we have used many encoders with index pulses and linuxcnc (mesa hardware) So far no issues. I have checked a few just to make sure - I set the index-enable true on the encoder and then turn the encoder. When it goes false - it has detected the index.
are these linear scales? usually those only have indexes at each end. sam On 7/19/2016 7:20 AM, Leonardo Marsaglia wrote: > Could it a disadvantage the use of a digital scope over an analog one?.
