I checked the quadrature signals on an oscilloscope and they are getting to the Xulifeng USB BOB just fine. I connected X axis A and B channels to input pins 2 and 3 of the BOB with pull-up resistors. I enabled Mach3 encoder1 and put in pins 2 & 3. With the USB BOB, I shouldn't need to put anything in the port fields. I set counts/unit at 4000 just to get it going. I can scale it properly after I get it working.
My understanding is that is all it should take. When I move the X axis I get pulses on the input pins but no readout in the encoder field on the settings screen. What am I missing?
