@Sorwhitwrose1998 Hello, from your description, it seems that Tina2 was chosen in Wiibuilder.
Tina2 and Tina2S use different protocols for serial communication and WiFi communication, and incorrect printer selection may cause connection failure.
When you choose Tina2s in Wiibuilder, the software does not have the ability to upload files with serial connection, it sends the Gcode to the Tina2s line by line instead.
