Ender 3 Extruder Skipping Or Clicking: How To Fix It Fast
You can also run levelling print tests which are quick prints that show any levelling issues so you know if your extrusion is good enough or not. Instead of always manually levelling your bed, you can let your 3D printer do the work for you, by implementing the popular BLTouch Auto-Bed Leveling Sensor from Amazon, which saves a bunch of time and frustration in setting up your 3D printer.
It works on any bed material and several users have described a significant increase in overall print quality and reliability. Being able to trust that your 3D printer is level every time gives you a genuine feeling of confidence in your machine, that is worth every penny.
When the clicking happens in layers past the first few extruded layers, it means your extrusion temperature is too low. The reason this works is because in some cases, higher printer speeds works fine going at simple angles like a straight line, but when it comes to sharp turns and different degrees, your printer can have trouble extruding accurately at higher speeds.
Getting a higher quality extruder can definitely help out in this regard. Now you can either get the genuine Bontech, or the BondTech clone, you check the price difference and decide which to go for. If you experience your extruder clicking on infill, it could be to do with the print speed, as well as the nozzle temperature needing an increase. Many times, your printer will give you this clicking noise when your nozzle is blocked.
When your nozzle is blocked up, the extrusion and pressure builds up which sets off your extruder to start slipping. This can happen because of a variety of reasons. For example, the nozzle is damaged, dirty, blocked, etc. In other cases, the nozzle might be fine and the issue might be with the PTFE tube.
Old filament, dust, cleaning solution, and even the random insect can block your nozzle. Physical blockages are usually easy to clean. Here, you want to heat your extruder up and then use heat-resistant gloves such as kitchen gloves or a potholder to wipe the nozzle and edges down.
Then, let it cool. Take the nozzle out and use a pipe cleaner and hot water to clean the inside. From there, let it dry and put it back.
However, the plastic feeder assembly that comes with the Ender 3 is easily replaceable. You can upgrade to an MK8 in aluminum if you want to reduce future maintenance. Bowden tubes can fail. If yours is old, damaged, or clogged, you want to replace it.
Ender 3 printers are compatible with any 1. Of course, you can also try to clean your PFTE tube out with a pipe cleaner or with cold pulling.
However, most likely, the issue is caused by poorly melted filament that got stuck inside. And that can be quite difficult to do. In addition, Bowden couplings, or the couplings holding the tube to the extruder and the hot end can fail as well. However, it may be difficult to fix this issue. For example, the most common issue is that the gear is just worn down. Here, the extruder will turn the hob bolt but instead of pushing the filament through, it will grind the filament.
That can happen relatively quickly with machines like the Ender 3, because both the 3 and the Pro have just a single brass gear and a pulley. Brass is relatively soft, so it can damage with heavy use. The fastest real fix is to replace the gear. You can also choose to replace it with a steel gear , such as the steel CR from Creality. This ensures better longevity moving forward.
While this is happening, your extruder and gears will be biting down on your filament which, over time, can leave dust and debris within these parts. Make sure you are not breathing in the dust though. The most effective solution here would be taking it apart and giving it a thorough wipe down to make sure you get the offending dust and debris trapped inside.
The type and quality of your filament could also affect this, so try out a few different filament brands and see which one works best for you. This issue happened to a Prusa MK3S user and it resulted in a clicking as well as the idler gear slipping. It would cause under-extrusion and be responsible for many failed prints, but he came up with a great solution. The idle gear axle should snap firmly into place and still leave the gear free to move as it was intended.
If you experience this issue, you could also experience this clicking noise in the printing process. Check that your power cable is strong enough to handle your printer and has the correct voltage to give proper power. High spring tension can grind away at your material, leaving a deformed shape and slower movement. This can result in a clicking noise, as detailed previously.

Verified Purchase. Good choice. Same size as the original on my extruder so I didn't have to mess with resetting the e-steps. Well built and like the 2 set screws to keep things locked up. Was starting to have trouble with the extruder skipping. Replaced the stock brass gear with one of these and problem solved.
Can't really speak to the durability as I've just started a print with the new one, but the improvement in extrusion was immediate.
