Based on a link @Bruce sent to me showing a clever way to do double-sided milling, I incorporated the feature into Kiri:Moto’s registration operation. Take a look at the video to see how it works. This is live now in the 2.6 development version.
That is clever! I presume the thickness of the steps corresponds to the diameter of the tool so you still have a tight fit after the flip?
The step size is somewhat orthogonal to the endmill size. Geometrically it works out to be a perfect fit (zero offset or overlap) if you flip it on either axis.
Is there a way to prevent flipping it on either axis? If, say, you only wanted it to ever be flipped on just one?
like a system preference that hides the Y axis option? the current geometry both allows flipping on either axis, but necessarily must allow this to work.
that would still allow flipping on either axis, but would be less secure when pressed back in place.
