Preface: This article covers issues related to powering up your Aurora Fiber laser. As you read this article, take note of the Visual indicators to make a judgement call of where power is passing and where it is not.

Please see this article for an Electrical Schematic of the 120V power:

3. Check the Machine Estop

Check that the Estop is not pressed. Give it a clockwise twist


4. Machine Main Breaker

Open up the top lid of the machine using the included Allen wrenches.

Remove the 6 bolts circled in the image below:




Inspect that the Main Breaker is in the ON position:

Off position:  Green Rectangle on the Breaker and the blue Tab is down
If it is in the on position, return it to the On position



On Position: Red Rectangle on the Breaker and the blue Tab is UP

5. Device Lights on Machine

Check for Lights on the control devices in the upper control panel. Knowing which lights are or or off can indicate where power is reaching and based off the status of other devices on the machine (plug, estop, breaker) further conclusions can be drawn. If you are unable to get the machine powered up, take note of the lights and pass that information onto the support team.
