X, Y, and Z offset calibration
1. Follow standard steps for Tip offset calibration.
a. Start FDM Status.
b. Click the Calibration button.
· Specify the properties of the modeler in the Configure Modeler window. This
is much like the configuration window in Insight.
Specify the: model & support material types, model & tip sizes, and
the slice height
c. Click to confirm the modeler configuration parameters. These parameters
will determine the values used to build the calibration box used to set the tip
offset values.
d. The Calibration window is displayed.
e. Choose Cal boxes and Tip offsets as the type of Download data. For tip-offset
calibration, you will want to download the current offsets and a calibration
box.
f. Click the Download button to build an initial calibration box using the
current modeler configuration and offset values.
g. The FDM Pause light will start to blink. Press the Pause button to initiate the
XYZ homing procedure. When the Pause light starts to blink again,
the extrusion head will be in the front-left corner. Lower the tip so that
it is touching the foam. Press the Pause light again to start building
the calibration box.
h. Verify the results, and modify the X and Y offsets to position the support
material directly on top of the model material. Do this by clicking the
+/- X and +/- Y buttons to shift the location of the support material
bead. You can also enter numeric values for the X and Y offset incre
ments.
i. Repeat steps 7 through 9 as necessary until the support material is centered
on the model material.
j. After completing the X and Y offset calibration, peel away the support mate-
rial layer from the final calibration box. Measure the Z-thickness of
thesupport material bead using a caliper or micrometer. The thickness
should be 0.010 inches for the T16 tip.
k. If the support bead is too tall or too short, use the +Z and -Z buttons to
change the Z offset.
l. After changing the Z offset, build a new calibration box by clicking the Down-
load button.
m . Repeat steps 11 through 13 until the support-material bead is the correct
height.
Use these additional steps to fine tune the calibration:
1. Close the Calibration window.
2. Open Set Preferences.
a. Check Allow Stripped File Download.
b. Close the Set Preferences window.
3. In the FDM Status main window, open the Pack and Download window.
