SMD Solderingstation
|
|
||||||
|
## SMD Lötstation, kompatibel zu Weller-Lötspitzen
|
||||||
|
|
||||||
|
Weller baut seit Jahren *die* Lötstationen für den professionellen Bereich.
|
||||||
|
Die WMRP/WXRP-Stationen heben sich durch ihre aktiven Lötspitzen von anderen Produkten ab.
|
||||||
|
Mit einer außergewöhnlich kurzen Aufheizzeit im Sekundenbereich, einer direkt in der Spitze integrierten Temperaturmessung und dementsprechend schnelle Nachregulierung in Sekundenbruchteilen sind die Spitzen in der Industrie äußerst beliebt.
|
||||||
|
Die Spitzen selbst sind für 40€ im Handel erhältlich, die original Weller-Station kostet an die 600€.
|
||||||
|
Für den einfachen Maker oder Hobbyist auf keinen Fall ein Produkt, das beim Onlineshopping ohne weitere Überlegungen in den Warenkorb wandert.
|
||||||
|
Der *Maiskolben* hingegen ist eine erschwingliche Lösung für lediglich 40€, mit der die Spitzen ebenso angesteuert werden können.
|
||||||
|
|
||||||
|
* Betrieb mit 12V Netzteil oder 3s LiPo (Modellbau-Akku)
|
||||||
|
* Spannungsüberwachung (bei Akku für alle 3 Zellen und automatische Abschaltung bei zu geringer Ladung)
|
||||||
|
* Einfaches Wechseln von Spitzen mittels Klinken-Buchse/-Kabel
|
||||||
|
* 3 individuelle Temperatur-Presets
|
||||||
|
* Temperaturbereich von 100-400°C
|
||||||
|
* Gut ablesbares Farbdisplay mit allen nötigen Informationen
|
||||||
|
* Auto-Standby (entweder sensor- oder zeitgesteuert auf 150°C)
|
||||||
|
* Auto-Wakeup (entweder sensorgesteuert oder durch berühren von Lötschwamm, Messingwolle oder Lötstelle)
|
||||||
|
* USB-Schnittstelle zur Überwachung oder Steuerung mittels PC
|
||||||
|
* Potentialausgleich-/ESD-Buchse (über 1MΩ an GND)
|
||||||
|
* Optisches Feedback der Heizleistung durch LED
|
||||||
|
* Open-Source-Software auf Basis von Arduino
|
||||||
|
* Software-Update kann per USB eingespielt werden
|
||||||
|
|
||||||
|
## Stromzufuhr
|
||||||
|
|
||||||
|
Die Stromzufuhr wird wahlweise über die Hohlstecker-Buchse (10-18V) *ODER* die JST-XH4 (11,1V) Buchse angeschlossen.
|
||||||
|
Niemals beide gleichzeitig anschließen!
|
||||||
|
Der Lötkolben (Weller RT-XX, z.B. RT-1 für feine Lötarbeiten) wird über die Klinkenbuchse mit einer Verlängerung angesteckt.
|
||||||
|
|
||||||
|
## Display
|
||||||
|
|
||||||
|
Das Display zeigt mittig in weißer Schrift die Soll-Temperatur, darunter, sofern eine Spitze eingesteckt ist, die aktuelle Ist-Temperatur.
|
||||||
|
Bei eingeschaltetem Lötkolben erscheint zusätzlich noch die Zeit, nach der sich der Lötkolben automatisch in den Standby versetzt.
|
||||||
|
Der Balken am oberen Bildschirmrand spiegelt die Ist-Temperatur wieder.
|
||||||
|
Oben Links wird die Spannung bzw. die Ladezustände der einzelnen Zellen angezeigt.
|
||||||
|
Links wird durch das Power-Symbol der aktuelle Zustand (aus = rot, Standby = gelb, an = grün) signalisiert.
|
||||||
|
Am unteren Rand sind die drei Presets zu sehen.
