   3 Uns wurde am 28.03.2014 eine CNC Maschine überlassen.
   4
   5 Hier wird es einmal der Ist-Zustand dokumentiert und dann mit dem Workflow zum Fräsen erweitert.
   6
   7 == Überblick ==
   8 === Fräse ===
   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
  12 * Kugelgewindetriebe
  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]
  18
  19 In der Fräse selbst steckt keine Logik, die Achsen werden über drei D-Sub-Buchsen aus der Fräse herausgeführt.
  20 Mit einer Kabelpeitsche werden diese über eine D-Sub-Buchse an der MPK3 Controller-Karte im Rechner angeschlossen.
  21
  22 === Rechner ===
  23 * AT-Industrie-PC-Gehäuse
  24 * Full-size ISA Intel Rechner 233 MHz CPU
  25 ** PIA-652DV 2.4 [ftp://ftp.arbor.com.tw/pub/manual/Manuals/PIA%20Series/pia-652-20.pdf Manual]
  26 ** 48 MB RAM (werden nur erkannt, es stecken mehr drin, EDO, sowie SD-RAM)
  27 * [[CNC-Fräse#MPK3|MPK3-Karte]]
  28 * Netzwerk-Karte
  29 * Zu viele Lüfter
  30 * CD-Laufwerk
  31 * Disketten-Laufwerk
  32 * EIN/AUS-Schalter an der Front
  33 * POWER und NOT-AUS-Taster für die Spindel an der Front
  34
  35 * 15" TFT 1024*768
  36 * Cherry-Tastatur und Kugelmaus
  37
  38 ==== MPK3 ====
  39 * Full-size ISA-Karte mit zwei D-Sub-Ausgängen an der Slotblende, Die große Buchse -> Fräse, die Kleine -> ?
  40 * Versorgt die Motoren der Fräse (mit Ausnahme der Spindel) direkt mit Strom
  41
  42 === Software ===
  43 * Win 98 SE
  44
  45 ==== Trimeta EdiTasc ====
  46 * Steuert die Fräse, schaltet Spindel ein/aus etc.
  47 * Lädt .ncp ("Zwischenformat) und .plt (hpgl)
  48 * Zeigt Pfade und Position (Nullpunkt, Spindelposition)
  49 * Kann simulieren
  50 * Papierdoku vorhanden
  51
  52 ==== isy3 ====
  53 * neueste installierte Version der isy-Programme (es gibt noch isy, isy1 und isy2)
  54 * DOS-Software
  55
  56 === Werkzeuge ===
  57 ==== Proxxon ====
  58 * 230V, 100W
  59 * 20k 1/min direkt am Gerät stufenlos verstellbar
  60 * Wird direkt an den Rechner angeschlossen
  61 * Mit Aufnahmen für verschiedene Einsatz-Durchmesser bis 3.2 mm
  62 * Hat derzeit einen Lagerschaden, reparabel.
  63
  64 ==== HF-Spindel ====
  65 * Wird von einem externen Netzteil mit Strom versorgt, das wiederum über "Fußpedal"-Anschluss mit Rechner ("HF-Spindel") verbunden wird
  66 * 50k 1/min
  67
  68 ==== Werkzeug-Einsätze ====
  69 * Siehe Bilder
  70
  71 == Erste Experimente ==
  72 [[Datei:CNC-Experimente.JPG|thumb|Erste CNC Experimente]]
  73 * Anschluss an ein [http://smoothieware.org/ SmoothieBoard]
  74 * Config angepasst (Siehe Upload von larsan)
  75 * Mit Eagle und [http://www.pcbgcode.org/ pcb-gcode] gcode erzeugt, auf SmoothieBoard übertragen und ausgeführt
  76 * Noch einige Probleme mit der Einstellung der Höhe(Z-Achse), da der Kleber unter der Platine etwas uneben war
  77

  79 === Smoothieboard config ===
  80 Eine erste config fürs Smoothieboard, liegt als ''config'' im Rootverzeichnis der µSD-Karte:

 329 ** http://psha.org.ru/irc/%23emc/2005-04-05.html
 330 *** <bagi> the current for each coil of the motor (2 coils - bipolar ) has to be set with one 8-Bit Port per coil.
 331 *** <cradek> that should be an easy modification to emcmot.c
 332 ** http://psha.org.ru/irc/%23emc/2005-04-12.html
 333 *** <bagi>  at the moment there is no driver for this card. it is an ISA PCB for 3  Steppers. for each motor 2 L292 and 2 8Bit for the current of the 2  coils.
