I hooked up my new black box to my minimill with high torque steppers, and can't get any jogging or movement to the steppers. It's all powered up except the steppers, I'm getting 24v out of my power supply, on the side of the black box I have a green light, and a red blinking light on the USB (see photo) (but yet the USB shows connected and connects in the software. the mill works fine with my custom controller so I know the steppers work, Is the box not powerful enough for the high torque steppers open builds sell? Is the blinking red light on the USB the issue? I can't find documentation on the lights.
