This cable is for adding a rotary/motor plug to your laser. It connects directly to your stepper motor driver. One end is wired to GX-16 4 pin male socket connector and other end has loose “pigtail” wires (crimped to quality ferules) that you can install (screw in) into standard green terminal bocks of your stepper motor driver.
