You need 3 pins for rigid tapping... A,B and index.

Well durn it, that means the encoder wheel I designed wont work.
No biggie, I've got a couple of BEI industrial encoders that should do the trick.. couple of MX pulleys and I should be back on track.
Might still make the wheel though, could using something to play with color anodize....

Very late with this info, but it would have been fine.
You can add a B-phase with a second sensor N +/- 0.25 teeth offset round the wheel, and use a deeper slot for index.

You can see the one I made for my (nasty, Chinese) mill at 25 seconds into this video

Sorry, that was meant to be a link to 25 seconds in, and not a whole embedded video. (because the video, other than the encoder, has no relevance at all to this thread).
I don't see any way to delete or edit my post, though.

Never too late Andy.
Ya, I realized I could have merely added another sensor or two and basically made the quad and index pulse - but too late into adapting the encoder I have. Been having some frustration with it though and am a little concerned about the 1000 cpr so, I might fall back to my first idea.

can you tell me about your electronics? are you using pathpilot?

I was using normal LinuxCNC (and I still am) and the interface is a Mesa 7i43 card in the video. 1000cpr should be no problem at all with the Mesa card encoder counters, if you can find an extra one.
Does the HAL file specifically disable encoders? Look at the "loadrt hm2_pci" line to see.

I ...Look at the "loadrt hm2_pci" line to see.

It says: loadrt hm2_pci config=" num_encoders=0 num_pwmgens=1 num_3pwmgens=0 num_stepgens=5 "

I have a 5i25 with the first port connected to a 7i76 and the second port connected to a C10 BOB. havnt done anything with them yet since 1. I'm still wrapping up the encoder install and 2. I have no idea what I am doing when it comes to linux/hal/...etc.. yet.

Just delete the "num_encoders=0" part and see if any appear :-)

[SoCalPlaneDoc]

Well that was interesting...

deleting the num_encoders=0 yielded an error during pathpilot startup: "Machine control software expierienced an error. Install a software update"
changing the num_encoders to equal 1 threw the same error. Changing it back to zero, pathpilot started up fine.

Finished encoder install.. moving on to wiring....
