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
