INTRODUCTION
Most 3D models take more than a few hours to print, so
you may wish to leave the 3D printer at some point in the
prinng process. Using an Arducam camera to monitor 3D
prinng can make you pay close aenon to your creaon.
Since most cameras are not made specically for the use
of 3D prinng soware, it is impossible to obtain proper
support from the manufacturer.
Fortunately, Arducam can help you solve all installaon
and setup problems. In this manual, we will introduce the
method to use Arducam motorized focus camera modules
to monitor 3D printers, which can see much closer than
the xed focus lens.
Geng started here!

printers/
We will keep online up-to-date connuously.
1. Download and install OctoPi
If you have been accomplished OctoPi installaon and
WiFi setup, please go to the chapter on How to use the
motorized focus camera.
1.1. Download link: hps://octoprint.org/download/
SOFTWARE SETUP
It ulizes these custom commands from your slicer to
adjust focus while prinng: @ARDUCAMFOCUSSET <ABS-
FOCUS> to specify an absolute focus. This command is
handy to reset the focus when starng a new print aer a
power failure.
Example: @ARDUCAMFOCUSSET 100 will move the focus
to 100.
The enre range is 0~1023. Seng 0 corresponds to
innity, and seng 1023 corresponds to a close focal
length of about 5CM.
• Enable I2C Interface
The plugin uses I2C to communicate with the camera.
However, I2C is not enabled by default. The Arducam
Focus plugin will not funcon unl you enable I2C.

SOFTWARE SETUP
Please ssh to your Octopi and enter these commands (This
only needs to be done once):
After executing the above command, the file /
boot/config.txt should now have the commands
to enable I2C. In addition, you have to enable the
I2C kernel module using raspi-config. Again, ssh to
your octopi, and then enter this command:
Step 1. select “5 Interfacing Options”
Step 2. select “P5 I2C”
Step 3. raspi-config will ask, “Would you like the
ARM I2C interface to be enabled?”
Step 4. select “Yes”
dtparam=i2c_vc=on
if ! grep -Fxq "^#ArduCamFocus$" /boot/cong.txt; then
sudo cat << end_of_le >> /boot/cong.txt
#ArduCamFocus
dtparam=i2c_arm=on
end_of_le

sudo raspi-cong
SOFTWARE SETUP
Step 5. you should see, “The ARM I2C interface is
enabled”
Step 6. select “Finish”
After you reboot, the camera should become
operational in OctoPrint.
• Download the Plugin
Open up the Octopi login page: http://[IP]/
#control, please note that the [IP] should be
replaced with address shown in the figure below.
/home/pi/oprint/bin/pip install hps://github.com/ArduCAM/RaspberryPi/
releases/download/OctoPrint-Arducamfocus/OctoPrint-Arducamfocus.zip
wlan0: ags-4163<UP, BROADCAST,RUNNING,MULTICAST> MTU 1500
Inet 192.168.0.52 netmask 255.255.255.0 broadcast 192.168.0.255
Now you can view the Arducam Focus Control
interface and use the tab to adjust focus.
TROUBLESHOOTING
1. Failed to run camera with raspstill
The raspisll requires full access to the camera device
when it runs, which is being locked by the webcamd
service. You would have to stop the webcamd service in
order to use the raspistill. Otherwise, you will not be able
to open the camera.
