6.3 Cleaning the nozzle

After a lot of printing, the nozzle may be covered with a layer of oxidized ABS.
When the printer is printing, this oxidized ABS may melt on the nozzle, and may
create discolored spots the model. To avoid this you need to regularly clean the
nozzle.
Firstly, preheat the nozzle in order to melt the oxidized ABS. Use the ―Extrude‖
button on the ―Maintain‖ dialogue box, then lower the platform to the bottom.
Lastly, use some heat-resistant material, like 100 percent cotton cloth or soft
paper. A pair of tweezers will also be required. Then clip paper or some other
heat-resistant things with tweezers to clean up the nozzle.
