3 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.
5 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.
9 Es handelt sich um eine etwa 15 jahre alte Isel Automation Flachbett Tischfräse CNC Multi K.
10 Kaum gebraucht und vermutlich seit ~9 Jahren nicht mehr in Betrieb gewesen.
11 * Arbeitsbereich: x*y*z mm
13 * Zwei Endschalter pro Achse
14 * Derzeit zwei Frässpindeln verfügbar
15 ** [[CNC-Fräse#HF-Spindel|Hochfrequenzspindel]]
16 ** [[CNC-Fräse#Proxxon|Proxxon]]
17 * NEMA23 Schrittmotoren der Firma Nanotec [http://de.nanotec.com/fileadmin/files/Datenblaetter/Schrittmotoren/ST5918/ST5918M3008-A.pdf 4T5618M3300]
19 In der Fräse selbst steckt keine Logik, die Achsen werden über drei D-Sub-Buchsen aus der Fräse herausgeführt.
24 * 20k 1/min direkt am Gerät stufenlos verstellbar
25 * Wird direkt an den Rechner angeschlossen
26 * Mit Aufnahmen für verschiedene Einsatz-Durchmesser bis 3.2 mm
27 * Hat derzeit einen Lagerschaden, reparabel.
30 * 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.

44 == Erste Experimente ==
45 [[Datei:CNC-Experimente.JPG|thumb|Erste CNC Experimente]]
46 * Anschluss an ein [http://smoothieware.org/ SmoothieBoard]
47 * Config angepasst (Siehe Upload von larsan)
48 * Mit Eagle und [http://www.pcbgcode.org/ pcb-gcode] gcode erzeugt, auf SmoothieBoard übertragen und ausgeführt
49 * Noch einige Probleme mit der Einstellung der Höhe(Z-Achse), da der Kleber unter der Platine etwas uneben war
51 === Smoothieboard config ===
52 Eine erste config fürs Smoothieboard, liegt als ''config'' im Rootverzeichnis der µSD-Karte:
