Hello! In this article, you are going to read about the different scroll settings in Cura. We'll explore options like retraction, combed mode, and other key settings to enhance your prints. Let's get started!<\/p>\n\n\n\n

enable retraction<\/h2>\n\n\n\n

Retraction is a technique used in 3D printing to reduce unwanted dripping or marking of material during travel movements. <\/p>\n\n\n\n

By enabling retraction in Cura, the filament is retracted or pulled back into the extruder when it is not being extruded, thus preventing dripping and improving print quality.<\/p>\n\n\n\n

Retracts the filament when the nozzle travels over an unprinted area<\/strong><\/p>\n\n\n\n

Retraction consists of retracting the filament when the nozzle moves over an unprinted area. The use of this technique is important as it avoids the formation of threads and, consequently, results in a cleaner and higher quality model.<\/p>\n\n\n\n

On the other hand, in some flexible materials or in models that require many retractions, the retraction can cause wear or "bite" of the filament.<\/p>\n\n\n\n

Shrinkage on change of layer<\/h2>\n\n\n\n

In the hover settings, you can also set the retraction on layer change. This option allows you to activate the retraction at each layer change during printing.<\/p>\n\n\n\n

The filament retracts before the nozzle begins to print the next layer, allowing for a smoother transition between layers.<\/p>\n\n\n\n

retraction distance<\/h2>\n\n\n\n

Retraction distance refers to the amount of filament that is retracted into the extruder during the travel motion.<\/p>\n\n\n\n

It is the distance in millimeters that the material retracts from the nozzle. <\/p>\n\n\n\n

A long retraction creates more tension, takes time, and decreases material oozing. On the other hand, a short shrinkage is more likely to ooze, but the material is safe and the time is shorter. It is important to correctly adjust these settings to get the best results.<\/p>\n\n\n\n

If you're just starting out, use Cura's default "retract distance" values (for an Ender 3 printer = 5.0mm<\/strong>)<\/p>\n\n\n\n

For 3D printers with a Bowden system (where the extruder is separated from the nozzle), a retraction distance of around 5-7mm is recommended. <\/p>\n\n\n\n

For printers with a direct extrusion system, the recommended retraction distance is usually lower, around 1-3mm.<\/p>\n\n\n\n

retraction speed<\/h2>\n\n\n\n

The retraction speed determines how quickly the filament retracts into the extruder. <\/p>\n\n\n\n

Too high a speed can cause problems such as jams or even damage the filament causing material wear. <\/p>\n\n\n\n

On the other hand, a slow retraction has a higher chance of dripping, but protects the material.<\/p>\n\n\n\n

If you're just starting out, use Cura's default "Retract Speed" values (for an Ender 3 printer = 45.0mm\/s<\/strong>)<\/p>\n\n\n\n

In general, a retraction speed of around 40-60mm\/s is recommended for Bowden printers and 20-40mm\/s for direct extrusion printers. <\/p>\n\n\n\n

Adjust this setting based on your specific printer and filament for best results.<\/p>\n\n\n\n

Amount of Retraction Extra Prime<\/h2>\n\n\n\n

Some filaments can ooze out during the movement of a displacement, which means that after a retraction, when you move the nozzle from one point to another, you can eject and therefore "lose" the plastic in the nozzle. <\/p>\n\n\n\n

Extra prime is the amount of extra material that is extruded after a retraction. <\/p>\n\n\n\n

This helps to make up for any empty space that may have been left in the nozzle after retraction. This setting is to compensate for the loss of molten plastic after a move.<\/p>\n\n\n\n

By default for an Ender 3 the default setting is 0.0mm3<\/sup><\/sub><\/p>\n\n\n\n

Minimum retraction displacement<\/h2>\n\n\n\n

The minimum retract travel is the distance the extruder must travel before retract is activated. <\/p>\n\n\n\n

This setting prevents unnecessary retractions for short movements, which could negatively affect print quality.<\/p>\n\n\n\n

This is the minimum amount of travel the print nozzle must travel before retraction begins.<\/p>\n\n\n\n

This setting determines the minimum distance. The value should not be set too high, as this could cause unsightly "smears" on the print.<\/p>\n\n\n\n

For an Ender 3 the default setting is 1.5mm<\/p>\n\n\n\n

Max retraction count<\/h2>\n\n\n\n

The maximum retraction count sets the maximum number of retractions that will be performed during a print. <\/p>\n\n\n\n

If the maximum retraction count is reached before the print is complete, no further retractions will be performed.<\/p>\n\n\n\n

This setting sets the maximum number of retractions in a given filament length. Retractions that exceed this value will be ignored.<\/p>\n\n\n\n

This can be useful to avoid excessive print times.<\/p>\n\n\n\n

Minimum extrusion distance window<\/h2>\n\n\n\n

The minimum extrusion distance window is a setting that prevents retraction when the distance between extrusion moves is less than the set value. <\/p>\n\n\n\n

This can be useful to avoid unnecessary retraction in small areas of the print where dripping is not a problem.<\/p>\n\n\n

Example: If the Max Retraction Count is 25 and the Minimum Extrusion Distance Window is 1.0mm, a maximum of 25 retractions will be made per 1.0mm extruded filament.<\/p>\n\n\n\n

It is the amount of filament on which the maximum retraction count is made. <\/p>\n\n\n\n

This value should be the same as the retraction distance, which limits the number of times a retraction is applied to the same section of filament.<\/p>\n\n\n\n

