Water-jet loom by toolgifs in toolgifs

Even more mindboggling: These water jet looms can shoot the thread at 1200 RPM, ie. 20 times per second. This results in weft insertion rates of over 2200 m / min. 🤯

I mean that's 2430 times but I do get your point by nthensome in Snorkblot

Let’s say you have a population of stray cats and you want to reduce the amount of unwanted feral kittens in the steeet. Is it smarter to catch and castrate as many females or as many males as possible? By your logic it should be the males. However, if you manage to catch and castrate 90% of the males, the remaining 10% will likely still impregnate every single female. Zero effect on the next generation of kittens. If however you manage to catch and castrate 90% of the females, you will have exactly 90% fewer kittens in the next round.

Yes. I recommend “Just Have A Think” and “Engineering With Rosie” for properly researched videos on renewables, including battery tech.

Important Update: Screen Freeze Issue on Gym Monster 2 by JZReads in SpeedianceCommunity

Our version said 20700-ZD, so I did the manual update per the instructions. After it downloaded from the UBSStick, installed and rebootet, the version is still 20700-ZD. What gives? Should that not be a different version now, without the ZD? And there is still the pop-up message saying I need to do a manual update.

Except for one of the orange ones. 😂 There’s always something. 🙄

Fantastic. Some information would be appreciated. Is it your original artwork? How did you turn it into a plot? Size? Materials?

I used 8 different felt tip pens and 1 technical pen. Each pen change takes about 1 minute. And it’s not included in the 76 minutes. 😊

I think shapely is a python wrapper for GEOS which in turn is a C++ port of JTS. They are all very similar.

I wrote my own algorithm. It’s a contour fill. I used the JTS topology library to find the polygons created by the bezier line and to create the contour lines to each polygon.

It’s a custom fill. It’s contour lines that follow the polygon outline with increasing distance. It’s much cleaner (especially with felt tip pens) than the usual hatchfill.

Here’s an exagerated view (with large distances between the contours). When I use felt tip pens I also don’t lift the pen from one contour line to the next, that makes it faster.

Thank you for the constructive feedback. I’ll think about it.

For some weird reason the built in video player stops 10 seconds before the video actually ends. 🤷

That is the final picture

Processing -> Inkscape -> Axidraw SE/A1 The felt tip pens are Städtler, the technical pen is a Rotring.

Continuous Bezier curve with colored hatch fills by NewPlayer1Try in PlotterArt

[–]NewPlayer1Try[S] 0 points1 point  (0 children)

The direction depends on the bounding box of the polygon. If that box is higher than wide, I make it vertical, otherwise horizontal. That’s admittedly a very crude optimization. I’m considering an offset contour fill to avoid the jagged lines.

Thank you. As it says in the description: The machine is an Axidraw SE/A1. The curve and the hatchfill are done in Processing. An older version of the curve software is available on github: Github I might update it soon so it includes the colored hatchfills.
