If you want to do rigid tapping then you need a full set of index and two quadrature lines, otherwise EMC can't tell which direction the spindle is turning. In index-only or index+pulses the encoder only ever counts up. It might be possible to use only the two quadrature channels without an index, I don't know if EMC2 supports that. You would have to be very sure of not missing a pulse though. -- atp ------------------------------------------------------------------------------ Come build with us!
