Hi this is 100% custom .gcode made in grasshopper, there is some basic principles to learn first about grasshopper generated gcode, this is one of the best contents available at YT, https://www.youtube.com/live/u4g4EYzSp38?si=F8FnhcxfFIAeM2H6
I am also trying to develop my own custom woven effect custom gcode, I started this week with some tests and I was able to send it properly to the machine.
Please be aware of the X Y Z coordinates to avoid sending code out of your print bed limits.
The reason why you don’t see a lot of people posting how to do it , it’s because it takes some time to develope it, and the configuration will vary a lot depending on the machine.
If you check this video you will see the process to do it!
To resume - create a shape using loft or adding a brep at grasshopper, apply contours, then the distance of the contours will be your layer line, you have to add a effect for each layer line, you will need lists for that, and after you have to conect everything to form a single polyline path ,
Hope it can help
