IDEX Homing problem

[Work Horse XL]

Hello, I have just finished a Idex design printer and can't figure out why the homing is having issues. Homing is great when you first turn the printer on and home from fresh boot. If you try and home it a second time after it's homed it start the X axis where it's currently located and only homes the U axis. Everything else seems to be okay. I'm just working this out and it could have other issues.
