Hi Andros, it seems to be working fine here in simulation so I am unsure why it is a problem for you.
Can you tell me, does the Y axis DRO show that it is moving? It does here.
I do notice there are no HotKeys set up for your axes, I am not sure if that will make any difference as it seems fine here but it may be worth trying to set them up anyway. To do that go to Config menu then System Hotkeys. Click on X++ and a box will pop up asking for you to press a key, click you right arrow. Next X-- and press Left arrow, move to Y++ etc and do them all.
