I wrote the instructions for upgrading from Mk3 to Mk4 Pro (added OLED only) in my blog, and uploaded a simple demonstration of the Mk4 Pro on YouTube. I hope they help everyone (especially macOS users). Note that my blog is written in Japanese, so please use a translator like DeepL or Google translate.
In addition, I designed a mount for attaching 3DChameleon to a metal rack, and uploaded STLs to Printables. I would appreciate if you download and like them.
