 7. Once the Automounter is running, you must define some positions. Positions are important because commands are only allowed to run from Minimum required are 'SOAK' and 'HOME' for most commands but it is recommended to defined various 'DRY_XXX' positions. To define a position, manually move the robot to that position using the pendent, and type in the position name, and tolerance and then click the save button on the operator screen.  The tolerance determines how sensitive the robot should be at that position.  Positions can be replaced by toggling the "Overwrite Position"  to ON before saving the position. For positions like DRY that have multiple sub-positions, use DRY as the prefix and save each one with a separate suffix.  Also, there is a different HOME position for each tool so you must save them separately always starting with the HOME prefix.
