As a passionate advocate for open source software, I am deeply concerned about the recent actions of Anycubic, a prominent manufacturer of 3D printers. It has come to my attention that Anycubic has been utilizing open source software in their products without adequately honoring the terms of the associated licenses. This disregard for the principles and values that underpin open source communities is not only disappointing but also detrimental to the progress and innovation fostered by such communities.

Open source software has revolutionized various industries, including 3D printing, by enabling collaboration, sharing of knowledge, and driving technological advancements. The concept behind open source is simple yet powerful: when individuals or organizations benefit from using open source software, they should contribute back to the community by sharing their modifications and improvements.

Anycubic's failure to publish their modified source code violates this fundamental principle. By withholding their modifications from public view, they deny other users access to valuable enhancements and hinder further development within the 3D printing community. This lack of transparency not only undermines trust but also stifles innovation.

To support these claims with relevant facts:

1. The Marlin firmware used in many Anycubic printers is released under an open-source license (GPLv3). According to this license's terms, any modifications made to Marlin must be made available as well.

2. Numerous reports from users indicate that Anycubic has failed to provide access to modified versions of Marlin firmware used in their printers.

By signing this petition, we urge Anycubic Technologies Co., Ltd., a leading player in the 3D printing industry, to honor its commitment towards open-source principles by promptly publishing all modified versions of Marlin firmware used in its products.

We believe that requiring Anycubic to comply with open source licenses will not only demonstrate their dedication to the principles of collaboration and innovation but also foster a stronger and more vibrant 3D printing community. Let us come together and demand that Anycubic fulfills its obligations, ensuring that the benefits of open source software are shared by all.

Sign this petition today to show your support for open source values and urge Anycubic to honor the open-source license by publishing their modified Marlin firmware. Together, we can make a difference in preserving the spirit of openness, sharing, and progress within the 3D printing community.
