-You must be signed off to use the Shapeoko 2. There are 2 ways to get signed off: +Training is required to use the Shapeoko 2. 
-  - **Class option:** Take a Shapeoko 2 introductory class (occasionally offered through Eventbrite). +To get trained, watch the CNC Orientation video (coming soon) and complete the online quiz with a score of 100%.
-  - **Self-guided option:** Read this wiki page. Once you have created your CAM design/GCode file, schedule a time with the CNC manager to demonstrating competency. You should be able to +
-  * Turn on and off the machine +
-  * Home the machine +
-  * Jog the machine +
-  * Use a workholding method of your choice +
-  * Change router bits +
-  * Set the zero position +
-During checkoff, you will perform your cut (it must be your own design)+
  
-If you need time in front of the machine to practice, email [email protected].org for permission to operate the Shapeoko for the purpose of learning. Then you will be permitted to setup, home, jog, and zero the machine. You may create your CAD/CAM design, but don't run your GCode or turn on the spindle until you are ready to get signed off.+Quiz access:

 +If you are new to CNC routers, performing an "air cut" with the spindle off prior to cutting solid material is recommended.

-The following instructions assume you are using [[http://easel.inventables.com|Easel]] for CAD and CAM, and for sending GCode to the controller. You can use other CAM programs, but Easel is the easiest for getting started because it walks you step-by-step through the sequence of operations for setting up and executing a cut.+You can use [[http://easel.inventables.com|Easel]] for CAD, CAM, machine control, and sending GCode to the controller.
  
 +You can also use Universal GCode Sender Platform (installed) for machine control and sending GCode while using other CAD/CAM software such as Vetric VCarve Pro for design.

-**May I use cutting fluid?** 
-Only if you find a way to contain the fluid without spilling it onto the MDF bed (you will have to make some sort of container mounted on the wasteboard). Otherwise, you can try using cutting wax instead. If you need to clear chips, use compressed air.
