The package does not include a standard USB flash drive. You can still initiate printing normally without a USB, as the printer has built-in storage space to run print files. However, without a USB inserted, the following functions will be affected:
1. The recording and time-lapse photography functions can't be turned on;
2. Printing cannot be initiated through the LAN;
3. Print files cannot be sent to the machine for storage through the Bambu Studio;
4. Log files cannot be exported;
USB requirements: USB2.0 protocol or above (actual minimum write speed needs to be greater than 10MB/s), supported file formats are FAT32 and exFAT. and the printer only supports mounting one USB, and cannot connect multiple USB via a USB hub.
