This documents the reversing of the Mono 4K, which helps in writing the open-source firmware Turbo Resin.
The Anycubic Mono 4K is my first 3D printer. It's been quite a steep learning curve to print with resin, but it's really satisfying to make objects once the workflow is ironed out.
Here's the printer.
Here's an example of a printed object.
~~There are visible lines due to the lack of anti-aliasing support on the printer. Its LCD screen outputs only fully transparent, or fully opaque pixels, no gray-scale. Apparently, we have to wait for a firmware update, but I'd rather not wait.~~
Update: The original firmware handles anti-aliasing just fine.
Reverse engineering the printer will guide our implementation of a new firmware, Turbo Resin, so we can add the features that we want.
