Uns wurde am 28.03.2014 eine CNC Maschine überlassen.
Hier wird es einmal der Ist-Zustand dokumentiert und dann mit dem Workflow zum Fräsen erweitert.
== Überblick ==
=== Fräse ===
Es handelt sich um eine etwa 15 jahre alte Isel Automation Flachbett Tischfräse CNC Multi K.
Kaum gebraucht und vermutlich seit ~9 Jahren nicht mehr in Betrieb gewesen.
* Arbeitsbereich: x*y*z mm
* Kugelgewindetriebe
* Zwei Endschalter pro Achse
* Derzeit zwei Frässpindeln verfügbar
** [[CNC-Fräse#HF-Spindel|Hochfrequenzspindel]]
** [[CNC-Fräse#Proxxon|Proxxon]]
* NEMA23 Schrittmotoren der Firma Nanotec [http://de.nanotec.com/fileadmin/files/Datenblaetter/Schrittmotoren/ST5918/ST5918M3008-A.pdf 4T5618M3300]
In der Fräse selbst steckt keine Logik, die Achsen werden über drei D-Sub-Buchsen aus der Fräse herausgeführt.
Mit einer Kabelpeitsche werden diese über eine D-Sub-Buchse an der MPK3 Controller-Karte im Rechner angeschlossen.
=== Rechner ===
* AT-Industrie-PC-Gehäuse
* Full-size ISA Intel Rechner 233 MHz CPU
** PIA-652DV 2.4 [ftp://ftp.arbor.com.tw/pub/manual/Manuals/PIA%20Series/pia-652-20.pdf Manual]
** 48 MB RAM (werden nur erkannt, es stecken mehr drin, EDO, sowie SD-RAM)
* [[CNC-Fräse#MPK3|MPK3-Karte]]
* Netzwerk-Karte
* Zu viele Lüfter
* CD-Laufwerk
* Disketten-Laufwerk
* EIN/AUS-Schalter an der Front
* POWER und NOT-AUS-Taster für die Spindel an der Front
* 15" TFT 1024*768
* Cherry-Tastatur und Kugelmaus
==== MPK3 ====
* Full-size ISA-Karte mit zwei D-Sub-Ausgängen an der Slotblende, Die große Buchse -> Fräse, die Kleine -> ?
* Versorgt die Motoren der Fräse (mit Ausnahme der Spindel) direkt mit Strom
=== Software ===
* Win 98 SE
==== Trimeta EdiTasc ====
* Steuert die Fräse, schaltet Spindel ein/aus etc.
* Lädt .ncp ("Zwischenformat) und .plt (hpgl)
* Zeigt Pfade und Position (Nullpunkt, Spindelposition)
* Kann simulieren
* Papierdoku vorhanden
==== isy3 ====
* neueste installierte Version der isy-Programme (es gibt noch isy, isy1 und isy2)
* DOS-Software
=== Werkzeuge ===
==== Proxxon ====
* 230V, 100W
* 20k 1/min direkt am Gerät stufenlos verstellbar
* Wird direkt an den Rechner angeschlossen
* Mit Aufnahmen für verschiedene Einsatz-Durchmesser bis 3.2 mm
* Hat derzeit einen Lagerschaden, reparabel.
==== HF-Spindel ====
* Wird von einem externen Netzteil mit Strom versorgt, das wiederum über "Fußpedal"-Anschluss mit Rechner ("HF-Spindel") verbunden wird
* 50k 1/min
==== Werkzeug-Einsätze ====
* Siehe Bilder
== Erste Experimente ==
[[Datei:CNC-Experimente.JPG|thumb|Erste CNC Experimente]]
* Anschluss an ein [http://smoothieware.org/ SmoothieBoard]
* Config angepasst (Siehe Upload von larsan)
* Mit Eagle und [http://www.pcbgcode.org/ pcb-gcode] gcode erzeugt, auf SmoothieBoard übertragen und ausgeführt
* Noch einige Probleme mit der Einstellung der Höhe(Z-Achse), da der Kleber unter der Platine etwas uneben war

** http://psha.org.ru/irc/%23emc/2005-04-05.html
*** the current for each coil of the motor (2 coils - bipolar ) has to be set with one 8-Bit Port per coil.
*** that should be an easy modification to emcmot.c
** http://psha.org.ru/irc/%23emc/2005-04-12.html
*** 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.
