Before proceeding with troubleshooting, make sure to turn off the printer and disconnect the power to ensure safe operation.
Hold the latch on both sides of the touch screen cable to remove it, and then take the cable out of the slot.
① Use the M2.5 Allen Key to unscrew the 2 screws fixing the bottom plastic parts;
② Use a Phillips screwdriver to pry open the plastic parts along the indicated direction;
③ Take out the touch screen cable from the plastic parts;
④ Unplug the FAN2 fan cable on the mainboard and set aside the plastic parts.
Reconnect the Hotbed T1 cable on the mainboard.
This troubleshooting step is performed when the device is not heated.
Power on the machine and observe whether the temperature displayed in the upper left corner of the main interface is normal. The normal room temperature is generally around 25°C and is related to the ambient temperature. If the ambient temperature is lower, the displayed temperature will also be lower. If it's below 10°C, you might see this prompt. In this case, move the device to a warmer area for use.
This troubleshooting step requires some electrical knowledge and measuring equipment. Due to different brands of multimeters having different measurement ranges, adjust the multimeter to the suitable range.
With the machine powered off, use a multimeter to measure the resistance of the Hotbed NTC cable (T1) at room temperature (25°C). The resistance value should be around 100±15KΩ. If not, it might be an issue with the Hotbed. Try replacing it.
(Note: This method involves working with electricity, please ensure your safety and follow the diagram below for measurement.)
With the machine powered on, set the multimeter to the 20V DC range. Place the black probe (negative) on the 2nd PIN of the mainboard T1 port from the top down, and place the red probe (positive) on the 1st PIN from the top down. Measure whether the NTC PIN on the mainboard has a voltage of 1.8±0.3V. If the measured voltage is within the normal range, the mainboard is normal. Otherwise, if the voltage is out of range, it might indicate an issue with the mainboard. Consider replacing it.
The above troubleshooting methods did not resolve the issue.We recommend that you create an after-sales work order to provide the after-sales engineer with feedback on the previous inspection process and results. The after-sales engineers will assist you in finding a solution to the problem(Reply time :1 working day)
