The ringing wavy texture is a undulating texture that appears on the surface of the print, primarily due to vibration or sway on the 3D printer. Typically, you will find this texture when the extruder suddenly changes direction, like a sharp corner. For example, if you are printing a 20mm cube, each time the extruder goes to print the other side, it will change the direction of motion. When these extruders suddenly change direction, they will vibrate due to inertia and will be displayed in printing. We'll look at the most common methods of locating ring patterns and test them item by item.
Printing speed is too fast: The most common cause of ringing is that the printer is working too fast. When the extruder suddenly changes direction of motion, this rapid movement will create additional forces that cause accompanying vibrations. If you feel that the print speed is too fast, try reducing the print speed. You will need to adjust the value of the "Speed" of the "Print Speed" and "Advanced" pages of the "Basic" page. The first controls the speed of the extruder in the extruded state, while the second controls the extruder without the speed of movement in the extruded state. You may need to adjust both parameters to see the effect.
Firmware Acceleration: Firmware running on the electronic part of the 3D printer typically has acceleration control to help prevent sudden changes in direction of motion. The acceleration setting will cause the printer to ramp up and then slow down slowly before turning. This feature is the key to preventing ringing. If you have the ability to modify your firmware, you may need to try to reduce this acceleration to get a slow speed change. This will better reduce the ringing pattern.
Mechanical problems: If there is no effective way to solve the ringing pattern, then you need to find the reasons that will cause excessive mechanical vibration. For example, there are loose screws or broken brackets that cause excessive mechanical vibration. Observe your printer at close range during operation to identify the source of the vibration. We have encountered many users who are ultimately tracking the mechanical problems of the printer, so when the above suggestions are invalid, it is worthwhile to double check the mechanical part of the printer.
