Using Inkscape to Generate Gcode

Gcode Plot

1. Video 1 - [1]
2. GcodePlot extension for inkscape. Inkscape post - [2]. Github - [3]. Instructable - [4]
3. Pen holder 3D design - [5]. Simplest way - is a flat piece of plastic. Support should be 2-point for parallelogramming (goes straight down) or 4 point for straight up-down - though 2-point parallelogramming should likewise produce straight up-down. See D3D Universal#Plotter pen holder design.

Instructions

From Instructable, in pertinent part, after installing extension:

1. Restart or start Inkscape.
2. Load the SVG file you want to draw or cut into Inskcape. The lower-left corner of the page in Inkscape corresponds to the minimum X and Y coordinates you measured in the previous step. Make sure your images fit into the print area.
3. Convert the drawing to a path: ctrl-A to select everything, then Path | Object to Path.
4. Save to gcode:
   1. File | Save As...
   2. Select: "3-axis gcode plotter" ... And a massive popup comes out. Should be self-explanatory, outside of:
   3. Make the area SAME in document size as the X and Y in the output settings. Straightforward.

Exercise

1. Get your hands on SVG files. Since there are more PNG than SVG available in the wild - convert PNG to SVG first with Inkscape - [6]
2. Take a file such as . But would need to convert it to vectors. Power user material.
3. So start with a vector file - File:Axis Idler LAI SVGs.zip
4. Yes! Convert Object to Path in Path menu in inskscape
5. Export gcode.
6. How do you know g-code is valid? Use OpenSCAM - see [7]. To install a deb package, use a tool called gdebi

MJ Notes

1. Installed GcodePlot for Inkscape
2. Drew in inkscape. Set coordinates the same in Save As Gcode and in Document/Settings for the document
3. Viewed the file in https://ncviewer.com/. Line I drew showed up, but not the text.
