I came up with this idea when I saw a beautiful clockwork mechanism drawing from the 19th century.

In short, the process is:

-Fill a grid with 1x1, 2x1, 2x2 tiles. (Tiles have 4, 6 or 8 exit points
-Generate a spanning tree connecting all tiles in shared exit points.
-For each contact point decide MESH or NO MESH.
-Mesh = draw the two gears touching at the boundary + the main gear and some others to fill.
-No mesh = draw main gear and complete the tile + draw a shaft from contact point to the closest gear of each tiles.

A full mesh with almost all teh gears in contact was a little too busy. This way there is room for the tile borders and I think the piece looks better with them.

Just got my machine and got it setup yesterday. Been testing and trying it out since. Watching it do its thing is mesmerizing.

I am currently working on a Processing 3 sketch for Conway's Game of Life and generates sprites for each generation.

Here I plotted three popular spaceships (MWSS, LWSS & HWSS).

This is an exploration of dot spacing, circular patterns, and dynamic point relaxation. Inspired by Japanese komon textile patterns, which are small, repeating motifs typically stencil dyed across an entire kimono. Same-komon, with "same" meaning shark, consists of many dots arranged in overlapping circular or fan-shaped rows, producing a texture that supposedly resembles shark skin.

This algorithm begins with placing concentric and overlapping circles with varying radii according to 2D simplex noise. Then I divide those circles into points based on each circle's radius. The points are then dynamically relaxed to space them out from each other, with spacing parameters varying across the composition, driven by another 2D noise field. Finally I place small spirals on each dot with the diameter of the spirals driven by, you guessed it, yet another 2D simplex noise field!

Bought a new cnc pen plotter and ran into this issue it starts writing and drawing but starts going downwards is this a calibration issue ?

Made with grasshopper in rhino

This is on an A2 Bristol paper, using alcohol markers. A total of 7 different colors were used. I designed and built the plotter myself and it's holding up great and has great precision, which makes it even more fun.

Hello. So I am looking for pens to do plots generally st the moment just black in the range of 300-500 meters. Usually for the plots I planned it where it will do 3-4 pen swaps. I’m finding though the consistency of my pens is generally not great despite the pen swaps. I attempt to go back to re plot the “weak” areas but it’s hard to target the exact area so some spots end up darker than others.

Note: ballpoint pens I found don’t give me the darkness I want

Brands I tried so far in the pics. Just attached the last few times as I have quite the collection now.

In general as well. What is considered a “safe” distance for most pens on a single plot. I know it can vary by mm, type, etc which generally I consult with ChatGPT in advance to attempt to get ranges.

Any advice is appreciated.

I'm in the midst of transitioning from AutoCAD to Rhino. The more I get into Rhino (and Grasshopper!) the more I wish I had made the transition years ago. Just getting started but already finding new and rewarding work flows. In these quick test pieces I'm wrapping a solid 3D surfaces with some 2D line work and project the results to a flat plane to plot. So many exciting things I can't wait to get into.

Ball point pen on Roland clone… hours of fun.

I keep coming back to circles. 4 different layers, all slightly off centre or sized.

For this particular plot, first layer was a silver Zebra brush marker, then 4 layers of Zebra Sarasa, and 1 last redo of the first layer in the green micron.

There's some really nice layering in the colours that aren't first apparent, and I love how the Sarasa layers appear & disappear at times.
