# Testing

When testing new processes or when learning new functions of the machine, use the following 3 procedures:

1\. Insert a pen into the end of the spindle and run the file on a piece of paper. Disable the spindle or the pen will spin.

2\. Set an imaginary surface above the material high enough that the spindle will still move up and down but never come in contact with the material.

3\. Use the Dry Run function.

Do not let the spindle run.
