True, though there is something to be said for having a dummy axis just so that the LinuxCNC GUI will display the encoder position. You don't need a stepgen, just set up the system as normal but leave joint.N.motor-pos-cmd unconnected. Connect motor-pos-fb to the encoder counter. Then set the following error limits to several miles, and you should get an onscreen readout of the probe position. (set the gui to actual, not commanded..) I am not sure what the built-in parameters such as #<_Z> show in this situation. I would suspect that it is commanded position but it's not hard to find out. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
