Main benefit with this approach of G-code generation is the control over every vector of your G-code. With conventional slicers you are left with planar cross-sections of the 3D mesh and can't control the extrusion path itself. With fu

I started as a painter, discovered multi-color 3D Printing and learned basic coding skills. I'm currently working on a Blender Addon that lets you modify G-code inside of Blender. Shifting more and more to the developer side of things

When learning electronics as a hobbyist, amasci had some really nice non-textbpook explanations of voltage, current and transistors. Really made you think deeply about the subject. Here is an example about transistors. http://ama

Nano might fit the definition, but 100micron (0.1mm) is visible with an ordinary microscope, so no electron microscope needed.

Most like some postprocessing in the gcode to multiply the extrusion rate by some factor for each blob.

I wrote a G-code Importer for Blender recently. Having access to the toolpaths directly lets you do some interesting things conventional slicers can't do. https://github.com/Heinz-Loepmeier/Blender-Gcode-Import&#x

You lose half of the possible steps in RGB mode (128 instead of 256), but a change of 2 is hardly noticeable when painting, even when applied to all three channels.

Yes, there is a Gimp build that allows you to change colors via MIDI. One thing I didn't like about the built I tested was that you can't change colors while! making a stroke.

Here is quick video summary about the "Masquerade" puzzle. The solution seems quite arbitrary. (drawing a line over left eye and hand without knowing the exact point can lead to quite different letters.) https://youtu.b

another great recommendation are andrew loomis' books on drawring. very detailed and technical approach. (and they are free!) http://www.placidchaos.com/AM/index.php/2006/02/21/andrew_lo...
