Smoothieboard has a USB port.

You can plug a USB cable into the Smoothieboard, and plug that cable into your computer, and you’ll then be able to control your Smoothieboard using Software on your computer.


The USB port exposes several interfaces:

Take care

A few things to be careful of to avoid USB disconnections:

If all of those rules are applied, USB will work fine in the vast majority of cases.


If using Linux or Mac, just plug the USB cable into the computer and the Smoothieboard, and everything should work right out of the box.

If you are using Windows (older than 10) however, you need to install a driver.

You can find this driver at the following URL: Windows drivers

If you are using Windows 10, you do not need to install the driver, and installing the driver could cause trouble. For all older versions, the driver is required.


Once the driver is installed, the Smoothieboard should be recognized both as a Mass Storage Device (similar to a USB thumb drive), allowing you to access the files on the SD cards, as well as a Serial (COM) device, allowing you to send commands (for example via Pronterface).
