Using the Dry Run feature in the vision software is a great way to verify your positioning prior to engraving on your project. You may want to increase or decrease the Dry Run Speed based on your particular project (i.e., set a slow dry run speed when engraving in a small area).
Go to Menu>Configuration>Dry Run Speed
Pressing Enter with this item highlighted will allow you to enter your desired XY speed of the motion system (measured in inches per second). Use the numeric buttons to enter the desired speed, and then press Enter to save this speed.
