Hi, It is recommended that you update the printer firmware. If it is a .ctb file cut out by Chitubox Pro, the printer needs to update the firmware to read and print. Phrozen Official plans to launch the new firmware in this week, please be patient. You can download the new firmware from the Phrozen official website at that time. BTW, would you mind sending me your System ID, please? We will check the reason why it can't be used for less than 7 days. Thank you!
