@apple_user_1770681524 To address this, we recommend reformatting the SD card to FAT32 with a cluster size of 4096KB. This will help ensure optimal compatibility and resolve any potential file system issues. We have prepared a tutorial video to assist you with the reformatting process, which can be accessed at the following link:

@Aaron-Stewart Thank you for your understanding. Due to the Plus model’s high-bandwidth design and its modular, easy-to-replace structure, the nozzle is not designed to be replaced separately. In this case, we kindly recommend replacing the entire hotend assembly directly, which will ensure optimal performance and reliability.
