To: enhanced machine controller (emc) 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) If it was moveable Chris, but its not, the column is fixed, but the head can be rotated 90 degrees either way and I have several times. That works quite well. But there is no detent so it must be re-trammed when turning it vertical again. I've not yet had a chance to look at non-trivial kinematics. Now I have and am amazed at the lack of details as to how to configure for an out of square machine. No clues at all. -- Thanks Chris Cheers, Gene _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net<mailto:Emc-users@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/emc-users . _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
