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.
-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 [http://smoothieware.org/smoothieboard Smoothieboard] erfolgreich die ersten Schritte in diese Richtung gemacht.

Stand 27.06.2014: Wir haben uns ein eigenes Smoothieboard 5X zugelegt, das wird derzeit in Betrieb genommen.

==== Motoranschlüsse an der Fräse ====
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.
Pinbelegung D-Sub DE-9 Buchsen
