====== 3D Printer ======

===== New Members =====

Please get an introduction from one of the existing members before using the printer.

===== Responsible Persons =====

Currently:
  * charly
  * dazz
  * hrmny
  * ligi

==== Requirements ====
  * Must be a c-lab member
  * Wants to print regularly
  * Will take care of maintenance
  * Prints for other members when needed
  * Regularly at c-base

===== Private Prints =====
Station projects always take priority!

==== Costs ====
  * 0.03€/g (PLA, PETG)
  * 0.01€/g (own filament)

Round up to the next euro.

===== Print Protocol =====

==== Slicer ====
OrcaSlicer: https://github.com/SoftFever/OrcaSlicer

==== Before Printing ====
  - Check the waste container, empty if necessary
  - If filament has been inserted, place a filament swatch in the holder to indicate which filament is in which AMS slot
  - Ensure all parts are in proper condition
  - Select the appropriate build plate for the material and workpiece

==== Start ====
  - Matrix Message:
    * Who
    * What
    * Until when
    * If necessary, material (for ABS, ASA, etc. due to VOCs)
  - Note on the printer:
    * Same as the Matrix message
  - For materials with VOC emissions:
    * Open window
    * Send message to the c-lab mailing list
  - Check the first layer

TODO: Automate matrix message via MQTT?

==== During Printing ====
  * For long, complex print jobs, regularly check the print status (every $x hours)

==== After Printing ====
  * Ensure the nozzle is free of residue
  * Clean the print bed and place it back properly
  * If own filament was used, store it in personal boxes or take it with you
  * If something was consumed or damaged, it must be reported in the internal channel
  * If the printer is no longer in use, turn off the switch; otherwise, it should be turned off during shutdown

===== General Rules =====
  * Station projects always take priority.
  * Private filament may only be stored in member boxes at the c-lab.
  * BambuLab filaments are preferred.
  * Glue sticks should not be used, except on personal plates.
  * Avoid ABS, ASA, etc. until we have ventilation or air filtration.
  * Do not use the Smooth Build-Plate for PETG.
  * Unlabeled filament becomes part of the c-base stock.
  * Knowledge exchange should take place in the public channel.
  * The internal channel is for coordination and voting purposes only.

===== 3D Printing Matrix Group =====

==== Membership in the 3D Printing Group ====
  * All members have read, understood, and agreed to these rules (this page)
  * Members must be part of the internal 3D printing Matrix channel

==== Printer PIN ====
  * All members receive the printer PIN
    * **The PIN must not be shared**
  * The PIN is rotated regularly and posted in the Matrix channel

==== Maintenance ====
The group ...
  * Purchases new filament for c-base projects
  * Buys missing materials (spare parts, build plates)
  * Prints filament swatches if not yet available

===== Voting =====
  * In the Matrix channel
  * 1-week duration
  * All members must vote
  * Repeated failure to vote may result in exclusion

==== Admission ====
Max 1 per week
  * Simple majority

==== New Rules ====
After discussion in the Matrix channel
  * Simple majority
