This is an executable module that turns text + (ttf|otf) fonts into gcode
npm install -g text2gcode
node ./text2gcode.js --font=/path/to/text.ttf --diameter=2.5 --depth=-5 "hello world"
Options:
--font /path/to/font.ttf [required]
--depth total depth to go (may be negative) [required]
--diameter cutting tool diameter [required]
--fs size of the font in world units (mm/in) [default: 20]
--pass total depth taken off per layer (depth per pass) [default: 0.1]
--rotate rotate by % TAU (i.e. --rotate=.25 means 90 degrees) [default: 0]
--mirror mirror on the x axis [default: false]
-x translate on the x [default: 0]
-y translate on the y [default: 0]
And here's how you can generate the gcode for cutting out the npmjs logo:
note: you'll probably get better results if you use a smaller tool, but that's all I had on hand!
text2gcode --font=GUBBLO___.ttf "npm" --fs=100 --diameter=6.35 --pass=1
Which means, cut out the text "npm" (where each uppercase letter is 100mm) using a tool that is 6.35mm in diameter.
--pass ensures that there will be 5 passes total (1mm per pass!)
The result looks something like this:
