● M2.0 Allen Key
● Phillips Screwdriver
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.
For this troubleshooting step, ensure that the printer is connected to the power source and turned on.
Click on the "Tools" ➞ "Control" ➞ "Module Calibration" ➞ "Position Calibration."
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.
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 and reinsert the cables at both ends of the calibration module. One end should be connected to the mainboard, and the other end to the bottom of the heated bed aluminum plate.
Refer to the link below to clean the calibration module.
This troubleshooting step requires a certain level of electrical knowledge and measurement equipment.
With the machine powered on, set the multimeter to the 20V DC range (Note: Different multimeter models might have different range settings, so adjust according to your specific model, ensuring the range is greater than 3V). Place the black probe (negative) on the second PIN from the top downwards on the mainboard calibration module port, and place the red probe (positive) on the first PIN from the top downwards, then measure whether the PINs on the mainboard have a voltage of 3.3±0.3V. If the measured voltage is within the normal range, then the mainboard is functioning correctly. If the measured voltage is outside the range, it might indicate a mainboard issue, and you may need to consider replacing it. (Note: This method involves working with live electrical components, so ensure electrical safety and follow the diagram for measurement positions.)
The above troubleshooting methods did not resolve 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.