|
||||||
|
|
||||||
|
## Bedienung
|
||||||
|
|
||||||
|
Nach dem Anstecken von Netzteil und Lötspitze kann die Station durch halten der Power-Taste (unten rechts) eingeschaltet werden.
|
||||||
|
Basierend auf der letzten Einstellung wird die angezeigte Soll- (Power-Symbol grün) oder die Standby-Temperatur (Symbol gelb) angefahren.
|
||||||
|
Mittels der Tasten rechts vom Display (Pfeile) lässt sich die Soll-Temperatur nach oben und unten korrigieren.
|
||||||
|
Sollte einer der Pfeile auf dem Display ausgegraut sein, so lässt sich über diese Temperatur hinaus keine weitere Änderung mehr vornehmen (100 ≥ T ≥ 400).
|
||||||
|
Mittels der Preset-Tasten unter dem Bildschirm lassen sich voreingestellte Temperaturen als Soll-Temperatur setzen und die Station gleichzeitig aus dem Standby aufwecken.
|
||||||
|
Durch gedrückthalten einer der drei Tasten wird der dort gespeicherte Wert durch die aktuelle Soll-Temperatur überschrieben.
|
||||||
|
Wird die Power-Taste nur kurz gedrückt, so wird der Standby-Zustand umgeschaltet.
|
||||||
|
|
||||||
|
## Fehlermeldungen
|
||||||
|
|
||||||
|
#### USB power only/Connect power supply; Power too low/Connect power >5V
|
||||||
|
Die Lötstation wird entweder nur über USB oder eine Spannungsquelle mit knapp 5V versorgt.
|
||||||
|
Zum Betrieb wird ein adäquates Netzteil oder Akku benötigt (≥40W)
|
||||||
|
|
||||||
|
#### NO TIP; No tip connected/Tip slipped out?
|
||||||
|
Es wurde keine Spitze eingesteckt oder nicht erkannt.
|
||||||
|
Es kann sein, dass die Spitze defekt ist oder nicht richtig in der Buchse steckt.
|
||||||
|
|
||||||
|
#### Temperature dropped/Tip slipped out?
|
||||||
|
Es wurde ein zu großer Temperaturabfall bemerkt und die Wahrscheinlichkeit besteht, dass die Spitze leicht aus der Buchse herausgerutscht ist.
|
||||||
|
Durch das Herausrutschen kann eine Verbindung zwischen Masse und dem Sensor hergestellt werden, sodass die erkannte Temperatur beim Offset von 24°C liegt.
|
||||||
|
|
||||||
|
#### Not heating/Weak power source or short
|
||||||
|
Entweder kann die Stromversorgung nicht genug Leistung bringen, um die Spitze in einem angemessenen Zeitraum aufzuheizen oder es liegt wie bei obigem Fehler ein Kurzschluss von Masse und Sensor vor.
|
||||||
|
|
||||||
|
#### Battery low/Replace or charge
|
||||||
|
Der Akku hat auf mindestens einer Zelle eine zu geringe Spannung und sollte ersetzt oder geladen werden.
|
||||||
|
|
||||||
|
Fehlermeldungen müssen durch OK bestätigt werden.
|
||||||
|
Die Fehlermeldungen können nicht unterdrückt werden, sollte allerdings mehrfach hintereinander eine Meldung bestätigt und die Station wieder eingeschaltet werden, kann dies zu übermäßigem Erwärmen der Lötspitze führen.
|
||||||
|
|
||||||
|
## Software-Update
|
||||||
|
|
||||||
|
Um die aktuellste Software auf den Maiskolbe zu übertragen, muss zunächst die [Arduino-IDE](https://www.arduino.cc/en/Main/Software) heruntergeladen werden.
|
||||||
|
In diesem Repository befinden sich zwei Programme, zum einen Maiskolben_LCD für die Hardware-Revision 1.0 und Maiskolben_TFT für Hardware-Revisionen ab 1.5.
|
||||||
|
Die .ino Datei kann mit Arduino geöffnet werden.
|
||||||
|
Der Serielle-Port muss nach Herstellen einer Verbindung zwischen Maiskolben und PC unter _Werkzeuge_ > _Port_ ausgewählt werden.
