All of a sudden, my corexy steppers aren't working

[GeneRisi]

This may be something dumb, but I don't see it. The X and Y axis don't work but the Z axis does. I printed something a couple of days ago. I edited the config.g but don't see anything wrong.

Error: Homing failed

What did you edit? If it can't home properly anymore it won't let you move the motors.

[GeneRisi]

@phaedrux And it isn't moving the motors while trying to home. My problem is I don't think I modified anything significant... but either I did, or I have a new hardware issue. Can you see anything wrong?

[GeneRisi]

@generisi I found errors that make me wonder how it ever worked... It is fixed now - thank you!
