TESTING THE PRINT JETS AND EXTRUDERS
When material fails to come out of the print jets during a print, you may receive a warning message on the
display. The CONTROL JETS function from the Print Jet Calibration menu is a utility that enables you to test
the print jet heating elements and the extruder operation.
Navigate to the Print Jet Calibration screen and select CONTROL JETS.1.
Select the print jet you wish to test.2.
Select the target temperature value twice to read 260°C.3.
NOTE: To increase or decrease the temperature value, press the up or down arrow.
NOTE: The typical printing temperature for ABS print material is 260°C. The typical
printing temperature for PLA material is 220°C. For best results, leave the default
target temperature at 260°C while extruding print material from the Control Jets test
utility.
NOTE: The current temperature reading will appear above the target temperature
value.
Once the temperature has reached 260°C, select the speed value.4.
NOTE: Pressing the speed value twice will place the value at 4.0 RPM. Press the up or
down arrows to increase or decrease the extrusion speed.