|
||||||
|
Unter umständen muss zuvor noch der [Treiber](http://www.wch.cn/download/CH341SER_ZIP.html) für den USB-Seriell-Wandler installiert werden.
|
||||||
|
Als _Board_ sollte _Arduino Nano_ mit _Prozessor_: _ATmega328_ ausgewählt werden.
|
||||||
|
Über _Sketch_ > _Hochladen_ bzw. den Pfeil nach Rechts in der oberen Leiste kann das Programm übertragen werden.
|
||||||
|
|
||||||
|
Unter umständen müssen vorher folgende Libraries noch über _Sketch_ > _Bibliothek einbinden_ > _.ZIP Bibliothek hinzufügen..._ eingebunden werden:
|
||||||
|
|
||||||
|
* [TimerOne](https://github.com/PaulStoffregen/TimerOne)
|
||||||
|
* [PID_v1](https://github.com/br3ttb/Arduino-PID-Library/)
|
||||||
|
* [Adafruit_ST7735](https://github.com/adafruit/Adafruit-ST7735-Library)
|
||||||
|
* [Adafruit_GFX](https://github.com/adafruit/Adafruit-GFX-Library)
|
||||||
|
|
||||||
|
### Changelog
|
||||||
|
|
||||||
|
* 2.0 Initiale Version für GitHub (TFT)
|
||||||
|
* Auto-Standby hinzugefügt
|
||||||
|
* Parameter angepasst
|
||||||
|
|
||||||
|
### Achtung!
|
||||||
|
|
||||||
|
Zur eigenen Sicherheit vor einem Software-Update die Lötspitze entfernen.
|
||||||
|
Zwar wird die Heizspannung beim Übertragen deaktiviert, dennoch kann es vereinzelt zu Fehlfunktionen und dadurch bedingtem unbeschränkten Aufheizen der Spitze kommen.
|
||||||
|
|
||||||
|
Modifikationen an der Software sind auf eigene Gefahr des Nutzers.
|
||||||
|
|
||||||
|
## Umbauten
|
||||||
|
|
||||||
|
Nachfolgend werden Modifikationen beschrieben, die die Funktionen des Maiskolben erweitern.
|
||||||
|
Für eigens durchgeführte Änderungen kann keine Haftung übernommen werden.
|
||||||
|
|
||||||
|
### Ablage-Sensor nachrüsten
|
||||||
|
|
||||||
|
Statt des automatischen Standbys nach einer bestimmten Zeit kann auch der Standby durch einen Ablage-Sensor erzwungen werden.
|
||||||
|
Auf der Platine befinden sich Kontakte mit STBY, 5V und GND.
|
||||||
|
Um den Standby zu aktivieren muss STBY mit GND verbunden werden, um wieder aufzuwachen muss die Verbindung getrennt werden.
|
||||||
|
Das Schalten von STBY nach GND kann entweder durch einen Schalter erfolgen, der beim auflegen der Spitze auslöst, alternativ mit einem Hall- oder Reed-Sensor.
|
||||||
|
Für letzteres muss an dem Ende des Klinken-Kabels, an dem die Spitze eingesteckt wird, ein Magnet angebracht werden, der den Sensor dann auslöst.
|
||||||
|
|
||||||
|
### Stromversorgungs-Schalter
|
||||||
|
|
||||||
|
Ab Hardware-Revision 1.5 gibt es auf der Platinenunterseite eine Lötbrücke mit der Beschriftung ON/OFF.
|
||||||
|
Bis einschließlich Revision 1.9 wird beim Durchtrennen dieser Brücke die gesamte Stromversorgung unterbrochen.
|
||||||
|
Ab Revision 1.11 wird hingegen nur noch die Zuleitung des LiPos getrennt.
|
||||||
|
An den beiden Lötpunkten können nach dem Durchtrennen der Leiterbahn Kabel zu einem Schalter gelötet werden, mit dem sich die Stromversorgung unterbrechen lässt.
