1. Check the nozzle high temperature cotton

2. Clean up the consumable glue

3. Check whether the circuit is loose

4. Please contact the manufacturer for mainboard problems

There is a temperature fluctuation in the nozzle and hot bed of the machine. The temperature fluctuation is in a relatively small range, generally about 3 degrees plus or minus. This range is normal. If the temperature fluctuation of your machine is more than 10 degrees or even higher, it is very likely that it is a hardware problem, such as the problem of thermal sensitivity. A customer did not do a good job in leveling during the printing process, Then the printing consumables stick to the nozzle, but they are not cleaned up, which causes the consumables to squeeze the thermal sensitivity, and makes the thermal contact bad. The temperature will be normal for a while, but it can be replaced by a thermal sensitive, so the consumables glue on the nozzle must be cleaned up, otherwise it will cause the normal use of the machine.

Thermal insulation cotton aging, the machine used for a long time, each component will slowly have an aging process, such as thermal insulation cotton, heating pipe, if it is in the new machine, the role of thermal insulation cotton may not be very obvious, but after a long time may be able to play a certain role. Insulation cotton will play a very important role in insulation, it can better prevent the loss of temperature.

Motherboard factor. As mentioned above, there will be an aging process when the machine is used for a long time, and there will also be motherboards. If all conditions are good, you can check the motherboard. If it is a problem with the motherboard, you need to replace one of the components on the motherboard to solve it.
