I suspect you connected them as MPGs, as that would be the most logical thing to do. I don’t think I want MPGs because the axis need to move during NC moves. Perhaps if I were more clear as to what the purpose is of this axis … I plan to use this axis with the linuxCNC probe features to automatically record the profile of a surface as the Y axis moves across that surface. The probe will have a roller on the end, which will be held in contact of the surface by gravity or a spring. At this point, I am trying to find the correct hook to feed the position/velocity from the encoder into the joint, as Gene suggested, to get rid of the following error. Do I even need the stepgen? Can I have a joint without a motor? Can I configure the joint to ignore the following error and still get good position feedback? _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
