Wicked weather right now made me think, is it cold in your shop?
If it's marginally cold, I'd try going into the Configuration menu and running a cut motor test to see if you can start it up manually.
That might give you a more usable error code too, if it doesn't start up.
If it does start then you can warm up the flex shaft a bit by letting run.
That Y axis stall is from it crashing into your board without the cut motor running.
How many hours are on your machine?
Worn brushes, or a loose/bad connection are two other possibilities that come to mind.
