6) Flash jetting is normal when turning on. After printing for awhile, does not flash
jetting, but printing normally
：
a) Check whether the encoder is clean, or scratched, or not installed properly.
b) The config file is lost. Recalculate the machine length.
7) The interface of the software becomes grey. The movement cannot be
controlled. Extra solid color is printed
：
a) Check whether the USB cable is loosened or defective.
(Recommended to use
the cable with better anti-interruption)
8) Positioning error during printing
：
a) Check whether the 12V is normal
b) Check whether the X motor belt and the gear is loosened or damaged.
c) Check the X motor
d) Check whether the encoder is dirty or scratched.
e) Check whether the encoder sensor is dirty or defective
f) Check the connection of the 18P and 16P flat cable between the connecting board
and the printhead board.
（
Keep a distance from strong magnetic field. Prevent
using instable input power. Equip a UPS and stabilizer
）
9) Interruption during printing
：
a) Check whether 12v is normal.
b) Check the connection of the 14P flat cable between the connecting board and the
printhead board.
c) Check the connection of the cable from DB15 on the connecting board to the servo
driver.
d) Check whether the USB cable is normal.
e) Check whether the grounding is well.
10) Reset to home is normal. Carriage is moving, but not printing
：
a) Check the connection of the wire for the encoder.
b) Check the connection of the cable from DB15 on the connecting board to the X
servo driver.
11) Interruption when printing the printhead status. Ink jetting on the printing
platform when calculating the machine length:
a) Check whether the encoder sensor is connected properly.
b) Check the connection of the 18P flat cable.
