Hi, thank you for your support. To use CHITUBOX Pro, your computer and 3D printer need to satisfy the minimum system and printer firmware requirements listed on the CHITUBOX Download download page. https://www.chitubox.com/en/download/chitubox-pro Phrozen Official plans to release the new firmware this week, please be patient. At that time, you can download it from the Chitubox official website. Have a nice day :)
New firmware for Mighty 4K link: https://fis.cbd-3d.com/chitubox/chitubox/public/cms/article/Mighty_4K_P3_update_20210712.rar How to update firmware link: https://www.chitubox.com/en/article/support/howto/chitubox-pro/install-activate/how-to-update-your-printer-firmware I could not update my printer following the guidelines of Chitubox by inserting the USB and turn on the power for automatic update. I did it reversely. Turn on the printer, and then insert the USB. Open the file like you print a model. Click on the file name "update.TWP". It worked flawlessly.
You can easily find it in the Minimum Supported Firmware Versions in Chitubox Basic download page. https://fis.cbd-3d.com/chitubox/chitubox/public/cms/article/Sonic_Mini_4K_EN_Update_20210712.rar Remember to turn on the printer, and then insert the USB. Open the file like you print a model. Click on the file name "update.TWP". Automatic update did not work in my case.
