¶ 1. TH-MAX: Nozzle temperature sensor short-circuited causing the temperature to be too high, the touch screen display temperature exceeds 275℃.
¶ Examination steps:
¶ (1) Check whether the corresponding wiring connections of the temperature sensor on the main board and effector are loose or incorrectly plugged in
¶ (2) If there is no problem with the line connection, please replace the nozzle temperature sensor in the package for testing.

¶ 2. TH-Runaway: Nozzle temperature is reduced by more than 20℃ within 40s.
¶ (1) Check if the silicone sleeve is installed on the heating block
¶ (2) Check if the nozzle's heating rod and temperature sensor are loose, if loose, please re-fix them
¶ (3) If there is no problem with the above troubleshooting, please replace the nozzle heating rod in the package for testing.

¶ 3. Heating failed: temperature did not rise 2℃ within 32s.
¶ (1) Check whether the nozzle heating rod and temperature sensor are loose, if loose, please re-fix them.
¶ (2) If there is no looseness, please replace the heating rod of the nozzle in the package for testing.
¶ 4.TH-MIN: Nozzle temperature sensor disconnection caused by the touch screen display temperature is lower than -5 ℃.
¶ (1) Check whether the lines corresponding to the temperature sensor on the main board and the effector are loose, and re-plug to ensure that there is no looseness in the plugging.
¶ (2) If the line is not loose, please replace the nozzle temperature sensor in the package for testing.
¶ 5. TB-MAX: The temperature of the hot bed temperature sensor is short-circuited causing the temperature to be too high, and the temperature displayed on the touch screen exceeds 115℃.
¶ (1) Check whether the corresponding lines of the hot bed on the motherboard are connected correctly
¶ (2) If there is no problem with the line connection, please dismantle the lower case of the machine under power-off condition and manually press the heating rod and temperature sensor of the hot bed to ensure that the line is not loose. If still can not be solved, please feedback the above information to the after-sales e-mail: service@flsun3d.com.
