Hello,

I'm out of ideas on how to wire the 6 PIN MPG. Could anyone help with wiring? The picture below shows how I wire the MPG. I change settings in the UCCNC
MPG A Pin 10, Port 2;
MPG B Pin 11, port 2.

But can't get this thing working. Thank you for your help!

the problem is the ucbb inputs have 2k2 resistors on their inputs and are designed for 24v input and you are trying to get good quality signals from what I presume is a 5v output mpg.....

you need to get a 26pin Bob or a lpt Bob with a 26pin idc >> 25pin lpt port cable and wire it direct to the uc300eth spare ports or pins...

It may work with 5 volts, but the connection on the drawing is bad. Try the following. (You can also try to connect A- and B- instead of A and B.)

Thank you very much for your reply and suggestion. I have IDC26 breakout board and will give it a try

Thank you for your input. I will add 0v wiring as per your modified diagram.

Thank you, gents! Your help is much appreciated!

I have tested both suggestions.

dezsoe - Your suggestion did not work I wired as per the corrected diagram and I can see that UCBB CN1 light is blinking when I rotate the MPG. But when I open the pin mapping plugin or diagnostics page - only A input is working and in some strange manner - registers only every fifth or sixth encoder pulse (even if the UCBB registers the every pulse input by blinking the led). I have tried to wire A-;B-; but the issue is the same.

Robertspark - Your suggestion did the trick! I used breadboard wires and wired directly two wires from port 3 pin 10 and pin 11 to A and B MPG terminal and it works without any issue now!

Many thanx for Your help gents!

I have the UCR201 wireless CNC jog pendant and I really like it. But once I plug the UCR201 adapter into USB, my newly panel-mounted MPG stops working. Is there a way to have both JOG pendants?

Thank You

OK, that's why I wrote "may work". It depends on how the outputs are driven in the MPG.

No, you cannot use 2 MPGs.

Thank you dezsoe.

I was wondering if the panel-mounted MPG could be assigned to "normal" jog functions (used instead of the keyboard) and the MPG would be the actual handheld device? That way I could have two MPG controls (one on panel, one handheld if needed).
