Obico for RepRapFirmware

If running Duet Software Framework (SBC) then version 3.5-beta4 or greater is required

This is a RepRapFirmware plugin that enables the RepRapFirmware-based 3D printers to connect to Obico.

Obico is a community-built, open-source smart 3D printing platform used by makers, enthusiasts, and tinkerers around the world.

RepRapFirmware RepRapFirmware is a comprehensive motion control firmware intended primarily for controlling 3D printers, but with applications in laser engraving/cutting and CNC too

Speical Note

While this plugin runs on a Raspberry Pi it does not require Duet Software Framework (SBC Mode) to function. You can set this up on a pi and point to the standalone printers IP address in the configuration.

Installation

cd ~
git clone https://github.com/sindarius/reprapfirmware-obico.git
cd reprapfirmware-obico
./install.sh

If you get a virtualenv error do the following

1) Install virtualenv

Installation of Crowsnest (Does not work on current DSF image_2023-04-12-DuetPi skip to uStreamer)

cd ~
git clone https://github.com/mainsail-crew/crowsnest.git
cd ~/crowsnest
sudo make install

Installation of uStreamer (Alternative to Crowsnest)

cd ~
git clone --depth=1 https://github.com/pikvm/ustreamer

---

cd ustreamer
sudo apt install libevent-dev libjpeg9-dev libbsd-dev libasound2-dev libspeex-dev libspeexdsp-dev libopus-dev

---

sudo make install

Create uStreamer user and service

sudo useradd -r ustreamer
sudo usermod -a -G video ustreamer

Modify/create ustreamer.service

sudo nano /etc/systemd/system/ustreamer.service

Copy following to ustreamer.service and save.

You may need to update /dev/video0 to match camera device
