12. Nozzle Fan Settings 喷头风扇设置
1 As shown in the figure above, the fan air will increase by rotating the knob clockwise and will decrease by rotating the knob counterclockwise.
如图所示，顺时针旋转旋钮，风扇风量会逐渐增大；逆时针旋转旋钮，风扇风量会逐渐减小。
2 Turn the knob clockwise to the maximum (and scale 10) before printing; the pure PETG material is rotated to the scale range of 4-6 prior to printing.
在使用本公司提供的耗材中除却纯PETG材料外，其余材料在打印前需把此旋钮顺时针旋转至最大（及刻度10）；
纯PETG材料在打印前需把此旋钮旋转到4-6这的刻度范围内。
3 When printing and testing other particle consumables of unknown brands, rotate the knob clockwise to the maximum (and scale 10) before printing,
then preheat the nozzle and then the extrusion material. If the extrusion temperature is correct (i. e., the correct extrusion temperature of the material),
the output is smooth and the feeding state is normal; print the material according to the standard of the scale 10.
If the extrusion temperature is correct (i. e., the correct extrusion temperature of the material), the material is not smooth, try to rotate the knob counterclockwise,
adjust one scale each time, adjust to wait 1-2 minutes to squeeze out the material again, until the extrusion is not stuck.
在打印测试其他未知品牌的颗粒耗材时，打印前先把旋钮顺时针旋转至最大（及刻度10），再预热喷头接着挤出材料，
在确认挤出温度无误（即材料的正确挤出温度）的情况下，如未出现挤出电机卡顿，出料顺畅，出料状态正常；
则按旋钮在刻度10的标准去打印该材料。如在确认挤出温度无误（即材料的正确挤出温度）的情况下，出现挤出电机卡顿，出料不顺畅，则尝试逆时针旋转旋钮，
每次调节一个刻度，调节完需等待1-2分钟再次挤出材料，直至挤出无卡顿即可。
旋钮开关调节的是此风扇的风量
