I wondered how to fix this problem, so I researched exactly how to fix a 3D printer that stopped extruding consistently and got some answers that Ill share with you. A wire brush works equally well. Sold by Taulman as PCTPE rather than TPA, PCTPE is capable of large impacts and very high tensile forces without breaking, and is a strong and flexible filament owing to its combination with Nylon. One of the first signs of a faulty PTFE tube are under-extrusion or filament noises inside the extruder. The machine would keep going, but there would be no filament. On budget printers, plastic-made extruders tend to have a shorter shelf life than metal extruders, so we recommend the latter if your budget can stretch that far. It should rise at least 3 deg per second. Id also try increasing your Retraction Extra Prime Amount to a value around 0.5 0.8mm. In some occasions when pulling out filament when hot, a small piece of filament could stay behind between the extruder drivewheel and the hot-end. Though its not impossible to do, its more challenging. A poor quality filament and involuntary contaminants lurking inside the material can accumulate and clog directly inside the nozzle at random intervals. Dirt can also cause the filament to jam and clog in the PTFE tubing. For a heated bed, it can be optional for filaments like TPU, though we highly recommend using one for better layer adhesion. The best way to fix a 3D printer that is extruding inconsistently from the nozzle is to clear any clogs or jams in the extrusion system, whether thats in the extruder gears, Bowden tube or nozzle.

Hi gents, old thread I know but my first visit so bear with me On the interface of the Ender 3, navigate to the Prepare, Move Axis, and Extruder menus, respectively. I even stuck a heat sink onto the processor and placed a fan over it. If the filament is not loaded into the extruder, yet the printer is trying to pull the filament inside. When using PLA plastic, the optimum extrusion temperature can range from as low as 180C up to 220C. A clogged extruder is often a huge headache for many users and even more so when we need to print something as soon as possible. Most common causes of overheating. For flexible filaments on Bowden machines, its not recommended to go faster than 20mm/sec. First try a "cold pull". Check your delring bearing wheel in the feeder is turning round and not in a groove - I have replaced mine with a metal bearing (2) on ebay), Check the filament is smaller than 3mm (2.85) and moving through the bowden ok, So in conclusion it could be at the hot end which is blocked in the tip, or the cool zone or the bowden, or in the feeder not driving it from the back end, or bad filament. For direct extrusion systems you should use anywhere from 0.5mm-1.0mm, for bowden systems you might want to go up to 2mm. Also make sure the bed is still flat within tolerances. Eliminate all of the plastic inside and outside of the nozzle. During the regular and normal use of a 3D printer, there is a wide variety of problems that can appear. The procedure to follow is rather simple: If the needle method didnt work, try the cold pull. Retraction beyond 2mm is likely to cause issues. The causes for extrusion failure are listed in below categories from most common to least common. Filament attracts a lot of dust, which can potentially all come into the hot-end. Then I would take the nozzle off and push out the plastic from the hot end. As we mentioned above, bad factory practices can result in a high probability of issues arising during a print. This problem arises due to a combination of natural nozzle wear and tear, poor quality filament, too high print temperature, or damage to components like the PTFE tube and extruder.
