Given that some users have received the rotary module now. I am going to pre-release the firmware for the Rotary Module here.
Snapmaker2_V1.12.0_20210318.bin
You need to upgrade the controller, touchscreen and three tool-heads. With this version of the firmware, the touchscreen will ask you to upgrade the tool-heads manually, which means that you need to upgrade them separately.
The auto-upgrading version will be released on April 1st.
Sorry for the inconvenience.
Cheers
Edwin
