The printer makes noise

The 3D printer can make noises during printing, and these noises can have several causes. Here are some things you need to do to identify and fix your noise problem:

COOLING FAN:

  • Check the cooling fan on the extruder. If it is set to maximum speed, it may be noisy. From the slicing software, adjust the fan speed according to your needs. A slower speed may reduce noise without compromising print quality.
  • Make sure the fan propellers are intact and that they are not dirty or clogged with print residue or dust. If this is the case, turn off the printer and very carefully clean any debris or dust from the propellers or fan body.

NOISE LEVEL OF THE HANDLING AXES:

  • Make sure that the noise is not coming from the cooling fan on the extruder. If so, follow the directions above.
  • Check the smoothness of the pads on the moving axes by sliding them slowly with constant movements from top to bottom and vice versa. If there is friction and abnormal noise, you may need to contact technical support for maintenance.
  • Check the correct smoothness of the belt return bearings, which are located at the bottom of the slide rails. If the bearings are worn or damaged, they may be the cause of the noise.
  • Check the teeth of the belts. If you notice any expansion between the teeth of the belt or pinching, it may cause noise during printing. If so, you should replace the belt.

LOSS OF MOTOR STEPS:

  • Check to see if the printer’s motors are overheating during printing. Excessive overheating can cause loss of steps. Make sure the motors are properly cooled and are not clogged with dust or debris.
  • Check that the pulleys are firmly fixed on the motor shafts. Pulleys slipping on the shaft can cause lost steps.
  • Make sure the motor mount is stable and doesn’t move during printing.

EXTRUDER SHOCKS:

  • Check the leveling of the print bed. Keep a distance of about 0.1 mm between the nozzle and the print bed (thickness of an 80g A4 sheet).
  • Check the size of the print file. If the file exceeds the maximum print volume size, it may hit the walls of the printer. Set the correct parameters in the slicing software. (Starting with F20_rev6, F21_rev3, and F30_rev4 firmware, there is a software limitation.)
  • Check to see if any move plug-ins are installed when printing. Sometimes, these plug-ins can cause shocks. Make sure that the sum of the part width and the value of the plug-in does not exceed the maximum printable diameter. (Starting with F20_rev6, F21_rev3, and F30_rev4 firmware, there is a software limitation.)
  • Check that the extruder nozzle is securely fastened and is not unscrewed.
