FAQ
■Q1：The temperature or humidity is not accurate.
The temperature or humidity displayed on the screen are the values from the sensor's location and do not
represent the temperature or humidity at any other position inside the box. The temperature at the sensor's
location approximates the temperature near the filament, but it does not fully represent the temperature of the
filament.
When using an external thermometer to measure temperature, it is recommended to use a laboratory-grade
thermometer specifically designed for measuring AIR temperature. Household indoor thermometers, infrared
thermometers, food thermometers, and similar devices are not suitable for measuring the temperature of this
equipment.
The humidity value is only intended as a reference for changes in the internal environmental humidity of the
product and does not represent the moisture content or level of the 3D printing filament.
■Q2
：
The temperature cannot reach the set value of 70°C.
When setting the temperature to 70°C, please ensure that the heating level is set to the maximum (Highest) .
The heating time should be set for more than 1 hour. Additionally, adjust the exhaust vent opening to the middle
position. However, please note that if your ambient temperature is too low, it may not be possible to reach 70°C.
■Q3：The rotation function is not working.
a. Check if the motor is rotating properly. The built-in rotation motor has a lifespan of approximately 1500 hours. If
the motor has reached the end of its lifespan and is no longer functioning, you can visit EIBOS official website to
purchase a replacement motor. Refer to the motor's instruction manual for specific replacement instructions.
b. Check if the spool is jammed.
C. Examine if the spool is slipping on the roller shaft. If so, you can remove any sharp edges (such as mold lines) on
the edges of the spool. Alternatively, you can apply 3D printer adhesive or damping oil on the roller shaft to
increase friction.
■Q4
：
The fan alarm is displaying on the screen.
When the fan icon is blinking on the screen, it indicates an error in the fan system, possibly due to unstable
wiring connections or interference with the fan component by foreign objects. If the fan alarm occurs, please
contact EIBOS support email promptly for assistance.
■Q5：The temperature is displaying “LL” on the screen.
When the temperature displays 'LL' on the screen, it is due to a poor connection of the sensor interface, resulting
in inaccurate temperature readings.Therefore,if this error occurs, please contact EIBOS support email promptly for
assistance.
■Q6
：
How to perform regular maintenance.
a. When the spool rotates and rubs against the shaft, it can cause wear on the edges of the spool and result in the
accumulation of plastic powder inside the device. It is important to regularly clean the internal components of the
device to prevent any negative impact on printing. Please ensure to clean the device periodically to remove any
dirt or residue.
b. Regularly lubricate the internal gears. Add lubricating oil to the internal gears according to the specific
instructions provided by EIBOS. Visit the official EIBOS website to obtain detailed instructions on how to lubricate
the gears properly.
