¶ Required Tools for Inspection:
● M2.5 Allen Key
● Multimeter
¶ 1.Check if the Buttons Rebound Properly
Troubleshooting Method:
Gently press the buttons by hand and observe whether they can be smoothly depressed and rebound. If they do not rebound properly, use an M2.0 Allen wrench to slightly loosen the screws behind the module until the buttons can be pressed down and rebound normally.
¶ 2.Confirm if the nozzle is positioned above the calibration module.
Troubleshooting steps:
¶ Step 1: Turn on the printer.
For this troubleshooting step, ensure that the printer is connected to the power source and turned on.
¶ Step 2: Perform position calibration.
① On the main interface, rotate the knob counterclockwise to select the settings icon, and then press the knob to enter the settings menu.
② In the settings menu, rotate the knob clockwise to select "Module Calibration," and then press the knob to enter the calibration menu.
③ In the calibration menu, first rotate the knob clockwise to select "Position Calibration." The machine will automatically probe and stop near the calibration module.
¶ Step 3: Verify the nozzle's position.
After completing the above steps in sequence, observe whether the nozzle is positioned above the center of the calibration module.
① If so, there may be a poor connection with the cable. Please proceed with the checks as outlined in point 3.
② If not, it might be due to the nozzle not making contact with the calibration module, resulting in an error. You can adjust the nozzle to be above the center of the calibration module using the interface's movement distance unit and X/Y axis movement directions. After adjustment, click "Save," and then perform the auto-leveling process once again.
¶ 3.Poor cable contact
Troubleshooting steps:
¶ Step 1: Turn off the printer
Before proceeding with the following troubleshooting steps, make sure to turn off the printer and disconnect the power for safety.
¶ Step 2: Disassemble the printer bottom cover
① Place the printer flat with the bottom facing you. Use an M2.5 Allen wrench to loosen the four screws securing the base cover counterclockwise.
② Gently pry open the base cover at the cable outlet in the lower-left corner. Be careful to avoid damaging any components.
③ Disconnect the mainboard cooling fan (FAN2) cable fixed on the base cover. Handle it with care to prevent any damage.
¶ Step 3: Reconnect the cable
Reconnect both ends of the calibration module cable.
¶ Step 4: Clean the calibration module
Refer to the link below for cleaning the calibration module.

¶ 4.Hardware failure
This troubleshooting step requires some electrical knowledge and measuring equipment.
Troubleshooting method:
With the machine powered on, set the multimeter to the 20V DC range (Note: Different models of multimeters may have different range settings, so adjust accordingly, but make sure the range is greater than 3V). Place the black probe (negative) on the second PIN from the top of the mainboard calibration module port, and place the red probe (positive) on the first PIN from the top. Measure whether the mainboard's PIN has a voltage of 3.3±0.3V; if the measured voltage is within the normal range, the mainboard is normal. Otherwise, if the measured voltage is not within the range, it may indicate a problem with the mainboard. Please try replacing the mainboard. (Note: This method involves working with electricity, so pay attention to electrical safety and measure according to the corresponding positions in the diagram.)
If the previous troubleshooting methods were unsuccessful in resolving the issue. We recommend that you create an after-sales ticket 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)
