I've simplified the project as far as I can to illustrate the problem. It consists of a 30mm pocket cut from a larger block.
I expect a straight path down the center of the cut. A 30mm tool does not generate any g-code.
However, a 29.999999999mm tool generates the expected path shown here:
Any idea what am I overlooking?
Very similar to the error in https://forum.freecadweb.org/viewtopic.php?f=15&t=25278, I get the following g code when the tool width matches the pocket width.
