  14 Uns wurde am 28.03.2014 eine CNC-Maschine überlassen. Nachdem wir sie unter Verwendung des mitgelieferten Industrierechners ansteuern konnten, stellten wir fest, dass diese Methode nicht viel Zukunft haben würde. Kein USB, beschränkte Geschwindigkeit, laut, Win98 will man nicht im Netzwerk haben, etc.
  15
  16 Da die Fräse alle ihre Anschlüsse über D-Sub-Buchsen herausführt, wollen wir einen anderen Controller verwenden, der die Motoren direkt ansteuert. Am 24.05.2014 haben wir mit einem [https://smoothieware.github.io/Webif-pack/documentation/web/html/ Smoothieboard] erfolgreich die ersten Schritte in diese Richtung gemacht.
  17
  18 Stand 27.06.2014: Wir haben uns ein eigenes Smoothieboard 5X zugelegt, das wird derzeit in Betrieb genommen.

  34 == Überblick ==
  35 === Fräse ===
  36 [[Datei:CNC-Fräse Holzbalken.jpg|thumb|Durch den Aufbau als Portalfräse ist es möglich, dass Werkstücke in y-Richtung über den Frästisch hinausragen können]]
  37
  38 Es handelt sich um (Stand 2014) eine etwa 15 Jahre alte Isel Automation Flachbett-Tischfräse CNC Multi K.
  39 Kaum gebraucht und vermutlich seit ~9 Jahren nicht mehr in Betrieb gewesen, bevor sie 2014 zu uns kam.
  40 * maximaler Arbeitsbereich: (x,y,z) = (330 mm, 500 mm, 90 mm), abzüglich Befestigung und eingesetztem Fräser eher so z=70 mm
  41 * Kugelgewindetriebe
  42 * Zwei Endschalter pro Achse
  43 * Derzeit zwei Frässpindeln verfügbar
  44 ** <s>[[#HF-Spindel|Hochfrequenzspindel]]</s> defekt, siehe [https://gitli.stratum0.org/stratum0/TUWAT/-/issues/10 TUWAT]
  45 ** [[#Proxxon|Proxxon]]
  46 ** Kress
  47 * NEMA23 Schrittmotoren der Firma Nanotec [http://de.nanotec.com/fileadmin/files/Datenblaetter/Schrittmotoren/ST5918/ST5918M3008-A.pdf 4T5618M3300]

  49 ==== Motoranschlüsse an der Fräse ====
  50 Die Fräse führt an der Hinterseite 3 D-Sub DE-9 Buchsen heraus, die je für die Ansteuerung der X-, Y- und Z-Achse zwei Polepaaranschlüsse bereitstellt.

  63
  64 In der Fräse selbst steckt keine Logik, die Achsen werden über drei D-Sub-Buchsen aus der Fräse herausgeführt.
  65 [[Datei:CNC-Pinbelegungen auf dem 25Pin-Kabel.pdf|thumb|Die etwas komische Belegung der CNC-Fräse]]
  66 ==== Endschalter ====
  67 * X-Achse: Endschalter für min. und max. sind vorhanden
  68 * Y-Achse: Endschalter für min. und max. sind vorhanden
  69 * Z-Achse: Endschalter für min. und max. sind vorhanden
  70
  71 Die Entschalter mit NC (Normally Connected) an den jeweiligen D-Sub DE-9 Buchsen mit den Pins 5 (Common), 7 und 9 angeschlossen.
  72 Auf dem 25-Pol Kabel ist allerdings Pin 9 Common. Das sollte sich durch umlöten der Stecker an der CNC-Fräse aber ändern lassen.
  73
  74 === Werkzeuge ===
  75 ==== Proxxon ====
  76 * 230V, 100W
  77 * 20k 1/min direkt am Gerät stufenlos verstellbar
  78 * Wird direkt an den Rechner angeschlossen
  79 * Mit Aufnahmen für verschiedene Einsatz-Durchmesser bis 3.2 mm
  80 * Das vordere Lager wurde durch Proxxon kostenlos getauscht und ist somit wieder i.O.
  81
  82 ==== HF-Spindel ====
  83 * Wird von einem externen Netzteil mit Strom versorgt, das wiederum über "Fußpedal"-Anschluss mit Rechner ("HF-Spindel") verbunden wird. (Kann kurzgeschlossen werden, die Spindel ohne den Rechner zu betreiben.
  84 * 50k 1/min
  85
  86 ==== Werkzeug-Einsätze ====
  87 * Siehe Bilder

  99 [[Datei:CNC-Experimente.JPG|thumb|Erste CNC Experimente]]
 100 * Anschluss an ein [https://smoothieware.github.io/Webif-pack/documentation/web/html/ SmoothieBoard]
 101 * Config angepasst (Siehe Upload von larsan)
 102 * Mit Eagle und [http://www.pcbgcode.org/ pcb-gcode] gcode erzeugt, auf SmoothieBoard übertragen und ausgeführt
 103 * Noch einige Probleme mit der Einstellung der Höhe(Z-Achse), da der Kleber unter der Platine etwas uneben war
