Can I modify the slicing algorithm based on the Curaengine source code？

[biexiangi]

As a graduate student, my current research direction is the secondary development of cura software and innovation in its slicing algorithm. At present, according to the source code of Cura and Curaengine, I have connected external Curaengine through Cura to conduct external debugging. However, I still don't understand the algorithm involved in the Curaengine source code, so I want to ask the feasibility of slicing algorithm innovation through two source codes, and whether I can complete my project. As a novice, I have been working hard. I hope someone can give me a simple answer. thank you

Hi @biexiangi

Innovating on the slicing algorithm used in Cura is a complex and challenging task, but it can be feasible with the right resources, dedication, and support. Here are some key points to consider:

1. Feasibility: It is feasible to work on improving the slicing algorithm in Cura if you have a good understanding of 3D printing, mathematics, and programming. However, be prepared for a steep learning curve, especially if you are new to this area. To start getting a grasp of algorithms involved in transforming a 3D model you can take a look at the Wiki in this page https://github.com/Ultimaker/CuraEngine/wiki/Pipeline

2. Resources: Ensure you have access to the necessary resources, such as a development environment, computing power, and 3D printers for testing your algorithm changes.

For setting up the development environment I suggest that you take a look at the Wiki page https://github.com/Ultimaker/Cura/wiki/Running-Cura-from-Source which will tell you how to setup the complete development environment.

When you want to connect an external CuraEngine You might want to look in the Wiki of this repo https://github.com/Ultimaker/CuraEngine/wiki/Building-CuraEngine-From-Source

3. Start Small: Begin with small improvements or optimizations to get a feel for the codebase and the challenges involved. Gradually work your way up to more significant algorithmic changes.

4. Testing and Validation: Extensively test your changes to ensure they produce reliable and high-quality prints. This may involve creating a testing framework and using various 3D models to evaluate the results.

5. Legal and Licensing: Be aware of the licensing terms and legal considerations associated with modifying and distributing open-source software like Cura.

6. Patience and Persistence: Developing and innovating in this domain can be challenging, so patience and persistence are crucial. Don't be discouraged by setbacks or difficulties.

In summary, while innovating on the slicing algorithm in Cura is a challenging endeavor, it is feasible with the right approach and dedication. Keep learning, testing, and collaborating with others in the field, and you may be able to make significant contributions to the 3D printing community. Good luck with your research project!

Thank you for your guidance and help. At present, I am proceeding according to the plan, completely according to the website you sent. The current problem: Steps through https://github.com/Ultimaker/Cura/wiki/Running-Cura-from-Source I can't use Pycharm running, now can only be opened with Windows Powershell Cura, This problem was not solved, but it did not affect the innovation of my algorithm, and I will consider solving this problem when I modify the software interface in the future. According to the external Curaengine, https://github.com/Ultimaker/CuraEngine/wiki/Building-CuraEngine-From-Source Currently in step by step debugging with Curaengine.exe, not very good basics, but working on it. I hope it works out for the best. Finally, thank you again for your reply.
