reomoved covers and moved X stepper motor and then it rehomed.
Likely a User had driven  the X motor and stage mechanicals hard to zero point, tripping the XYZ stage overtravel sensors.  Errors observed were E1 initially then E4 after that.  Usrs is back on system and system is back up in niormal modes...
