* If Stikka Printa isn't accessible on the known URL, the Raspberry controlling it might not be turned on, could have gotten a new IP from DHCP, or init5.ch DNS could be broken. Start by ensuring both the Raspberry and Brother QL550 are 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.

Voodoo Chicken Machine

Specs & Documentation

Usage

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

Maintenance

Changing sticker rolls

  • 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

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 power-cycle the Raspberry controlling Stikka Printa.
  • If Stikka Printa isn't accessible on the known URL, the Raspberry controlling it might not be turned on, could have gotten a new IP from DHCP, or init5.ch DNS could be broken. Start by ensuring both the Raspberry and Brother QL550 are 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 in case the URL has changed, and update the link in this Wiki 🙏

Software

  • If you feel like adding or improving a feature, the Stikka Printa source code can be found on GitHub
  • To access Stikka Printa via SSH, use l: dusjagr p: clubmate42







3D Printers Tools and Instructions

Best to directly connect to OctoPrint: http://octopi.local/ or install Cura on your laptop and use the SD cards reader.

Ender3Ender3 v2MicroDeltaUltimaker


Bed leveling for Ender 3 (& V2)

Check this movie: https://www.youtube.com/watch?v=4JSa_r8xgX8


Other resources

Currently a MicroDelta printer is installed, use the page linked to get started.


Design: Download Sketchup from http://www.sketchup.com/ => Design => Export .STL

Slice: Download Cura from http://software.ultimaker.com/ => Load .STL => Prepare => Write .GCODE to SD card

Print: Insert SD card into Ultimaker => Push, Scroll to Card => Select .GCODE => Push

Share: Upload model and .STL (but not .GCODE) to http://thingiverse.com/

First time? Ask @tamberg.


ORTUR Laser Master 2

The attached computer has already LightBurn installed, it's the best software to use many different laser machines: https://www.youtube.com/watch?v=YLhbvwq_EDc

You find drivers and firmware updates here: https://ortur.tech/olm2/

Hackaday wrote a few articles on mods and improvements, aswell as a nice discussion on open source hardware around the ORTUR company: https://hackaday.com/tag/ortur/

PCB Etching

Instructions on how to use the PCB etching facility can be found under PCB Etching.

Instructions for Mask design and print for custom PCBs.

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.
