Y1 axis won't work

hi everyone, suddenly my y1 axis wont work, iv tried to swap the sides (right motor to y1 and left to y2)
and realized that the y1 output from the control box isn’t working - any ideas?

Open up your controller and check all plugs/pins and make sure they are fully seated.
Most likely in need for a board replacement, get in contact with Inventables

Done that, everything looks good inside.
Also trying to get some help from inventables.

Thank you though…

i lost the Y1 driver in my Xcontroller. wouldn’t do crap. they sent me a new board, but my machine was relatively new at the time
