Thanks. it's giving a good direction.
Do you happen to have a component placement of the floorplan such that I can trace the given connections? There are three duplicate circuits which I believe relates to the signals you refer to, but I need more specific positions.
Additionally, do you happen to know what setting the MS3 should be set to?

Someone recently had a similar problem:

I suggest you read through that thoroughly. You may have a simpler problem - your direction pin may simply be loose. Or there may be a bad solder joint at one of those 2 pin shown in the circuit board. If the pins aren't bent and seem to be making good contact both at the arduino and the stepper, then I would swap the X and Y steppers to see if the problem moves to the other axis or not. I would also probe this signal at the driver.
