generative svg and details converting to gcode for use on modified 3d printer.

Plotter Playground

The purpose of this project is to streamline and document the process of converting vector line art to be printed on a modded Ender 3 printer.

Artwork generation

this repo contains a app that can be used to generate SVGs from sets of points using the brilliant canvas-sketch and various resources online.

some code taken from resouces online, with some added extras.

running

• yarn install
• yarn start
• ctrl-s in browser to export.

Printing artwork.

• generate svg line to svg with this tool
• change svg width and height units to mm
• convert to gcode with svg2gcode / github. see below for settings, adjust the feedrate based on image / amount of detail. Have previously tried InkScape for this but produces too many artifacts with more compicated SVGs. with built in gcode tools
• print! I have been uploading to octoprint but this should work with sd card.
• the printer will auto home, move to the front left corner of your build surface and wait for a user input, load the pen now and resume!
