Tip calibration:
Tip replacement requires Tip Calibration.
1. Select
Start Part
(flashing) - the printer will run two calibration parts.
• The printer will automatically build a Z Calibration part, measure
the part and calibrate the Z Axis for tip depth and tip level (approx-
imately 5 minutes). The Z calibration is automatic.
• The printer will then automatically build an XY Calibration part
(approximately 10 minutes). You must inspect the XY Calibration
part and calibrate the X and Y axis for tip offset:
2. When the XY Calibration part is complete the printer will display
Remove Part and Select XY Adjustment - X:0, Y:0
3. Remove the XY tip calibration part from the printer.
4. Inspect the part and calibrate the X and Y axis. See
Figure 54.
A. Use the magnifier from the Startup kit to view the support
road (shown in red).
B. Identify the location on the +X or –X side of the part where
the support road is best centered within the model
boundaries (shown in blue).
C. Read the number closest to this location. This is the required
X Tip Offset adjustment. If the number is on the -X side, a
negative offset is required.
D. Select
Increment
or
Decrement
to input the X offset
adjustment - the value will change in the upper display
window (by default, the printer will be ready to accept the
X value).
E. When you are satisfied with your X offset value,
Select Y
and repeat steps A- D to identify and input the required Y
Tip Offset adjustment.
