Steps 1-4

Step 1

Do not power on the machine yet. Turn the knob on the back of each stepper motor. They should be turned easily and the respective axis should move as these are turned.

Turn the “POWER” switch on the machine on. The motors should be self locked now. Once again try to turn the knob on each stepper. This should be much harder to turn now and not easily moved.

This means that the steppers are connected to the controller and are able to be controlled.

Step 2

Ensure the USB cable is connected to the computer and the controller. Run Mach3. If the “RESET” button is flashing, click this button to allow Mach3 to control the OMIO.

Step 3

The arrow keys should now be able to move the machine. Be careful moving the machine at this point. There are still some checks to be done.

• X-/X+ controlled by Left/Right Arrow

• Y-/Y+ controlled by Down/Up Arrow

• Z-/Z+ controlled by Page Down/Page Up

Pressing the tab key on the keyboard will bring up the manual jog controls in Mach3. Jog the machine using this option as well to ensure everything is moving as expected.

Step 4

If the machine is not jogging in the direction that is expected, this can be changed in the setting of Mach3.

Go to Config -> Ports and Pins -> Motor Outputs. Look at the column “Dir LowActive” to change the direction of an axis. Click the check mark or X to change the direction. The mark should flip between the two options.
