How to deal with the problem of “planing” during 3D printing?

The driving gear has sharp teeth, which can bite into the wire, and then rely on the rotation direction of the gear to push the wire forward and backward. If the wire cannot be moved, but the gear continues to rotate, the gear may scrape some plastic off the wire, so that the gear has no place to grasp the wire. Many people call this situation “planing”. Because too much plastic has been shaved off, the extrusion function is abnormal. If this happens to your printer, you will usually see many pieces of plastic scattered on the ground. You will also see that the extruder is rotating, but the wire is not pushed into the extruder. This paper introduces the simplest way to solve this problem.

1. Increase extruder temperature

If you’ve been having problems with shaving, try raising the temperature of the extruder by 5 to 10 degrees, so that the plastic extrusion is easier. You can click “edit process settings” to open the “temperature” tab to set. Select the corresponding extruder from the left side of the list, and then double-click the temperature setpoint you want to modify. Everyone must have a common understanding with magic monkey. Plastic is always easier to squeeze out when the temperature is high, so this is a very useful setting that can be adjusted.

2. Printing speed is too fast

After raising the temperature, if you still encounter the problem of shaving, the next thing you need to do is to reduce the printing speed. By doing so, the motor of the extruder does not have to rotate at that high speed, because the wire takes longer to extrude. Reducing the motor speed of the extruder helps to avoid the problem of planing. You can click “edit process settings” to open the “other” tab to set. Adjust the “default printing speed” to control the movement speed of the extruder when extruding plastic. For example, your previous printing speed was 3600mm / min (60mm / s). Try to reduce this value by half to see if the problem of planing disappears.

3. Check whether the nozzle is blocked

After reducing the temperature and printing speed, if you still have the problem of planing, the nozzle may be blocked and the consumables cannot be printed.
