It is disappointing to again see various 3D printer companies being reluctant to release the marlin open source firmware for their products.

This continued refusal is unacceptable, as these companies have been specifically made aware of their obligations under the GPL license.

As a result, we will be removing AnyCubic and Creality3D from our “Friends of GPL” list until the open source firmware is supplied to owners.

These GPL violations have commercial consequences too – resellers such as Printed Solid, have indicated that they are no longer able to sell Creality3D due to their non-compliance. We support and applaud Printed Solid for taking a firm stand on this issue, as this negatively affects their business operations too.

The AnyCubic Chiron launch has also seen much frustration from customers, due to major bugs in the provided firmware preventing proper calibration and tuning of the machines. While poor factory firmware has been overcome for other printers thanks to the community producing new versions, these efforts are near-impossible for the Chiron unless they release the source for their modified Marlin firmware.

We encourage AnyCubic and Creality3D to consider both their obligations under the GPL, as well as the many other benefits they will receive, from releasing marlin source code for all of their printer models.
