This repository contains a Python 3 script that takes a text file as input and generates a 2D G-code file as output. The alphabet contained in the ascii_gcode subfolder supports all ASCII characters and is used by default, producing letters made up of just single lines, like you can see in the image below. The parameters that you can tune are the directory in which to look for the G-code alphabet, the maximum length of a line, the distance between two subsequent lines and the empty space between characters. You can then use the produced G-code in a 2D plotter, you may find this other project of mine useful: plotter.
Obtained with http://jherrm.com/gcode-viewer/
You can run the script normally with Python 3:
python3 text_to_gcode.py ARGUMENTS...
This is the help screen with all valid arguments (obtainable with python3 text_to_gcode.py --help):
usage: text_to_gcode.py [-h] [-i FILE] -o FILE [-g DIR] -l LINE_LENGTH [-s LINE_SPACING] [-p PADDING]
Compiles text into 2D gcode for plotters
optional arguments:
-h, --help show this help message and exit
-i FILE, --input FILE
File to read characters from
-o FILE, --output FILE
File in which to save the gcode result
-g DIR, --gcode-directory DIR
Directory containing the gcode information for all used characters
-l LINE_LENGTH, --line-length LINE_LENGTH
Maximum length of a line
-s LINE_SPACING, --line-spacing LINE_SPACING
Distance between two subsequent lines
-p PADDING, --padding PADDING
Empty space between characters
The required parameters are the input, the output and the line length (in order to tune this last parameter, note that the average width of a character is ~4.5).
An example of command is:
python3 --input input.txt --output output.nc --line-length 300 --line-spacing 10 --padding 3
