Note: This is a different setting than the Z-seam. The setting is normally set to the far-right corner because that is where the Ultimaker 3's switching bay is located.

This setting defines the position closest to these coordinates to start the next layer. A greater avoid distance means a reduced chance of contact with the printed model, however a large avoid distance will significantly affect the length of the travel moves, impacting the print time, and chance of oozing. This setting defines the distance (in mm) between the nozzle and the print when avoid already printed parts is enabled. Avoid printed parts is disabled for the model on the left, and enabled for the model on the right. The travel moves in both images start and end at the exact same location. To use this setting, you must first enable combing. This decreases the possibility of coming into contact with parts of the model that have already been printed, in turn reducing the chance of surface defects or material mixing. When the shortest route from one point to another in the print is obstructed, the print head will move around it. Avoid printed partsīy enabling this setting, the print head will avoid printed parts when traveling. Combing enabled (right) has unretracted travel moves within the print’s boundaries. If combing is disabled, the material will retract and the print head will move in a straight line to the next point.Ĭombing disabled (left) has retracted travel moves that move outside the print’s boundaries. This results in greater travel distances, but with a reduced need for material retraction. Combing ModeĬombing will reduce the chance of defects on outer surfaces of the print by recalculating all nozzle travel moves to stay within the perimeter of the print. This value protects the number of retractions on the same piece of filament.įor example: If you set the maximum retraction count to 25 and the minimum extrusion distance window to 1.0 mm, it will do a maximum of 25 retractions per 1.0 mm extruded filament. This is the length of filament over which the maximum retraction count is enforced. a voronoi print), this can lead to stringing if the value is too low.Ĭross section of the feeder Minimum extrusion distance window However, for models with a lot of holes (e.g. The benefit of maximizing the amount of retractions is that it decreases the possibility of grinding. All retractions above this value will be ignored. The maximum retraction count sets the maximum number of retractions on a certain length of filament (see minimum extrusion distance window). The right model is not allowed to retract (in blue) the short distance between the railing bars due to a minimum travel restriction that is greater than the actual distance Maximum retraction count This close up of a tiny fence shows retractions (in purple) on the left model. However, the value must not be set too high as this might lead to stringing and cause ugly “blobs” to form on the print. With retraction-intensive models, you could increase the value, which decreases the number of retractions and reduces the possibility of grinding. This setting determines the minimum distance the print head must travel before a retraction move is initiated. By increasing the retraction extra prime amount, more pressure is added which helps compensate for the material. This setting can be useful, especially with flexible filaments as these require extra pressure to print properly.

This is the extra amount of material that is extruded after a retraction to compensate for oozed material after a travel move.

A low-speed retraction has an increased chance of oozing, but will protect the material. A high-speed retraction minimizes oozing, but can cause material grinding. This refers to the speed, in millimeters per second, at which the material is retracted and primed. A short retraction has an increased chance of oozing, but keeps the material secure and print time shorter. A long retraction creates more stress on the material, takes time and minimizes oozing. This is the distance in millimeters that the material is retracted from the nozzle. This setting forces the printer to retract the filament before it starts printing the next layer. Exercise caution when using flexible materials or models that require a lot of retractions as it may lead to grinding of the filament. By using retraction, “stringing” (thin threads of plastic in between the printed parts) is prevented, resulting in a much cleaner model. Without retraction, extruded material will hang between the parts. Retraction is used at the places in a print where the printer has to do a travel move between two printed parts.
