Hello,

I just finished setting up my Onefinity PRO Series Woodworker, but there is an issue:

The control box doesn’t turn on when I press the ON/OFF button.

- I opened the box and saw that the ON/OFF switch was not connected.

- I also noticed a yellow wire coming from the blue connector inside the box, but it is cut and not connected to anything.  
→ Can you tell me if this wire should be connected somewhere?

How to to fix it ?

Please send an email to [support@onefinitycnc.com](mailto:support@onefinitycnc.com) for assistance.

That snipped wire is snipped on purpose as it’s not used.

It is not recommended to open the controller unless directed to by support.

We ship our control boxes with the big red estop button pushed in/engaged. The control box will not power up when the estop is engaged.  
Please twist and pull up the big red estop button to disengage it so the control box will power up.
