Back in August, Creality sent us an updated debug version of the firmware, 1.0.7.
We sent this firmware to the two users, and it fixed the air assist for them.
I’m quite sure, we reported back to Creality, but obviously, they didn’t update the firmware on their website yet. (It still shows version 1.0.6 dated 2025-03-25)
I’m sending you a DM with the link to that special debug version.
If you decide to reach out to Creality, you can refer to this thread, and the one mentioned earlier:
A side note that I can’t resist mentioning: They are using modified GRBL sourcecode. Grbl is free software, released under the GPLv3 license, GPLv3 is a “copy-left” license, which means that any derivative work must be distributed under the same or equivalent license terms.
