Thanks for your reply. I do have a separate source which I will probably use on the final panel build but whilst experimenting its nice to keep it a bit more simple and use the on-board supply.
I had my first play with the Pokey 56U tonight and found it very nice to use. Set up a pushbutton switch, an encoder, a potentiometer, a toggle switch, some rotary switches and mapped them to Mach 3. Had a fair bit of success getting them to do what I wanted to do, but have a couple of issues you may be able to help with.
I've mapped the rotary switch to the step increments and they are changing fine on the Mach3 MPG screen, but when I turn the encoder 1 detent, it doesn't matter what step value is set, the axis only moves .0635mm This is OK as when I turn the encoder as fast as I can, its about at maximum speed for my steppers, I would just like it to be multiples of 10.
I want to use the toggle switch to turn block delete on/off. I assume I would need 2 inputs to Pokeys from this switch - 1 for on and 1 for off and map them to block delete on and block delete off. As this is controlled by a single toggle button in Mach 3, I guess I would need to create a separate on and off button in Mach 3 to get this to work?
Pokeys is seeing the potentiometer and I can see the voltage varying from 0-3.3v but I cant work out what DRO to map it to to get the feed rate override changing.
I'm sure I would eventually work these out, I guess I am just excited and want to get it all up and running.
