4. Configuration (Linux)

Included in extras are some example scripts (the scripts that I use with my Adafruit DC & Stepper Motor Hat).

Note: Scripts need to have execute privileges (chmod +x). A first line with #! is recommended.

Each .sh file is a wrapper for the .py file of the same name. The .sh file has some additional "debugging" output. The configuration page shows the following command for M106:

/home/pi/fan2.sh

which is the "log everything debug version". This could be replaced by:

python /home/pi/fan2.py

The plugin will parse the GCode M106 command and append the S value to the command line (i.e. "M106 S255" will cause the above command to be executed with " 255" appended to the end of the line).

The following table gives a short description of each of the provided examples. Each file has a .sh and a .py version where the .sh is just a wrapper for the .py file with additional debugging.

Filename	Description
fan	script to control one fan
fanoff	script to turn off one fan
fan2	script to control two fans
fanoff	script to turn off two fans

The file fanspeedtest.gcode is a test print containing just fan commands and delays. The file fanspeedquick.gcode is a shorter version of the test print.
