I've run into a deal on an unused 4x8 Chinese router table and a controller. The controller is a Camtronics box with a main power supply and three G201's. The former owner never got the unit fully assembled.
It looks like the controller requires a 5V input thru a port on the back. What is the best way to add a 5V power supply?
Get it from your PC; a USB port cable is the most convenient way.
