Hi Dave,
RTFM, you don't need it
PZOUT+ Encoder Z phase differential positive output
PZOUT- Encoder Z phase differential negative output
The built in index pulse form the encoder is already available as an output, pins 42 and 43 of CN1. You are just making work for yourself, the manufacturer is
way ahead of you.
Secondly note that the A and B channels of the encoder are 2500 pulses per rev, when they are combined as a quadrature signal they give four times that as
encoder count or resolution. 10,000 count encoders like this are pretty much the norm for incremental encoders on current production models.
10,000 count encoder will give you potentially 2.16 arc minute resolution, surely that enuf even for an Aussie.
Last thing is that Mach ASSUMES constant spindle speed when threading. Your spindle could conceivably provide variance information in between each
revolution buy Mach can't do anything with anyway.
