You don't need a safety groove anyway with a conventional threading

I can see the index (In hal scope) when jogging the axis slowly. (By
slowly I mean 4RPM). Any faster, the index is not consistent.

Sounds like you need a new encoder.
I've seen encoders break like that - they get intermittent. I have no
idea why.

I looked at the configuration CHNC and it looks the same.
I followed andy's advice and found that the z-pulse is on pin 4. So I
connected pin 4, (Z Pulse) to an encoder component A phase (encoder.0).
Then set the encoder component to counter mode.
So now I have the encoder using the hostmot driv

Brian,
You might want to change the mode of the counter in the Mesa card to a
single channel counter (non quadrature) and hook the index pulse to that
channel. Then see if the Index pulse is counting reliably - 1 count
per rev.

You won't see it as a named pin, but all the function pins are also

It is wired up. I don't really know how to see if it is working.. I tried
connectimg it to a io port and create a latching circuit in classicladder to
see if it was sending a signal. I turned the encoder by hand and it would
latch the circuit every few turns. I may have had a timing issue...

First of all, thank you developers for EMC and thank you John Kasunich
for getting the m5i20 threading working. I loaded the pre 2.1.7 version
and built it on my pc, the threading worked first try, I only had to
change my old latch-index to index-enable and then tested it out, I now
have a lat

Of course, you have to have an encoder on the spindle.
And, you have to provide a way to feed this encoder information
back to the co

Right now, only a spindle with encoder and index pulse

Yes, it is possible. You need a spindle with encoder and index pulse
output. The sample configuration "nist-lathe" shows the necessary HAL
configuration when the encoder is connected to parport pins 11, 12, and
13.
The sample ngc file "threading.ngc" uses a bunch of G33 (spindle

Yes, there's a basic threading move (G33) and a threading cycle with
many features (G76).

Thanks, Isak.
