Introduction to Changing Travel Path in Cura

Cura is a popular slicing software used for 3D printing. It allows users to prepare their 3D models for printing by converting them into a format that can be understood by the 3D printer. One of the features that Cura offers is the ability to change the travel path, which can be helpful in reducing stringing and improving the overall print quality.

The travel path refers to the movement of the 3D printer's nozzle between different parts of the print. During the printing process, the nozzle needs to move from one area to another to print different sections or layers of the model. The travel path can have a significant impact on the print quality, especially when it comes to stringing or oozing of filament between different print areas.

Changing the travel path can help to reduce stringing and oozing by optimizing the movement of the nozzle. By carefully planning the travel paths, you can minimize the distance traveled by the nozzle when moving between different parts of the print. This can reduce the chances of filament oozing or stringing, resulting in cleaner and more accurate prints.

To change the travel path in Cura, follow these steps:

• Open Cura and load your 3D model.

Tips and Tricks for Adjusting Travel Path in Cura

Cura is a popular slicing software used for 3D printing. It allows users to prepare their 3D models for printing by generating the necessary instructions for the printer. One important aspect of 3D printing is the travel path, which refers to the movement of the printer head between different parts of the model during the printing process.

By default, Cura automatically calculates the travel path based on the shortest distance between two points on the model. However, there are situations where you may want to manually adjust the travel path to optimize printing time, reduce the risk of filament dragging, or improve the overall print quality. In this article, we will discuss some useful tips and tricks for adjusting the travel path in Cura.

Enable "Avoid Printed Parts" Option:

One common issue in 3D printing is the filament dragging or oozing across parts of the model that have already been printed. To avoid this, you can enable the "Avoid Printed Parts" option in Cura. This option ensures that the travel path avoids touching any printed parts, minimizing the chance of filament dragging.

Adjust the Minimum Travel Distance:

By default, Cura tries to minimize the travel distance between different parts of the model. However, you can manually adjust the minimum travel distance to optimize the printing time. Increasing the minimum travel distance can reduce the number of unnecessary movements, resulting in a faster print. On the other hand, decreasing the minimum travel distance can improve the print quality by reducing the risk of filament oozing.

Use the "Combing" Feature:

The "Combing" feature in Cura allows the printer head to move within the already printed areas instead of performing a travel move. This helps to reduce the number of retractions and improve the overall print quality. By enabling the "Not in Skin" option in the combing settings, the printer head will only move within the inner walls of the model, further minimizing the risk of visible travel lines.

Enable "Z Hop" Option:

To further prevent the nozzle from dragging across the printed parts, you can enable the "Z Hop" option in Cura. This option lifts the printer head slightly during travel moves, ensuring that it doesn't touch any printed surfaces. However, it's important to note that enabling this option may increase the printing time and potentially introduce more stringing.

Adjust Printing Speed:

Another way to optimize the travel path is by adjusting the printing speed. Slower printing speeds can give the printer head more time to move between different parts of the model, reducing the risk of filament dragging. Experiment with different printing speeds to find the optimal balance between print quality and speed.

In conclusion, adjusting the travel path in Cura can greatly improve the overall print quality and reduce the risk of filament dragging. By enabling features like "Avoid Printed Parts," adjusting the minimum travel distance, using the "Combing" feature, enabling "Z Hop," and adjusting the printing speed, you can optimize the travel path to suit your specific needs. Experimentation and fine-tuning may be necessary to find the best settings for your printer and model.