For an Ender 3 the default setting is 10.0mm<\/p>\n\n\n\n

hairstyle mode<\/h2>\n\n\n\n

Combed mode is a setting in Cura that allows the nozzle to move over the print without extruding material, thus avoiding possible marks or threads on the surface.<\/p>\n\n\n\n

This results in greater travel distances, but with less need for material retraction.<\/p>\n\n\n\n

Reduces the possibility of defects on the outer surfaces of the print (Threads), by staying within the perimeter of the print. <\/p>\n\n\n\n

If combing is off, the filament will retract and the print head will move straight to the next point.<\/p>\n\n\n

\n
\"Scroll
Scroll Settings \u2013 Combed Mode<\/figcaption><\/figure>\n<\/div>\n\n\n

The activated hairstyle (left) has scroll strokes not retracted within the bounds of the print.<\/p>\n\n\n\n

<\/a>The disabled hairstyle (right) has retracted the scroll movements and moves outside the bounds of the print. <\/p>\n\n\n\n

Let's see the options available in hairstyle mode:<\/strong><\/p>\n\n\n\n

Off<\/h3>\n\n\n\n

In \u201cOff\u201d combing mode, no combing movement will be performed. This can result in the appearance of small threads on the surface of the print.<\/p>\n\n\n

\n
\"Comb-off
Scroll Settings: Combed Mode \u201cOff\u201d<\/figcaption><\/figure>\n<\/div>\n\n\n

All<\/h3>\n\n\n\n

In \u201cAll\u201d combed mode, combing movements will be performed on the entire print, including the outer surface and infill. <\/p>\n\n\n\n

This can help eliminate surface stringiness, but can also increase print time.<\/p>\n\n\n

\n
\"All-over
Scroll Settings: \u201cAll\u201d Combed Mode<\/figcaption><\/figure>\n<\/div>\n\n\n

Not on the outer surface<\/h3>\n\n\n\n

In \u201cNot on Outer Surface\u201d combed mode, combing movements will be performed on all areas of the print except the outer surface. This helps keep the outer surface as clean as possible.<\/p>\n\n\n

not in the lining<\/h3>\n\n\n\n

In \u201cNot on Liner\u201d combed mode, combing movements will be performed on all areas of the print except the lining. <\/p>\n\n\n\n

The cured liner is the outer wall of the print and combed mode can improve print quality by preventing stringing.<\/p>\n\n\n

\n

About the filling<\/h3>\n\n\n\n

In \u201cOver Fill\u201d combed mode, combing movements will be performed only over the print fill. <\/p>\n\n\n\n

This can help remove strings in the padding, but leaves the outer surface without combing movement<\/strong>.<\/p>\n\n\n

In general, the best option in combed mode depends on your preferences and the type of printing you are doing. <\/p>\n\n\n\n

If the appearance of the outer surface is crucial, you can choose the "Not on outer surface" combed mode. <\/p>\n\n\n\n

If you don't care about threads and want to minimize print times, you can opt for the "Off" combed mode. <\/p>\n\n\n\n

Experiment with different options to find the configuration that best suits your needs.<\/p>\n\n\n\n

Maximum combing distance without retraction<\/h2>\n\n\n\n

Max Comb Distance Without Retraction sets the maximum distance the nozzle can travel over the print without retracting. <\/p>\n\n\n\n

It is important to balance this setting, as too large a distance can result in stringing or marking, while too small a distance can cause excessive retractions. <\/p>\n\n\n\n

Adjust this setting according to your needs and the geometry of your print.<\/p>\n\n\n\n

Retraction before the outer wall<\/h2>\n\n\n\n

Shrink before outer wall is a setting that allows you to perform a shrink before printing the outer wall of a part. <\/p>\n\n\n\n

This can help improve the quality of the outer surface by preventing potential marks or threads. <\/p>\n\n\n\n

Adjust this setting according to your needs and preferences.<\/p>\n\n\n\n

Avoid printed parts when scrolling<\/h2>\n\n\n\n

The \u201cAvoid printed parts when moving\u201d option in Cura allows the software to plan moving paths that avoid already printed areas of the part. This can help to avoid collisions or damage to already printed parts during travel movements.<\/p>\n\n\n\n

By enabling this setting, the printhead will avoid printed parts when traveling. <\/p>\n\n\n\n

To use this setting you must enable hairstyle mode.<\/p>\n\n\n

\n
\"Avoid

<\/a>The nozzle trips in both images start and end at the same location. <\/p>\n\n\n\n

Distance to avoid when scrolling<\/h2>\n\n\n\n

This setting defines the distance (in mm) between the nozzle and the print when the Avoid parts already printed option is enabled. <\/p>\n\n\n\n

The distance to avoid when traversing is a setting that sets the minimum distance between the extruder and the printed parts while traversing.<\/p>\n\n\n\n

Start of XY layer<\/h2>\n\n\n\n

The "Layer Start X" and "Layer Start Y" settings allow you to set the starting position of each layer in your print. This can be useful to optimize the positioning of the print on the platform or to avoid problem areas.<\/p>\n\n\n\n

This setting defines the coordinates to start the next layer.<\/p>\n\n\n\n

Z jump on retraction<\/h2>\n\n\n\n

Z-jump on retraction is a setting that allows the extruder to make a quick move in the Z (vertical) axis when performing a retraction.<\/p>\n\n\n\n

This helps prevent the filament from sticking to the part during retraction, especially in critical areas like edges.<\/p>\n\n\n\n

Note that for prints with a lot of retractions\/shift movements, this can increase print time.<\/p>\n\n\n
