Hi,
Started working on my shapeoko build a few days ago and found one problem: If I power up Arduino first before gShield is up, gShield will enter an unusable state: hum sound is heard (probably from the steppers), steppers won't move for any gcode. Pressing the reset button will fix it:

However if I power up gShield before the Arduino, it works perfectly well. It is something expected? Do you guys have any idea?
Configuration:
gShield: v5b
grbl: v0.9i
Arduino Uno
Will be very grateful for any help.
Thanks,
-Ivan
