Um I haven't got it to work yet . Didn't spend much time . But what I did was enable fast encoders , pins 1 A , 2 B. but I didn't get it too work . Don't know how to tell Mach 3

As of now no all inputs are used , I currently have the A and B for mpg , one for limits , and one for an optical sensor for a home/ limit for the z . Do you think I could slide the a and b over to the pokeys or even the home and limit switch .

Ok I grounded the shielded cable and still have the same problems , it did however help a bit . I will try to get a scope to it to see clean signals to the pokeys .

Yes , I have tried inverting the signal in the pokeys plugin as well . I have however just remembered that I never grounded the shield for the cable in the control . I will try that and let you guys know . I might even put a scope to it to see if there is noise .

Thanks rich , however the debounce seems to have no effect on the pulse. Also I notice in diagnostics that the index is not pulsing at the same constant rate as the led on the optical sensor . Does this matter . It seems to be also erratic . I also have tried this on a pmdx 122 bob. It had the identical results.

Hi guys ,
My problem is my index is showing the rpm eradically. I call for s800 and it gives me anything from 150 to almost 1000 it stays somewhat steady at 350 .
I am using pokeys 56e for the input on 7 for index
The sensor is a Pmdx 170 slotted optical sensor
I have a 1100 ohm sensor from v+ to true . I check at input 7 with a multimeter and I am getting 5 volts when it pulses and zero when interrupted . Index debounce
 is at zero . My slotted disc is 4 inch and my slot is .375 . I have my spindle ratio at 1 and my speed is set at 200 to 4000 rpm . I hope i gave enough info , thanks
