You can, but you won’t be able to configure the board, every value will have it’s default value.

Just don’t insert a SD card into the board.

I tried it, but when smoothieboard booting LED4 not flashing and LCD nothing displayed

LED4 is normal, it just means the board knows there is no SD card.

For the LCD, it’s normal too : the LCD is configured in the config file on the SD card, so without a SD card it can’t know there is a panel.

But, when i bought new smoothieboard, it no sd card, however, it work normally!

Yes you can use Smoothieboard to control your printer without a SD card, but it requires changing the source code and compiling ( like with all the other boards that have no native SD card configuration support ).

Why did you not get a SD card ? Where did you buy your board from exactly ?

Is there some advantage to not using the SD card or do you want to use it for something else?

Hi jlmccuan
thanks your reply.

I want to flash firmware via usb instead of copy to sdcard.
because, if use sdcard, sometimes user delete some file such as firmware.cur, config, etc. Then board will not use.

I’m pretty certain there is no EEPROM to flash on the Smoothieboard.
