Q3. Do we need to calibrate the extruder after replacing nozzle?

Yes, small errors may occur because of the calibration. To keep best printing
quality, you need to calibrate it again.

. What can I do if no filament comes out of the extruder after I choose the file

and the extruder moves normally?

. How to solve if the distance between nozzle and platform is too large(far

away) or too small(that they collide)?

Tap[Maintain]--[Calibration]；

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.

When the extruder is still unable to properly print a large size model after

calibration, or when the model fails to be printed due to uneven platforms, please

continue using this function. The machine will calibrate the remaining 8 points.

After calibration is completed, the software will automatically calculate a

compensation mean to compensate. When each point is being calibrated, the user

can also adjust the Z-axis deviation by clicking the up and down arrows. After

compensation is completed, the value is memorized and the extruder goes back to

zero.

Check the filament guide tube, make sure the filament has been pushed into the

extruder; if not, please tap [Load] till filament comes out;

check whether the extruder is clogged, if so, please refer to Q1.

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, 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.
