[Sonic Mega 8K S] Checking the Z-axis and Motor

Cleaning the Z-axis

If you're experiencing issues with your Z-axis, start by checking the lead screw for dirt or debris. If it's dirty or has accumulated grease, use a microfiber cloth to wipe it clean. You can also use alcohol for deeper cleaning. After cleaning, consider lubricating the lead screw. For more detailed instructions, please refer to Z-Axis Cleaning

If the Z-axis is still unable to move after cleaning, proceed to the next steps

Reconnect the motor connectors

Checking the motor cable connection on your Sonic Mega 8K S is an important step in ensuring that your device is working properly. If the motor cable becomes disconnected, it can cause your printer stop working altogether. To check the motor cable connection, follow these steps:

1. ⚠️Note: Always disconnect the power source before disassembling any electrical equipment. If it is necessary to handle equipment that is still plugged in, ensure your hands are dry and consider wearing insulation gloves, protective clothing, and shoes with insulated soles if possible.

   
   
   1. Turn off the printer.
   2. Use an Allen Wrench (Size 2) to loosen the 12 screws and open the front case.

    

   3. Carefully keep the cables intact and place the front case in front of the printer.
   4. Check/reseat the motor cable on the two ends.

    

   5. Insert the power cord and turn on the power.
   6. Remove the building plate and resin vat.
   7. Manually run the Z-axis to verify if it runs correctly.

Check the Z-axis by turning it by hand

If you experience a situation where the Z-axis becomes stuck during printing or if you hear a grinding noise from the motor, it may indicate a problem with the Z-axis mechanism. This issue is often caused by the buildup of dirt, dust, or resin on the Z-axis or even resin that has seeped into the motor, preventing it from moving smoothly.

To check if the motor is working properly, follow the steps below:

1. 1. Turn off the printer.
   2. Remove the building plate and resin vat.
   3. Use the Size 2.5 Allen Wrench to loosen the upper screw.

   

    

   4. Spin the couple by hand to check if the motor is spinnable.
   5. Spin the ball screw by hand to check if it is spinnable.
   6. If the ball screw does not move, try cleaning and lubricating the ball screw with spindle oil.

    

Regular maintenance of the Z-axis and lubrication can prevent this issue from occurring.
