Wow! That's great. Very interesting. Thanks for the link. That said - that's a dual loop with two different encoders. That's not really the same dual loop when you have LinuxCNC and a Closed Loop Stepper/Servo Driver. _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
