I received my system in January 2019, but was unable to use it until now. It is running firmware version 2.4.
I have followed all instructions for upgrading the system using the USB, and it never works. I am using the USB that came with the system, formatted FAT32. I put the Update.bin in the root folder. When the system turns on, the blue light immediately blinks fast, and the upgrade never happens.
I also cannot access my gcode files on the same USB. I save the file with Snapmaker Luban by generating and exporting the gcode. I load the USB into the Snapmaker. When I select “files” on the touchscreen, nothing happens.
