What does "Error: Cutengagelimoptstepover < 2 * cuspheightrad" mean as an error for adaptive clearing?
I am trying to do adaptive clearing for the first time and would like to machine some GT2 profile (see attached file if it helps). To do this I will be using a tapered endmill with a very fine point. It has a 1mm ball nose tip and this is tapered (at least that is what I told Fusion I have so far).
I am getting this error currently:
The error is (I typed these into google and didn't find anyone getting this):
"Error: Cutengagelimoptstepover < 2 * cuspheightrad"
I looked into what cusp height might be and found something, but I am not clear on how to adjust the cusp height:
https://help.autodesk.com/view/fusion360/ENU/?guid=MFG-CUSP-HEIGHT-OVERVIEW
It says " Using the Cusp Height parameter, you can help ensure a uniform surface finish across the part by using the Cusp Height to automatically determine the stepdown and stepover values each time you use a different tool for an operation." however I do not know the location of this parameter.
Cutengagelimoptstepover is the other parameter -- this looks like "cut engagement limit for optimal stepover"?
Here are some of my current settings. Again I am just doing this for the first time and have not tried cutting in these conditions. If there is something very obvious please let me know.

I was able to find something called "optimal load" and reduce this from 0.2 to 0.1. That got rid of the error message, but I still don't know where the cusp parameter is or exactly understand what the error is about.
I did initially put "optimal load" to 1mm and it warned me that it needs to be less than the cutter diameter (makes sense, and as a tiny tipped tapered ball endmill as I specified it thinks it's even smaller than 1mm).
