Program Origin - EFD Ultra 325TT User Manual

A NORDSON COMPANY
Program origin is the (0,0) coordinate for the program. All points in the program are relative
to this location.
i. Origin is the physical position that all moves are based upon.
ii. The origin is used to allow for negative X/Y moves for needle offsets.
iii. If home position is taught as origin, then negative moves cannot be
accommodated for dispensing tip offsets.
iv. The origin for a particular part can be either a specified fiducial on a part
or a reference point on your work-holding fixture.
v. The origin is often taught at the first point in a program
The program origin is the primary reference for all other points in a program. If the origin point is
moved, then all other points will move along with it. This is how dispensing tip offsets are
managed. The system can be programmed to adjust origin (offset tip location) at run time. This
will require the operator to validate or teach the tip location every time the machine is cycled.
In order to create global Z adjustments, it is important to note that all Z- coordinates are displayed
in absolute numbers.
