Q3. Do we need to calibrate the extruder after replacing the nozzle?
Yes. It is recommended to perform extruder calibration again to ensure high print
quality as minimal error may be caused by extruder installation.
Q4 . What can I do if no filament comes out of the extruder after I choose the file
and the extruder moves normally?
1. Check the filament guide tube, and make sure the filament has been pushed into
the extruder; if not, please tap [Load] till filament comes out;
2. Check whether the nozzle is clogged. If so, please refer to Q1 for the solution.
Q5 . How to solve if the distance between the nozzle and platform is too
large(far away) or too small(hitting the platform)?
1. Tap [Maintain] - [Calibration]；
2. The printer starts pre-calibrating. The first point is to calibrate the initial distance between
the extruder and the platform (see Z-axis deviation value). Click the up and down arrows
to adjust the Z-axis deviation value. With the help of the leveling card, you can feel if there
is any slight resistance to decide the appropriate distance.
3. When it is still unable to properly print a large-size model after extruder calibration, or
when the model fails to be printed due to the uneven platform, please continue using
this function. The machine will perform 30-point automatic leveling. After the calibration
is completed, the software will automatically calculate a compensation mean value to
compensate. After the compensation is completed, the value is memorized and the
extruder is homed.
Whether the extruder assembly is in place is judged as
follows:
1.When installed, the extruder must be pushed to the
end;
2.Check whether the installation is in place：
①Touch the black buckle and the lower shell of the
white extruder, to make sure no hollows are felt；
②Observe to make sure there is no large gap in the
joint of the black buckle and the lower shell of the white
extruder.
