9. Replace head cover and close the printer door.
10. The printer will display Tip Maintenance - Tips Replaced? - press Yes to begin material
load.
a. The printer will display Load Model - Replace Both Carriers
(flashing).
• If you want to replace a material carrier, do so now.
• If you do NOT want to change a material carrier, you must unlatch and latch
the carriers to continue (Push the carrier forward to unlatch, then push it
forward again to latch). Because the material ‘unloaded’ during the tip
replacement, the printer is in the material replacement mode. You must
unlatch and then latch the carriers to continue. If there is a delay in the
unlatch/latch process, the printer will display Both Carriers Not Replaced Or
Invalid
. Select Retry, then unlatch and latch the carriers.
b. The printer will now begin to load material.
c. After material loading is complete the printer will display Tip
Calibration - Install Modeling Base And Build Calibration Part.
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 (approximately 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 45.
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).
NOTE: If the head cover is not replaced the printer may not function properly.
NOTE: Make sure a NEW modeling base is installed before starting
calibration. Calibration results will be incorrect if a NEW modeling base is not
used.
