Thank you very much for all the praise. Cool to see some fellow 3dp enthusiasts here.

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 fullcontroll.xyz you can edit every point and its properties like speed, extrusion values or non-planar coords.

I've been developing a similar add-on for Blender called nozzleboss. https://github.com/Heinz-Loepmeier/nozzleboss It lets you use Blenders modeling tools to create toolpaths directly and export to G-code. It has an importer as well, that lets you edit existing G-code with Blender, e.g. using sculpt tools to deform G-code paths. https://www.youtube.com/watch?v=aoM8-Xdh9w8

Using Blender is nice here, because you have access to so much modeling tools already and don't need to code to generate G-code (though you could, Blenders python api or geometry nodes is very well suited for that). The add-on uses vertex colors to store meta information on every segment of the G-code, so you can paint on extrusion/speed multipliers or color itself very intuitively. (Different colors in FDM printing are usually done by segmentation of the mesh into different parts, which can be difficult. Though PrusaSlicer introduced multi-material painting recently, so if you are interested check that out.)

There is a tool called ‚Shut up, Windows 10‘ that let‘s you deactivate all telemetry and other annoying features with one click.

What nfts?

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, but still trying to work with both, can be a powerful combination.

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://amasci.com/amateur/transis.html

I built an interesting Bi-Polar Plotter with multi-pen capabilities this year. Really cool to look at. :) https://hackaday.io/project/177633-dual-disc-polar-printer

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. [link redacted]

I've been experimenting with storing extrusion multiplier info inside Blender to make weighted extrusion values based on a texture.

Needs an SSL update, otherwise it won't work in newer chrome versions.

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.

I changed that, because most people prefer HSB. Personally I draw in RGB mode, press 'm' to toggle modes.

I recently found this guide on the fundamentals of color management very helpful. https://hg2dc.com/

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.be/3yaHBdhIsCo The Rocky mountains treasure is also mentioned.

another great recommendation are andrew loomis' books on drawring. very detailed and technical approach. (and they are free!)
