Mittlerweile stehen im Space mehrere 3D-Drucker, die alle auf unterschiedliche Weise bedient werden können. Um die Bedienung von allen vorhandenen 3D-Druckern zu vereinheitlich und zu vereinfachen, wurde Repetier-Server auf einem Raspberry Pi installiert. Hier soll die allgemeine Bedienung und die Einrichtung erläutert werden.

Zu den einzelnen Besonderheiten der Drucker siehe RepRap, LulzBot und TinyBoy.

Im Rahmen des Studium Generale an der TU Braunschweig gab es einen Vortrag von larsan, der eine grobe Einführung bietet. Die Slides dazu finden sich unter Datei:Stratum 0 3D-Druck-Vortrag Folien Studium Generale.pdf.

Hinweise zur Benutzung

So ein 3D-Drucker ist nicht gerade billig, deshalb müssen einige Regeln befolgt werden.

• Nur die #Druckberechtigten dürfen drucken.
• Kein Essen und Trinken am 3D-Drucker-Arbeitsplatz!
• Nicht an den Einstellungen herumspielen. Unbedachtes Ändern von Beschleunigungs- und Geschwindigkeitseinstellungen kann die Motoren und den 3D-Drucker beschädigen.
• Wenn der Drucker längere Zeit nicht druckt, stell sicher, dass die Heizung für den Extruder aus ist
• Das Filament muss ggf. per Hand nachgeführt werden, wenn es nicht von selbst abrollt.
  • Hacks: entsprechend positionierter Mikrofonständer als Abrollvorrichtung für die Rolle
• Die Plattform vor dem Drucken gründlich mit Alkohol oder Pinselreiniger säubern, wenn nicht auf Papier gedruckt wird. Das ist eine häufige Ursache für Probleme.
• Nach dem Drucken etwa 1-2 Minuten warten, bis die Teile abgekühlt sind, da sie sich ansonsten verformen.
• Manche Teile (besonders bei dünnen Strukturen) benötigen Kühlung, hierfür z.B. die Lüfter verwenden (siehe gedruckte Eule)
• Den Druck zwischendrin zu unterbrechen um später weiter zu drucken – und sei es nur für 5 Sekunden – ist mit unendlich viel Problemen behaftet und sollte wenn irgendwie möglich vermieden werden.

Schritt 1: 3D-Modell erstellen

siehe: 3D-Modell erstellen

3D-Modell als .stl-Datei bereitstellen.

Hierzu kann entweder ein eigenes Design erstellt werden (z.B. mit OpenSCAD, Tinkercad) oder ein bereits vorhandenes verwendet werden (z.B. von Thingiverse). Zum Umwandeln aus anderen 3D-Formaten eignet sich z.B. Blender.

Schritt 2: Slicen

Die .stl Datei in GCode wandeln.

Dieser Vorgang wird Slicen genannt und benötigt ein weiteres Programm. Im Stratum0 wird der Slic3r oder RepetierHost (bringt bei der Installation den Slic3r mit) verwendet.

Weitere Software (unsupported, YMMV):

• Cura
  • Beispiel-Konfiguration ist unter [1] zu finden. Achtung: Der Wert für die Nozzle muss auf 0.35 mm angepasst werden!
• Skeinforge
• SFACT (Fork von Skeinforge)

Slic3r-Einstellungen

Wenn Repetier-Host für das Slicen verwendet wird, sollte das eingebundene Programm Slic3r verwendet werden. Dazu den KAPUTTER LINK Download als .zip herunterladen, entpacken und anschließend im Repetier-Host unter Slicer bei Manager das Slic3r-Konfigurationsverzeichnis auf den entpackten Ordner verweisen. Jetzt sind alle .ini-Dateien, die zum Drucken notwendig sind, vorhanden.

Alternativ kann das folgende Config-Bundle in Repetier Host oder Slic3r importiert werden. In Slic3r geht das über den Menüpunkt „File“ → „Load Config Bundle“.

Hinweise

• Die Config muss nach jedem Start neu geladen werden
• Die Drucktemperatur sollte auf dem Filament stehen. Ansonsten ist 180°C-200°C eine gute Temperatur für PLA, 240°C für ABS.
• Der erste Layer sollte mit 10°C mehr gedruckt werden
• Es kann helfen, von Zeit zu Zeit die Version zu updaten

Schritt 3: GCode senden

Drucken durch senden des .gcode an den Drucker.

Bitte vor dem starten eines Drucks unbedingt die Düsenhöhe prüfen (sollte man bei der Einweisung gelernt haben). Sollte die Düsenhöhe nicht passen, bitte unbedingt jemanden fragen der sich wirklich damit auskennt.

Im Stratum0 wird Repetier-Server zur Bedienung der 3D-Drucker verwendet. Entweder wird der erstellte .gcode im Webinterface hochgeladen, oder durch RepetierHost an den Server gesendet. Anschließend kann der Druck über den das Webinterface gestartet werden.

Weboberfläche: Repetier-Server

Das Repetier-Server-Webinterfaces

Repetier-Server dient zum Hochladen und Verwalten von G-Code im Browser, sowie dem Starten von Drucken und das allgemeine Steuern der Drucker.

Der Webserver ist aus dem Stratum0 Netzwerk unter http://repetier.s0 (notfalls 192.168.178.147) zu erreichen:

• Benutzername: stratum0
• Passwort: stratum0 (you guessed it.)

Rechner: Repetier-Host

Neben der Möglichkeit, Repetier-Server über den Browser zu bedienen, kann auch Repetier-Host auf dem Rechner direkt zum Hochladen des G-Codes verwendet werden. Dies benötigt IP und API-Key:

• IP: 192.168.178.147
• API-Key: 7b47c015-8a6f-4ef9-811a-3929a335a7da

Rechner per USB

Schließlich gibt es noch Printrun/Pronterface/Pronsole, das zum Steuern des Druckers verwendet werden kann, wenn man ihn per USB anschließt (prinzipiell meldet sich der Drucker als serielle Konsole im System, aber du willst etwas mehr Komfort haben). Hiermit kann man insbesondere auch GCode zum Drucker schicken, was allerdings auch über die Weboberfläche kein Problem darstellt.

Fehler und Behebung

Eine sehr gute Übersicht an Fehlern und Ratschlägen zu deren Behebnung bietet Simplify3D jedoch sind viele Lösungen nicht ohne Eingriff in die Firmware anwendbar. Falls es es jemand wirklich für Notwendig erachtet Werte in der Firmware Dauerhaft zu ändern, spricht er bitte NoikK an.

Setup und Konfiguration

Port 80 statt 3344 für RepetierServer

Der Standardport des RepetierServers ist 3344, mehr konvenient ist aber Port 80. Um den Port zu ändern:

sudo vim /usr/local/Repetier-Server/etc/RepetierServer.xml 

Da Port 80 aber ein privileged Port ist, muss der RepetierServer-Binary noch die notwendige Capability gegeben werden:

sudo setcap cap_net_bind_service=+ep /usr/local/Repetier-Server/bin/RepetierServer

Ob das Binary die Capability bekommen hat, kann man mit getcap überprüfen:

sudo getcap /usr/local/Repetier-Server/bin/RepetierServer

Danach den Service (neu)starten:

sudo systemctl restart RepetierServer

Aussicht

Auf lange Sicht sollen alle 3D-Drucker vereinheitlicht werden. Dazu siehe https://pad.stratum0.org/p/3d-Drucker
