3.0.2 Firmware for MMU3

Summary

• Information for the MK3.5 owners
• Information for the MK3S+ owners
• List of pull requests

This is the stable release of firmware version 3.0.2 for the MMU3 unit, primarily intended for the upcoming Original Prusa MK3.5. Further details are provided below.

Information for the MK3.5 owners

This is an initial release containing updates to the firmware, enabling compatibility with the MMU3 unit and the Original Prusa MK3.5.

Please note, that this 3.0.2 release must be paired with an upcoming specific firmware version for the MK3.5. Once the printer firmware is prepared, it will be published on GitHub, with further instructions on how to use the MMU3 with MK3.5.

Information for the MK3S+ owners

This firmware is primarily focused on adding support for the MK3.5. There are no changes for MK3S+ owners, therefore updating the firmware is not needed.

Nevertheless, there will be a possibility to update your unit, but please note that this 3.0.2 release must be paired with an upcoming specific firmware version for the MK3S+. Once the printer firmware is ready, it will be published on GitHub, along with additional information.
