Stepper Motor Connector.
One for Each Axis, X1, Y1, X2, Y2.
All operate independently.

For each motor there is a current adjusting trimpot.
Next to each trimpot is a test point.
The voltage at the test point will reflect what the phase current will be for that motor.
Doubling the voltage read will equal the phase current setting.
For each motor there is a set of jumpers that define the steps per revolution for that motor.
The possible settings are 400, 800, 1600 or 3200 steps per revolution.
