Thanks Hood ,

I'll give this a try.

Hood,

Until I hear back from Vista...

Could you give me a sketch on how to hook up the Optek OPB916B sensor and the 220 Ohm limiting resistor for the LED?
I need to know where to connect all the 5 wires, and associated parts.
I'm "NOT" an electronics guy... so please hold my hand with the sketch you might provide.
I'm sure others like me will be grateful.

Good plan Hood. I already got a response from Lee (Vista) and he's looking into it.

Hood,

This is a bit of a shot in the dark for me, but I wonder what you think of this idea. I've got 2 of these speed sensors. One doesn't work (I think the USB connector is a problem). I'm thinking of cutting the USB end off and try to set up this sensor to the standard pin configuration required for Mach3 threading. I'm quite sure that it is a USB 2.0 plug which only has 4 wires.

1 VCC Red +5 VDC
2 D- White Data -
3 D+ Green Data +
4 GND Black Ground

Can you give me your thoughts on where I should connect the 4 wires? (I think you already solved the 5v wire with pin 26

I'm willing to try even if it does not work.

Hood,

I've been watching your posts for a long time and I need to say that it's great to have someone with your knowledge taking time out for the ones that struggle (like myself). You have put me on the right track to get my problem fixed.

A special thanks to you!

Ray

Hood,

Thanks very much for your feedback. I am contacting Vista and hope that they can provide a modified version of this sensor so it could easily be hooked up to the index port and pin. Do you think I would need an external power supply or would the pin provide the power needed.

Hood,

So what is my alternative? What simple alternative do I need to get it working?

It's the one from Vista CNC.

Hood,

When I turn on the Use Spindle Feedback in Sync Mode the green light stay on continuously, and the tool refuses to move from the thread start position (obviously waiting for a signal). I'm using a USB RPM sensor which Mach3 reads... what port and pin would I enable for that?

Thanks,
Ray
