While a Shapeoko is a great little machine, I would hesitate about calling it rigid, no disrespect. A cutter can exert quite a bit of force and it is possible that it's tweaking the Z axis enough to cause this. Things to rule out:

1) Is the slug/drop biting into the cutter and deflecting it into the part? Solution: tabs or pocket out the hole thing so there is no slug

2) Is the machine deflecting? Solution: Take the cut in multiple depths to reduce the pressure on the tool

3) Is the material deflecting? SolutionTake the cut in multiple depths to reduce the pressure on the tool, also consider vacuum holding, or double sided tape. Tbas can also be the solution here, as it does impart strength into the whole component
