Controller Connections
Follow these instructions to make the cable connections for USB interfacing, AC power in,
motor and sensors
The Mini-Mill's
CNC Stepper Motor Control Box (Controller)
outputs DC current, and is
supplied by AC current coming in from a 110 outlet (international 220 VAC). The power cord is
equipped with a 3-prong ground plug that must be connected to a properly grounded
receptacle for your safety. If an electrical failure occurs, the grounded plug and receptacle will
help protect the user from electrical shock. Only use a properly grounded outlet when running
your Mini-Mill.
NOTE: The power supply must be connected to a properly grounded receptacle for your
safety
NOTE: Do not attempt to make any connections to the controller while the power supply is
plugged in, or turned on. Unplug the power supply, and make sure the power switch is in the
off (down) position.
