Got a datasheet from BEI on the encoder. 3=Quadrature with index 25=0.25" bore 127=127 pulse/rev 127 seems to be rather coarse, especially considering the stepper is 200 full steps/rev and is geared down via cogged belt. Apparently whomever specced out this mill wasn't looking for high precision on the Z axis. BEI no longer make an encoder this style with only 127 PPR. 500 is the minimum. ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
