Hi,
This is the old defective board.
If i dont try to Home the printer or move any stepper it wont show a short and M122 seems good.
But i ran the M122 after trying to home and this message came up.

You can see the picture i posted.
I ran an emergency stop and it reseted and i ran a M122 and the same as i posted first came up.
I hope this helps to get a better picture of my issue with this board.
