Plugging

Cause 1: Throat

The front end of the tube is obviously black after extraction, in addition, the Teflon tube exceeds 250 degrees for printing and the filament (such as luminous) that wear nozzles will accelerate the aging plug and need to be replaced, it is recommended to use a metal hose or a special temperature-resistant print head for printing over 250 degrees .

Cause 2: Nozzle

Consumables are carbonized inside the nozzle for long-term printing, especially inferior nozzles. It is recommended to use sharp nozzles. You can try to clean or replace with clean filaments.

In addition, for printing filament with worn nozzles (such as luminous), it is recommended to use ruby or hardened steel nozzles

Cause 3: Temperature

The printing temperature is not enough, for example, ePA-CF is best to print at 280 degrees, if you use 240-250 degrees printing may block the head

Cause 4: Speed

Some materials have poor fluidity and cannot be printed at too high speed, generally 40-60mm /s is a relatively appropriate speed

Cause 5: Assembly

The nozzle is cold-tightened, causing the throat and the nozzle to not contact tightly, leaking material, and plugging. It should be heated to about 210℃ and tightened.

Cause 6: Machinery

extruder adjustment is too loose, the material bite force is not enough, so it should be properly tightened

Cause 7: Main board

The drive chip is overheated or the regulation current is too small, the extrusion motor is overheated or slips, and the current should be adjusted according to the requirements of the motor.
