The pins differ from the default GRBL pins.
The shield uses the following pins.
Step X = D2
Step Y = D3
Step Z = D4
Dir X = D5
Dir Y = D6
Dir Z = D7
Spindle output = D12
The voltage for driving the motors comes from the Vin pin on the Arduino. This requires you to use a 12v power supply to power the Arduino.
