Turn off the switch, move the extruder to four corners along XYZ axis, and
separately adjust the springs to control the distance between the extruder and
plate(Theoretically it should be about the thickness of a piece of A4 paper) and
reconfirm for several times(Please be careful not to overexert in case the
extruder would damage the platform). And then separate the extruder and
plate by hand or software to a distance for at least 5cm.
2.Common fault and exclusion
No wire out from the nozzle
①
Check if the extruder works in normal status
②
If the extruder blocked
③
If the
nozzle temperature set well
No wire for the first layer
①
The extruder is too closed to the platform
②
The ABS/PLA material has not
got into the nozzle
③
If the temperature set correctly
The first layer can not stick to the platform
Distance between extruder and platform is too far
The tape on the platform is Kapton tape
Platform is not in levelling status
The surface of printed sample is foaming
The layer thickness is set to large
The printing speed is too fast
Temperature is set too low
The wire sender is abnormal
The diameter of the filament is not suitable
Setting of filament temperature
There is a little difference in suitable temperature for different filament.
The
temperature range for PLA filament is 185
℃
±10
℃
, and 225
℃
±10
℃
for
ABS type.
So we should set the temperature according to the practical
abservation. If the printed samples can be broken very easily, it indicates that
the temperature is too low. If the wire is too thin, then the temperature is too
high. The PLA filament would turn into liquid status if the temperature is too
high. The printing speed and size of the models would also affect the filament
temperature setting. The filament can be fully preheat for lower speed, so it
may result in the wire-sending error if the temperature is set to high, and this is
the reason why we meet the error of no wire out when printing small models.
