Retraction is concerned with pulling the filament all the way back during its travel time. If done correctly, it will take all of the pressure from the nozzle of the printer. Virtually every 3D slicer engine available today has certain settings when it comes to getting rid of 3D printing stringing. They help ensure that you will be able to get into the sweet 'no stringing' zone. This way you will be able to enjoy all of our prints with your Ender 3 machine. Moby dick whale game.
Let us study Creality's Ender 3 retraction settings with the help of the Cura slicer. It has all the relevant settings for stringing 3D printing as well as the recommended values for each filament type.

Modeling software: PROE, Solid-works, UG, 3d Max, Rhino 3D design software, etc. Operation Temperature: Max Nozzle Temperature: 255 degree Celsius Max Hot bed Temperature: 110 degree Celsius. I am new to 3d printing Simple PLA 180c to 220c test tower, Ive only used cura 4.3.0, with my Ender 3 pro.2 layer height and print standing up. (i turned sideways to display temps properly on the cad as an example) not sure how this will run on other slicers but please let me know in the comments below. Gcode for changing AtZ is set to change every 25 layers as per below. I wrote this tutorial to share my experience about how to easily make multicolor prints with a single extruder ( ender 3 ) with the highest possible quality by manually changing the filament. The keyring exaples on the pics are made in TPU following this procedure. I've uploaded a simple cube useful to test and get familiar with the procedure: Load your file in Cura and then click on. I would like the Ender 3 PRO to be added as a unique separate printer because the Ender 3 PRO is an improved version of the Ender 3 with some specs changed that would be affected by the printer definition. Describe alternatives you've considered I tried changing the ender 3 printer definition to the specs of the ender 3 pro but did not succeed. Creality Ender 3 Pro 3D Printer. Software Bundle: Slice software: Cura, Repetier-Host, Simplify3D etc. Modeling software: PROE, Solid-works, UG, 3d Max, Rhino 3D design software, etc. Operation Temperature: Max Nozzle Temperature: 255 degree Celsius Max Hot bed Temperature: 110 degree Celsius Power Requirements: Input: AC:100-120V/6.8A 200-240V/3.4A 50/60Hz Output: DC 24V 15A.
The recommended values are a good baseline and you can adjust up and down from there.
Best Retraction Settings for Ender 3
What is Retraction Travel Speed?
The retraction speed of your Ender 3 will determine precisely how fast the extruder will pull the filament out of the Bowden tube onwards through to the nozzle. This is typically in millimeters per second (mm/s). It is very simple really. The higher the overall setting, the faster will be the movement.

And that is that you will need to get all of the filament strings out of the nozzle as quickly as possible. However the faster you do so, the greater will be the potential damage to the filament and ultimately your build.
How Do You Calculate Retraction Distance?
Retracting distance may be defined as the total amount of filament that the machine's extruder will retract from its nozzle. Let us suppose the setting is set at 7 mm. Here, the extruder will be able to pull the requisite 7 mm of filament right out of the unit's Bowden tube.
How Do You Stop The Stringing On Ender 3 Pro?
Once your Ender 3 is ready and able to push down more filaments into the nozzle, it will automatically move the same amount of filament (7mm) right back into the machine's Bowden tube. This will lead to a momentary relief in pressure that can easily stop oozing and even prevent stringing.
Once the filament material is pushed back into the Bowden tube after its retraction, your printer will be prepared to print again. This whole exercise is also referred to as priming.
What Is A Good Retraction Distance?
As a general rule, it is a great idea to start off with low Cura settings such as 5 mm and only then proceed to adjust it either up or down by a maximum of 1 mm until you manage it just right. https://borcatelo1979.mystrikingly.com/blog/17-permute-3. Your goal should always be to get it down to the lowest possible number even as you substantially reduce the stringing effect.
In this case, a reasonably good range would be 3 to 7 millimeters max. If the number is too low it won't be able to have any reducing effect on stringing. Too high and it might damage your build and even increase your print time.
Extra Prime Amount
This setting will be of great help in compensating for any material that had been lost due to excessive oozing. Once your machine primes after retraction, it will automatically push the amount you have set beforehand
Maximum Retraction Count
This setting is used to adjust the total number of maximum retractions that may be possible in a specific area. Using this option will automatically protect your filament from damage by retracting and priming too many times. Since the extruder is using a gear with teeth that dig into the filament to push and pull it, the more your extruder retractions occur on one specific piece of filament, the more damage can occur.
Minimum Extrusion Distance Window
This window enables you to specify very precisely the length of filament on which you can enforce the ‘Maximum Retraction Count.' For example, if you decide to set this count to a total of 5 while the Minimum Extrusion Distance Window (MEDW) is set to 10mm: In this case, the machine's extruder will only allow a total of 5 retractions over a full 10mm piece of filament. Voice effects pc. In fact, all retraction commands will be ignored once the desired number has been reached.
Limit Support Retractions
Cura Ender 3 Profiles
This setting is available via a checkbox format. Once it is enabled, it will automatically stop all retractions whenever it is moving within its supports. It will still lead to a bit of stringing, but it will be restricted within the support structure only. You can verify it with a stringing test on various prints. Cleanmymac 3 3 9 6. Freddy frenzy 2.
