[ Manual E2 - How to Adjust the Height of Left and Right Nozzle – V1.0 ]
Required Tools:
①2mm hex wrench
②Feeler gauge
1.Select the "Setting" icon to enter the Setting interface.
2.Select the “Maintenance” on the Machine tab.
3.Select the “Offset Calibration”.
4.Confirm that all the requirements of the prompt are met and select “Start”.
5.Run the first to fourth steps of the wizards in turn, the wizards have complete operating instructions, please follow the instructions.
6.After completing the first to forth steps, select the “Offset Settings”.
7.If the left and right nozzle offset value difference is less than or equal to 0.15mm, indicates that your printer's left and right nozzle height differences are within acceptable limits,
if the left and right nozzle offset value difference is greater than 0.15mm, you need to continue to adjust the height of the left and right nozzles.
8.First, unload the filaments in the left and right extruders, please select “Utilities”>“Filament Loader”> “Unload” to unload the filament in the left and right extruders.
Select "Home" and wait for the nozzle’s temperature to cool down before proceeding to the next step.
Note: If there is residual filament on the nozzle, please clean it briefly first, otherwise it may cause slight errors in the data (Please wear insulated gloves to prevent burns when cleaning).
9.Select the “Move Axes” in the Utilities tab and select the “Home All” to return the Y and Z-axis and both extruders to their original positions.
10.Select the Z-axis in the top right corner of the screen, select the “1.0mm”, then select the up arrow twice to raise the Z-axis by 2mm.
11.Select the “Motor Unlock” icon on the right, the touch screen will display “The motors have been disabled”, select “OK”.
Note: After the touch screen displays “The motors have been disabled”, you can move the extruder and the heatbed by your hand.
After you use the touch screen to control the motor, the motor will be locked.
12.Manually align the center position of the heatbed under the X-axis beam, then move the left and right extruder to the center position of the X-axis beam, and then place the feeler gauge under the left and right extruder, select the down arrow to lower the Z-axis until any nozzle contact the feeler gauge, and then align the small frosted dots with the left and right nozzle to feel the friction between the small frosted dots and the nozzle.
Note: The three options in the Move Steps allows you to select the distance of how much the Z-axis falls.
To prevent the damage to the heatbed from falling too fast, it is recommended that you can select 0.1mm and lower the nozzle slowly,
and then move the feeler gauge around to feel the friction between the nozzle and the dot.
13.If the friction of the left nozzle is larger than that of the right nozzle, it means that the height of the left nozzle is lower than that of the right nozzle,
and if the friction of the right nozzle is larger than that of the left nozzle, it means that the height of the right nozzle is lower than the left nozzle.
The following figure is a demonstration showing that the left nozzle haves a greater friction than the right nozzle, then adjust the right nozzle height according to the left nozzle height.
Note: If the right nozzle has been adjusted to the limit position and cannot be adjusted, then adjust the left nozzle in a similar way.
1) Move the left extruder to one side, use a 2mm hex wrench to loosen the right nozzle clamping screw,
gently loosen the entire hotend with your hand so that the nozzle can naturally drop onto the feeler gauge, and tighten the right nozzle set screw.
Note: The nozzle is still warm, so make sure the nozzle cools down before operating it.
2) The left nozzle can be adjusted in the same way as in the above steps, move the right extruder to one side,
use a 2mm hex wrench to loosen the left nozzle clamping screw, gently loosen the entire hotend with your hand so that the nozzle can naturally drop onto the feeler gauge,
and tighten the left nozzle clamping screw.
3) Move the right extruder back above the feeler gauge and feel the friction between the two nozzles with the feeler gauge again.
If the sense of friction is different, continue to fine-tune the nozzle height until the sense of friction of the left and of the right is basically the same.
Note: The nozzle should be aligned with the frosted dots on the feeler gauge.
4) After adjusting and reinstalling the screws, select the "Setting" icon and select “Offset Calibration” in the “Maintenance”. and run the Five-Step Wizard of the left and right nozzle again.
5) When the left nozzle and right nozzle calibration wizard is finished, compare the left and right nozzle offset value,
if the difference is less than or equal to 0.15mm, it means that the left and right nozzle height have been adjusted properly,
If the difference is larger than 0.15mm, it indicates that the left and right nozzle height offset is too much,
please return to step 8 to readjust the left and right nozzle height until the difference is less than or equal to 0.15mm.
Note: The same material needs to be used in the left and right nozzle offset calibration, otherwise there may be data errors.
