FABRICATION FILES¶
The fabrication files for this project are, The Grasshopper definition1, for the pattern The pattern was created through various steps so the file contains definitions with other pattern protoypes, titled in the definition. The final pattern definition is at the top.
The Tiff files for the TC2 weaving loom were made in Adobe Photoshop with these weaving structures 2 . The final weaving files were done in three parts either slitting the warp in two or three strings, being the Blue and pink pieces3, Green and purple 4, and Orange and blue pieces 5,
How-Tos & Tutorials¶
How to build the parametric design in grasshopper¶
The building of the pattern definition starts by downloading the Rhino 7 software and Firefly plugin.
All definitions are named in the file so it is accessible. Start by plugin the webcam to the computer and right click on the webcam definition in grasshopper where you can choose the correct webcam. To start recording the pattern, press play on the webcam bottom right corner and push the red button on the recording definition.
- To change the lenght of the pattern recording, right click on the recording definition, click on record limit and cange to desired length, higher number means longer pattern.
- To cange the space between lines, move the slider with the same name connected to Series
- To cange the width of the pattern, move the slider named width of textiles connected to construct point - x-coordinate
- To change the point per line, meaning how many curves are created in each line, move the slider named point per line connected to count in devide curve
- To cange color on the pattern choose a color gradient and connect it to diffuse and transparency on create material definition
How to make a file for TC2 in Photoshop¶
The Tc2 digital loom connects to a TC2 computer software and from there can read JPG, TIFF, BMP and WIF files. The Controller software also runs under Linux and MAC. The Loom Driver software is included in the package, but no computer or design programs such as Photoshop. I use photoshop since the software can only be connected to one computer.
This is the TC2 software interface when it is working on a file created with photoshop.

Start of by knowing the number of threads in the warp. The number of threads equals the number of pixles of the file width in photoshop. Here they were 1278 so the file is 1278 px wide and 3000 px high. Add preferd design into the your file with the right pixle mesurments. The maximum of colors to work with with the pattern used here is 8 colors. To get 8 colors go to image - mode - indexed color. from there in palette choose Local(adaptive) and type in the number 8. Now you only have 8 colors in your file.

As you can see in the tutorial below, each color needs to be on seperate layers and to do so use the magic wand tool and click on each color and with each color chossen make a new layer. In the end you have 9 layers, the base layer with the original picture and the other 8 holding on color in each layer.
When you have each color in sepaerate layer you can add the weaving patterns2, choosing a different pattern for each layer. The pattern is for two shuttles meaning you can work with two colors for the weft and it has 7 different gradients. The gradient varies from a strong A color mixing more and more with B color ending with a strong B color. To add a pattern to a seperate layers, click on Fx in the bottom of the layers and click on pattern overlay. From there you can choose one of the pattern from a gradient go over the preferd color. Make sure the pattern is 100% in scale. Always choose a different pattern for each layer.

To see how you file will approximetly turn out with two color you can make add a simulation layer. On top of the layers add a new layer, click on edit - fill and fill with pattern. The pattern you choose is one of the two colors simulations. Now it may seem like everything has dissapearn and you only have stripes of the A/B color. To change that click on, above layers, normal and change it to darken and voila!
Save the file as a TIFF file
How to set up the loom for weaving¶
To set up the weving loom, start by knotting the warp to the fabric beam. Do so by deviding the warp into even thread bundels , start knotting from the middel and the from the the outer edges and inward moving from one side to the other so get an even stretch on the warp.
How to weave on the TC2¶
Even though the weaving loom is digitally controlled, it is still manually operated. The opperation is though many times easier and easier on the mind, not having to always remeber which number of pedal you steped on before and so on. On the TC2 there is only one pedal to step on to change which threads go up and not - depending on the weaving patterns put in earlier in photoshop. Black pixles tell the thread to go up and white to stay down and for each row the threads play accordingly, with each step slowly revealing the complete design. For each step on the pedal one shuttles is pushed accross, between the warp threads and the with the next push on the pedal and another change is made in the warp thread and the next shuttle can gross the warp, each time beating the reed to push the weft evenly down.
How to finish textiles¶
When the weaving is finished, the material needs to be cut off the loom. It is best to do so in parts to be shure not to loose any threads through the reed and heddles, that would be sad. First role off the warp beem to release the tention on the warp threads. Then take a bundle off warp threads and with good scissors cut evenly and create a easily removable node. When finished you can role off the fabric beem and look at the magic that was created!
Because I wove 2 or 3 weaving panels at a time I made shure to have enough space between the pieces with and edge so I could cut them in the end with a nice finish. For the weft not to unravle I used textile glue in the edges before cuting them up.
Fabrication files¶
Here is a link to a drive keeping all the files and tutorials to make TC2 weaving files in photoshop - I will keep updating it and put more information as I work more on the project!
