Y axis not working - Machine stopped moving on Y axes

▶  Description of the problem

Nothing happens when you press the Y keys on your keypad nor the Y arrows on your screen. 

The Y axis remains static in Y+ and in Y- . 

When you press the "home" button: Z and X work great but Y doesn't move. On the screen, the Y coordinates decrease continuously showing that PlanetCNC thinks Y is moving, but it isn't.

 ▶  Possible origin

Something interuppted the "Gantry Squaring" procedure (it could be either an Emergency Stop, the standard stop, a limit activation on X or Z, or any other reason...); and now the machine is stuck in a squaring status in which the Y axis can't be controlled.

▶  Step by step solution

1. Press Stop if your coordinates are still moving.
Then Go to File > Settings 

2. In Motors check if Axis Output 2 and 4 are set U & V (this is the squaring setup).
Change their values to set both to Y.

3. Click OK to save, and you’re done. 
Launch a Home and let the machine finish it.
The Y axis should now be working normally.
