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 .

I would definitelky leave the Home/limits on the parallel port so possibly the MPG would be the one to change over. I have not tested the MPG on the latest PoKeys plugin but I think it works reasonably well.

It works now, I did what hood mentioned and that corrected the problem. Thanks hood I appreciate your response .

Glad you got it Did you hook the MPG via the PoKeys? If yes does it work well

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

I did try it out with the Alpha plugin a while back but its totally different now, will have a look and see what you have to do but think its all plugin and you dont have to do anything in Mach.

Kind of looks like you would just select the MPG DRO in the drop down list on the plugin page.
