's done?

Thank you!

best toolpath for that is actually Flow(Preview)

Blend now supports undercuts too

Both of these need turned on in preferences:

I have attached your file with those examples.

You can use both of those for the top chamfer too rather than scallop.

My preference is the Flow toolpath now

Those toolpaths look great! Exactly what I need, thanks for your help 🙂
