¶ Bad overhang quality
Cause: When printing the overhanging surface, the extruded filament is not cooled in time and bonds to the specified position, resulting in dropping, which is usually shown as follows:
It is recommended to try the following methods:
1. Enable support.
2. Reduce the print speed appropriately, or enable "Slow down for overhang", and further reduce the overhang speed if necessary (as shown in the picture below)
3. Properly reduce the nozzle temperature. When the overhanging part is printed at a slower speed, the nozzle temperature can be lowered for printing, which also helps to reduce the requirement for cooling.
4. Increase the speed percentage of the Auxiliary Part Cooling Fan and Cooling Fan for Hotend appropriately. If the overhang quality is consistently poor, please check if the Cooling Fan for Hotend and Auxiliary Part Cooling Fan works properly during the printing process. This can be tested by switching and adjusting the fan speed percentage in the slicer (as shown below).
5. Open the front door and the top glass cover of the printer for better heat dissipation. (This is generally only applicable to PLA, PETG, and TPU filaments. Operating in this way for other filaments may cause warping and weaker layer adhesion due to excessively low chamber temperature.)
