Internally it compares the feedback and command voltages. If both signals are generated by LinuxCNC from the same encoder in the same thread then you are using two analogue channels to provide a voltage difference when you could use one, at least in theory. As this is a lathe and you have 4 channels available the inefficiency probably doesn't matter. ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
