The output of the encoder-ratio component is a float value indicating the angular offset between the slave and the master. The assumption is that a PID loop would be used to control the slave and drive that offset to zero. You could add an intentional offset to the encoder-ratio output before the PID. The intentional offset could vary as the hob moves across the gear face to make helical gears, or have small steps added/subtracted to shave the leading or trailing face of the teeth. -- John Kasunich jmkasun...@fastmail.fm ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
