Voodoo Chicken Machine

Specs & Documentation

• Model: Automata Eva
• Documentation: Eva Docs
• Gripping Tool: Schunk EGP 50-N-N-B

Connectivity

The WebUI is accessible either through

• its own Access Point, SSID "Eva-Playful Lima Dancer"

or

• statically assigned IP on its Ethernet interface

Caveats

• collision detection can fire due to vibrations when Eva isn't properly attached to the ground
• make sure to configure the size of the attached tool in Choreograph to prevent collisions
• ensure the READY LED on the Schunk gripper is solid green, otherwise reboot Eva

2D Printers

Maintenance

To change the sticker roll

• Open the cover
• Pull orange lever up
• Remove previous roll
• Insert new roll
• Feed new roll through front feeder
• Push orange lever back down
• Close cover

Software

• If you feel like adding or improving a feature, the Stikka Printa source code can be found at https://github.com/5shekel/printit

Debugging

• The software sometimes chokes on large, high-frequency print jobs, and no more stikkas are coming through. In that case, the easiest is to briefly remove power from the Raspberry controlling Stikka Printa.
• If Stikka Printa isn't accessible on the known URL, it might not be turned on, got a new IP from DHCP, or init5.ch DNS could be broken. Start by ensuring it's turned on, and scanning the BW network range for port 8980 using something like: nmap -sS -p 8980 --open -oG - 10.168.0.0/24. Once recovered, please print a new QR label with the updated URL, and update the link in this Wiki 🙏

Oven for Reflow and PDMS

There is a temperature sensor in the oven connected to an arduino that can be read through serial terminal. At the moment the sensor is mounted at the wrong position and shows around 40° less than the real temperature in the moddle of the oven. more about the code and connection of the temperature sensor is documented.
