Wanted to use Octoprint on a raspberry pi zero w because of its small footprint and low power usage.
Warning: The zero w will not work with a camera the CPU usage is hight negatively impacting printing results.
- 1 x Boost Buck Converter XL6009
- 2 x T Block Square nuts 2020 m3 or printed version
- 1 x raspberry pi zero w
- 1 x 16gb sd card
- 2 x xt60 plug pair
- 30cm+ 14awg silicone cable
- 1 x 1k ohm resistor
- 2 x M3 Brass knurled female thread insert
- 4 x 19mm M3 screw
- 1 x 5mm M3 screw
- 1 x M3 nut
- 2 x zip ties
- Heat shrink tubing
- Hot glue or double sided tape (for the xt60 y connector)
- 1 x usb mini B to usb
- Download the os
- Use etch flash the image onto a sd card
- Edit the octopi-wpa-supplicant.txt with your wifi credenciales.
- Connect to the octopi and finish the setup process.
You can print most of these without supports. The models can be found in "./models" the source files are there with the stl. The models where made with sketchup
- 1 x xt60_y_connector (no support)
- 1 x pi_base (no support)
- 1 x boost_base (no support)
- 1 x case (touching buildplate support)
- 2 x spacer_pi (touching buildplate support)
- 1 x spacer (no support)
The only clean up needed should be drilling the holes so the screw can move freely. Add the two brass inserts to the pi_base and the parts will be ready to be assembled.
The pi pads with labels
- Creating the xt60 Y connector.
- Use the left over male connector with the 14awg cable to create the wiring to the buck converter.
- Set the buck converter to a little under 5v.
- Wire power to the pads under the raspberry pi.
- Cut the male usb mini b cable to length and strip.
- add the 1k ohm resistor between the +5v on the pi and the red wire from the usb mini.
- wire the rest, black to gnd, green to d+ and white to d-. (on my usb mini cable I had to swap d+ and d-)
