Analysis of common fault causes
1.
The printing head does not output material or less
output material
· the print head did not reach a temperature of 170
℃
above (PLA), led to filaments cannot feeding.
· the material is knotted, resulting in poor discharge.
· the filaments were not delivered to the pipe and nozzle
accurately, resulting in the failure of normal discharge.
· the temperature of the extruder is too high, so that the
softening of filaments cannot be extruded normally.
2.
Motor shake, abnormal noise
· the motor line is loose and poor contact leads to
abnormal sound due to shaking. Check the wiring.
· the driving voltage is too large or too small, adjust the
driving voltage of the main board.
· motor damage.
3.
Unable to read SD card content
· it is not displayed when inserted on the computer. It
needs to be used after formatting SD card.
· there are illegal characters in the filename, and rename.
· the SD card is damaged and a new one is replaced.
4.
Model mismatch
· the belt is too loose, and the belt should be tightened
again.
· the jacking of the synchronous wheel is loose, and the
jacking is tightened again.
· the drive current of the motor is too high, and the drive
current is reduced.
