Sometimes we may find our result deviate a lot from our expectation seemd as molten. In that situation,we may encounter a problem caused by overheating.
There are two types of possible causes for Overheating, insufficient cooling and excessive nozzle temperature.For insufficient cooling,it makes a lower cooling of filament so filament is easy to change their shape.For Excessive nozzle temperature,it makes a longer cooling time so filament is easy to change their shape.
For the problem of Insufficient cooling,we can try to use a more powerful fan.
For the problem of excessive nozzle temperature,we can set a lower temerature setting in filament page.
