It is necessary to determine the serial port connected to the
micro-controller. For micro-controllers that connect via USB, run the
following:
```

It's common for each printer to have its own unique serial port name.
This unique name will be used when flashing the micro-controller. It's
possible there may be multiple lines in the above output - if so,
choose the line corresponding to the micro-controller (see the
[FAQ](FAQ.md#wheres-my-serial-port) for more information).
For common micro-controllers, the code can be flashed with something
similar to:
```
sudo service klipper stop
make flash FLASH_DEVICE=/dev/ttyACM0
make flash FLASH_DEVICE=/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0
sudo service klipper start
```
Be sure to update the FLASH_DEVICE with the printer's unique serial
port name.
When flashing for the first time, make sure that OctoPrint is not
connected directly to the printer (from the OctoPrint web page, under
the "Connection" section, click "Disconnect"). The most common
communication device is **/dev/ttyACM0** - see the

Make sure to review and update each setting that is appropriate for
the hardware.
It's common for each printer to have its own unique name for the
micro-controller. The name may change after flashing Klipper, so rerun
the `ls /dev/serial/by-id/*` command and then update the config file
with the unique name. For example, update the `[mcu]` section to look
something similar to:
```
[mcu]
serial: /dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0
```
After creating and editing the file it will be necessary to issue a
"restart" command in the OctoPrint web terminal to load the config. A
"status" command will report the printer is ready if the Klipper
