XIAO ESP32-C6

Microcontroller

1

I also tested it with XIAO ESP32-C3 and it works well. I used the C6 because it has an integrated antenna.

TMC 2226

Stepper driver

2

TMC 2209 also work

5V step down module

1

The step down module takes the input voltage and reduces it to 5V for the LEDs and the microcontroller. The module I used seems to be proprietary for this Czech e-shop. https://dratek.cz/arduino-platforma/1738-step-down-modul-napajeni-mini-buck-nastavitelny.html I thought it would be more widely available. Nevertheless, any DC/DC 5V buck converter should work as long as it's connected in the same way.

B5B-XH-A

5-pin Motor connector

For mounting the XIAO

8-pin headers

For mounting the drivers

B3B-XH-A

3-pin connector

For connecting the LED strip

PJ-002A

DC power connector

28BYJ-48

Stepper motor

2

The steppers are modified for bipolar drivers! Check out this tool: https://www.printables.com/model/1814506-28byj-48-stepper-bipolar-mod-drill-jig-gridfinity

WS2812B 60 LED/m

LED light strip

25 cm

I used self adhesive strip. At 60 LED/m the 25 cm section has 14 LEDs.

608

Ball bearing 608

4

Probably the most common bearings out there

DIN 7982 3x12

Short screw

4

This screw holds the motors in place. It's possible to use different length up to 16 mm. Also It work with standard DIN 912 bolts as well, the bolt will cut it's own thread

DIN 7982 3x25

Long screw

3

For attaching the bottom lid

DIN 912 3x6

Inbus bolt

4

For attaching the PCB

DIN 912 4x50

Inbus bolt

1

Goes through the shaft

DIN 562 m4

Square nut

1

Fixes the shaft with the 4x50 bolt

⌀6x2mm N42

Magnet

16*

These are the same magnets people use in gridfinity boxes. *The mechanims uses 8 magnets and each disc also uses 8 magnets.

There is also a file called 04P08-front_flange it's the same thing but puts the discs closer together. I recommend the higher version as the discs can be sligthly bent and get into collide.
