I'm surprised that people don't use kinematics to remove the residual alignment errors that can't be mechanically removed. Of course, you can't remove tool orientation errors this way. If the z-axis is a few milliradians "off" the tool will also be "off" but kinematics can compensate for the X, Y error associated with variable Z movement.
That said, I can't measure this kind of low-level stuff so I don't worry about it. You should be able to lead the Z- column over at 45 degrees and still hit X, Y point spot on. (it would work only for a spherical tool) On Sun, Dec 12, 2021 at 9:47 AM Gene Heskett <ghesk...@shentel.net> wrote: > On Sun, 12 Dec, 2021 at 12:13 PM, Chris Albertson < > albertson.ch...@gmail.com> wrote: > > > To: enhanced machine controller (emc) > Would "non-trivial kinematics" correct for non-square mechanical axis?
