My lathe spindle originally had an Index pulse and 10 encoder pulses per revolution. From the problems discussed in

I thought it would be better if I generated more than 10 pulses per spindle revolution.

I built a ring to fit on my lathe pulley with 180 teeth. I picked this size because it had the most teeth that I though I could machine. They were about 1/16" width and depth. I found that the proximity probe I was using could not detect these small teeth. I replaced it with a Hall Effect Sensor =11.0ptS38J-22ADSO-5KJA5 from Standex Electronics. Here's the installation:
 

Here's what the output looks like at 400 RPM on my oscilloscope:
 

This is about 24V. The frequency of the signal is about 6 cycles in 5 mS, or 1,200 Hz. Expected signal is 180 pulses * 400 RPM / 60  = 1,200 Hz. So far, so good.

The signal goes into a breakout board with optoisolators. I can see the signal on the input and output side of the optos, so I know it's going into the circuit OK. I don't see any missed pulses on the oscilloscope. The breakout board feeds a Mesa 7i92.

When I pull up the encoder inputs in HalScope, I see:
 

Not good. I should see 180 pulses between the index pulses. I'm seeing about 10. Plus, one of the index pulses is missing.

I have a separate DRO that also displays the spindle RPM. If I compare it to the RPM shown on LinuxCNC, they match from 0-150 RPM, then for higher speeds LinuxCNC shows speeds lower than 150.  So if the lathe is at 500 RPM on the DRO, LinuxCNC shows about 60 RPM. Again, I can see on the oscilloscope that I'm getting all the pulses.

Here is my .INI and .HAL files. Any ideas?
 

isn't 'cia402.n.controlword' an output pin? (you can't setp output pins)

Hahaha
I used to get the "I'm a hacker and have hacked all your devices and have videos of you watching rude videos and doing rude things"
My reply was "all still images and videos of myself are copyrighted. I will have my people visit you to discuss your upcoming self deletion. As we are reasonable people we will not expose your friends and family members to the videos you have collected of random people doing things"

These always came to an old Hotmail account I've had pre 2000, and look at every 2 months or so.
Seriously, I've seen every scam known to man come through that.
