HueForge TD Step Test and Light Box

While this step test still provides valid testing data, it can be difficult to properly interpret. If you want a way to quickly test for TD that takes all the guess work out, consider the TD-1. The TD-1 was developed with the support of HueForge and directly interfaces with the software for quickly testing and adding filaments to your library. More information can be found on my website AJAX-3D.

This is the TD (Transmission Distance) step test developed by me and the creator of HueForge(listed here with his permission). This test can be used to test the TD of your filament TDs.

Parts Needed

• LEDs ( These LEDs can be substituted with any 5v LEDs with a similar LED per inch density.) - https://a.co/d/1jn8OZ2
• USB-C Breakout board (Only needed for the USB-C box option) - https://a.co/d/eJuP9L9

Print Settings

• TD_Step_Test - 100% infill @ 0.2 layer, filament type and color you are testing.
• TD_Step_Test_Plus_4 - 100% infill @ 0.2 layer, filament type and color you are testing. - TD_Step_Test_Slide_In_Frame - 2+ walls 15% infill, 3-5 top and bottom layers, black/dark filament
• TD_Step_Test_Box_Top - 2+ walls 15% infill, 3-5 top layers, black/dark filament(choose from the three options.) For multicolor text, choose your color for the text.

Testing Filament

Place the step test into the viewing lid and with the led lights on check for the step where the light starts to dim to the point that any steps beyond are all the same brightness. The last step before the final dimming, is your calculated TD value. If all the steps are bright, print and insert a TD_Step_Test_Plus_4 of the same filament under the step test block and check again. This block adds 4 to the number on the top of the box. If adding one TD_Step_Test_Plus_4 block is still not enough, keep adding additional TD_Step_Test_Plus_4 blocks till the steps begin to dim.

Storage

I have also designed some Gridfinity storage bin that these snap into for convenient storage options.
