Hi guys... I know I've done this before, but can't seem to get it working now.  The only emulated input that appears to work is the eStop.  I have keys set for limits and home on all three axes.  I see the LED's light in diagnostics, but when I hit the X home during a X reference nothing happens.  What am I doing wrong?   Thanks.

Please attach your xml.

i think you setup switch Y for Axis X and switch X for Axis Y.
