Tip Depth Calibration - Stratasys Dimension 768/Elite Service Manual

Tip Depth Calibration

Adjusting Tip Depth (Foam)
Build And Inspect the Tip Depth Calibration Model:
1. Use the control panel to build the "test_tipdepth.cmb" model.
2. After the part is completed, remove the modeling foam and inspect the raster patterns of
each two raster set. For tip depth to be set correctly, the left raster pattern of each two raster
set must be flush to below the surface of the foam in all 5 raster sets. The right raster pattern
of each set must be partially above the surface of the foam in 3 of the 5 raster sets.
Above flush:
in 3 out of 5 sets
Flush to below flush:
in all 5 sets
Raster depth can be verified by running a thumbnail along the surface of the foam over the
edge of the rasters. If the raster is flush or below flush, your thumbnail should not catch the
edge of the pattern. If the raster is above flush, a thumbnail will catch the edge.
Update Tip Depth Compensation Value:
1. Start Maraca and select the Current Modeler from the pull down menu.
2. Click on the Tip Offsets button. A window with a Tip Depth field should appear. The tip
depth value is in inches and refers to the distance from the normal Z zero that the tip will
be shifted into or out of the foam. A negative correction causes the tip to build deeper into
the foam.
3. In the Tip Depth field, enter the new tip depth value. Then click the check mark to accept
values. New value = Old value + identified correction. For example: If the current Z offset
is
-0.045", and the tip is 0.015" too deep in the foam, the new Z offset should be 0.030".
4. Toggle the front panel power switch to restart the software and activate the new values.
5. After the machine returns to idle, check the Z offset using the same method described
above.
