Stratasys uPrint - Calibrating Extrusion Tips

9. Replace head cover and close the printer door.
10. The printer will display Tip Maintenance - Tips Replaced? - press Ye s 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.
11. The printer will now begin to load material.
12. 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.
