* '''Location''' MechArtLab window sill
* '''Model''' HP LaserJet 3015P
* '''Purpose''' Printing two-dimensional objects in black & white
* '''URL''' ipp://npi0e1641.local/ (IPP) or socket://npi0e1641.local:9100 (JetDirect)
* '''Toner''' HP 55A (CE255A)

* '''Location''' Table near DigiGes entrance
* '''Model''' Brother QL550, Raspberry Pi 3B
* '''Purpose''' Printing sticky labels in black & white
* '''Features''' Label & sticker printing, generating QR code labels etc. Full feature set: [https://github.com/5shekel/printit/blob/master/README.md README]
* '''Options''' Transparent or non-transparent [white | pink] sticker rolls of 62mm width
* '''URL''' http://raspi-stikka.init5.ch:8980/ <small>* accessible within "Bitwäscherei-Bau" network</small>

==== Caveats ====
* The paper labels don't come off easily. After peeling off parts of it, you might have to use a solvent or duct tape to completely remove the remains.
==== Changing supplies ====
* 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'd like to add or improve a feature, the Stikka Printa source code can be found on [https://github.com/5shekel/printit GitHub]
* To access Stikka Printa via SSH, use l: dusjagr p: clubmate42

Caveats

  • The paper labels don't come off easily. After peeling off parts of it, you might have to use a solvent or duct tape to completely remove the remains.

Changing supplies

  • 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 🙏

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.
