Help! New Path Making Parts Wrong

Hello,

 

I had made the first part and all was good.  I went back into Fusion to adjust a chamfer and all of a sudden the path on a different operation changed.

 

I have attached the fusion file and a pdf.  The pdf shows what changed.  I can't figure out what happened.  I did go into the contour in question to change the feed.  Maybe I hit something else.  The operation in question is {T17}2D Contour3

 

Any ideas?

Is the issue that it's plunging into material? Turn on Stock Contours and select the profile of the square. This will scoot the toolpath out:

Seth,

 

The issue is the last pass, which is the blue line closest to the center of the part.  The one which is right against the wall  is the centerline of the 1/2 end mill.  Therefore it is making the part way to small

That's because you've got it set to "Control Compensation" and you need to input the radius of your tool into your control Offset page. For this reason, I prefer to use "Wear" compensation:
