Z home issue was created by Bearfood
So after a few attempts I decided to take the advise of many and reworked my Z home limit switch so that it was at 4" wit a negative travel of -4". This is less than the current capability of the Z height but it'll work for now.

The issue I'm having is that it will home to the Z limit switch; upon hitting that limit the whole gantry makes a hell of a racket as it crashes back down to -4" much faster than it should. At first I thought that the motors lost power but when I tried it again a few times and hit the E-Stop it does stop as it's supposed to.

I checked the config and don't see anything obvious but that's not overly surprising.
Thank you!

Just a WAG but I would suspect that -0 is not a negative number

Just figured it out. I still had the home switch location set to 0 when it should have been 4. Odd that it would exceed the MAX Velocity values when it tries to come back to 0 but thanks for your help, it pointed me in the right direction.
