This guide covers the frequently reported complaints of Creality Ender 3 users and lists the most effective solutions for each problem. The Creality Ender 3 is a fan-favorite 3D printer that retails far below the expected price for printers of this caliber. Owing to its low price and higher end features, a lot of beginner hobbyists buy the Ender 3 as their first 3D printer. Under-extrusion is by far the most common problem faced by Ender 3 users. You can identify an under-extrusion problem by evaluating your test prints. Flow rate is an essential aspect of print quality that is easy to overlook when tuning settings for a new filament or when setting up a new printer. Decreasing the print speed will ensure that the filament is laid evenly and has sufficient time to set before the next portion of the print is deposited on the build surface. Have a quick test print ready because you will likely have to print a few until you find the optimal settings for your printer. Adjusting the Z-distance, which is the vertical distance from the nozzle to the print bed, can typically improve layer uniformity and setting. You can typically identify a poor Z-distance setting by a thin first layer. If you are still having problems, follow our more comprehensive bed leveling guide to cover any nozzle or bed alignment issue that could be affecting your print quality. Though this is unlikely to be an issue for brand-new machines, if you have used your Ender 3 printer several times without problems and are suddenly facing extrusion problems, it is very likely that a clogged nozzle is to blame. Run a short test print and carefully watch the filament as it is extruded.

However, if you cannot see through it, then use a Q-Tip with some Isopropyl Alcohol on it and swab out any clogs or deposits that may have built up on the inside of your nozzle. We will walk through ender 3 not extruding one below and explain what settings can be used to solve the problem. It is extremely tempting to try to consume as much information about perfecting prints as much as possible, but this can lead to significant problems if you are just starting out or using a new printer, ender 3 not extruding.

If your printer was extruding properly at the beginning of your print, but suddenly stopped extruding later on, there are typically only a few things that could have caused this problem. We will explain each common cause below and provide suggestions for fixing the issue. If your printer was having trouble extruding at the very beginning of the print, please see the Not Extruding at Start of Print section. This one is pretty obvious, but before checking the other issues, first verify that you still have filament leading into the nozzle. If the spool has run out, you will need to load a new spool before continuing the print. During a print, the extruder motor is constantly spinning trying to push the filament into the nozzle so that your printer can keep extruding plastic.

We can all agree that 3D printers are complex machines, with many moving parts coming together and working seamlessly to make the magic of 3D printing possible in the comfort of our own homes. Unfortunately, as complexity increases, so does the possibility of issues occurring, as even a single part that does not work as intended can cause the entire printing process to fail and prevent the printer from operating until the appropriate solution is approved. Today, our topic is a critical issue that can entirely prevent the Ender 3 from conducting the printing process, where the printer, for unknown reasons, does not extrude any filament at all and moves the printhead around without printing anything. As there can be a few different culprits behind your Ender 3 not extruding any filament, we have listed the most common reasons below:. In the following sections, we will go into the reasons that can prevent the Ender 3 from extruding in more detail, find out what we can do to fix this issue, and take a quick look at the process of triggering a manual extrusion, which can act as a solution at times. Finding the culprit behind the issue of Ender 3 not extruding any plastic is a slightly complicated one, as there are a few different factors that can cause this problem to appear on your printer and prevent you from printing. Below, you will find the most common reasons that can prevent your Ender 3 from extruding filaments, alongside detailed descriptions that we believe will be helpful to pinpoint the problem in your case. Fixing the problem of the Ender 3 not extruding plastic is no straightforward task due to the possibility of many things causing it, but in most cases, following a checklist that involves most of the common factors that can cause such a problem does the trick.

The hot plastic inside the nozzle tends to ooze out of the tip, which creates a void inside the nozzle where the plastic has drained out. For this process, our primary recommendation would be to ensure that the heater cartridge wires are connected correctly to the mainboard without any looseness or wiggle that could lead to the connection becoming compromised by disconnecting and re-connecting them carefully, as such disconnection can easily prevent the heater cartridge from operating as intended and cause the hotend not to heat up. If the filament end is straight, the extruder could be faulty. Retraction also works when the extruder moves from one of the bed areas to another, preventing the material from leaking onto the object. It is fixed to the tube with Allen bolts, and these bolts could become loose. Inconsistent Extrusion. Add a raft or brim By increasing the surface area of the print, bed adhesion can be improved. If its end is bent, there is a chance the filament is slipping under the bearing of the extruder instead of going through it. First, try tightening the extruder arm by adjusting the screw around which the extrusion assembly pivots. Clogged Extruder. Remember, it is always best to change settings one at a time in small increments to avoid over correcting.

While it all seems so simple when it comes together, extrusion is a pretty complex operation that relies on all the distinct software and hardware components working correctly together, which causes it to have multiple points of failure where even one of the parts becoming inoperational can bring everything to a halt.

If you have checked everything else and are still having trouble, it could be a clogged nozzle or 3d printer filament not coming out of your printer with a bunch of debris attached to it. This motor support can assist in alignment without causing binding, and this shim corrects bent carriage brackets to support the stepper motor. Thermistors are tiny heating elements that control the temperature of the hotend and extrusion area based on a temperature set-point. While the more advanced users may be able to go down the route of testing the power supply voltage with a multimeter to find out whether the power supply is in good shape or not, which would point them toward the problematic component without having to replace both, the fact that this may not be an option for everyone makes replacing the components or sending your 3D printer in for a repair the go-to solution in most cases. You can then assemble the extruder and extruder fan back into their places and feed the filament again. Simply check and tighten the cog bolts to fix the issue. As noted above, take care when changing any parts in your printer if you are not getting it serviced by someone who does this professionally. Now, squeeze the extruder arm and place the filament between the toothed extruder gear and idler pulley. Add external extrusion pressure If the problem persists, try swapping out the filament and adding external pressure. Just follow the steps below. The only way to resolve this issue is to turn off the printer and allow the electronics to cool down. If your extruder motor is spinning, but the filament is not moving, then this is likely the cause. A stopgap solution is to shut down your printer and plug in its power supply. Owing to its low price and higher end features, a lot of beginner hobbyists buy the Ender 3 as their first 3D printer.
