Switch # 1 set to ON changes the first axis to be closed-loop. Switch #2 affect the second axis in this way, etc.
Now, when you move the motor manually, you should see the DRO position display change on the screen. If it doesn't, then something is wrong with the encoder connection, probably. Note that switches 4-7 change the step/direction output to phase output. if you feed this to a microstepping drive step/dir, the moves would be constantly changing direction every 2nd (micro) step, and might appear to not be moving at all. I'm guessing that may be what you have done. If not, then we will have to investigate further. Other than making sure INPUT_SCALE has the right sign and scale factor for your encoder, nothing in your .ini file needs to change. (I believe I previously told you that input scale and output scale need to be the same. I think that's wrong, OUTPUT_SCALE needs to be either +1.0 or -1.0, whichever sign doesn't cause a servo runaway.) Sorry about the confusion on this, not too many people use this feature. But, it does work, I use it to test out my Gecko interface board. On a 3-axis closed-loop machine, you want switches 1-3 on, 4-9 off, and 10 on for the first USC board.
