#SDPremote Python app that uses an internal webserver (tornado) to serve a client to control / monitor your ultimaker / other marlin based 3d printer. Can also use mjpeg-streamer to stream and record pictures (TLs) while printing from SD-Card. It will run on Windows, Linux and on the Raspberry Pi (wheezy, jessie). It also has a pygame interface included that can be used as a touchscreen interface when you have a piTFT (or similar with 320x240 resolution attached). It does stream gcode (directly and to the SD-Card, experimental) and can monitor the printer while printing from SD-Card. The applications name is derived from SD - Card, 3D-Printing and remote. Below you can see a screenshot of the webinterface's control section where you can control and monitor your printer and one of the pygame interface.

#Installation (Raspberry Pi)

Start with a fresh install of the latest wheezy or Jessie. Expand filesystem, install piTFT drivers, touchscreen interface etc.

#install dependencies ##pygame

sudo apt-get install python-pygame

##install tornado / pyserial 2.7 (force)

sudo apt-get install python-pip
sudo pip install pyserial==2.7
sudo pip install tornado

OR if you want to install tornado and pyserial for the current user only

pip install --user pyserial==2.7
pip install --user tornado

##make sure the user "pi" (or replace with your own user) has access to the serial port

sudo usermod -a -G tty pi
sudo usermod -a -G dialout pi

If there are any issues with a non-standard baudrate, like 250000, try to patch pyserial (< 2.7) according to this guide. This should fix the connection issues. As far as I know, pyserial was patched some time ago, but until now, I could not test it on a new system.

##install mjpeg-streamer

cd ~
sudo apt-get install git subversion libjpeg8-dev imagemagick libav-tools cmake
git clone https://github.com/jacksonliam/mjpg-streamer.git
cd mjpg-streamer/mjpg-streamer-experimental
export LD_LIBRARY_PATH=.
make

make sure mjpeg-streamer is running BEFORE SDPremote starts, best to run it as a deamon (or try with screen (sudo apt-get install screen)), look at 'raspi_stream' (in the root umcam folder, after the installation), configure for your input device, make it executable and run it.

The command I Use for the raspi cam:

cd mjpg-streamer/mjpg-streamer-experimental
./mjpg_streamer -i "./input_raspicam.so -fps 30 -x 1024 -y 768 -quality 90" -o "./output_http.so -w ./www"

For any standard USB Camera try (you can experiment with the settings, but try without first):

cd mjpg-streamer/mjpg-streamer-experimental
./mjpg_streamer -i "./input_uvc.so" -o "./output_http.so -w ./www"

If it's up and running you can point your browser to http://YourPisIP:8080 and check if it's streaming. If it does, install mjpg-streamer with this command:

make install

This will install mjpg_streamer in /usr/local/bin. Now copy the provided mjpg-streamer.service to /etc/systemd/system/mjpg-streamer.service and activate the systemd startup script with the following commands:

sudo systemctl enable mjpg-streamer

After a reboot, mjpeg_streamer should be started automatically.

#install SDPremote

cd ~
git clone https://github.com/MartinBienz/SDPremote.git

##run (no (touch)screen = no pygame interface):

cd SDPremote
python main.py --headless

##run (pitft 2.8 / 320x240, touchscreen):

cd SDPremote
python main.py --fullscreen --hidemouse

##run (GPIO enabled (I check fo sudo), no pygame interface)

cd SDPremote
sudo python main.py --headless

#configuration After the application started, you can point your browser to http://yourPisIP:8081 and start configuring the application using the web / tornado interface.
