Power on movement

[r0nn1ef]

I have a M3 that is driven with an Raspberry Pi with the Arduino board both plugged in to a power strip. Whenever i toggle the switch on the power strip to turn everything on, the cnc moves the X and Y axis to the far left and front of the bed ... both past their limits and it makes a horrible sound. Is there any way to tell Arduino to not move when the power is turned on?

What is the grbl command for that?

in ugs setup there should be a radio button; don't know the $sxx. You can also switch axis directions, etc.
