Grotti 3.7.0: Treiber für Kobra 4 und Marlin, smartere Dateien-Auswahl und einstellbare Etiketten.

Senden und Abbruch laufen über den Treiber, Orca-Doppelzeilen und tote Ideen-API fallen weg, Drucker folgen der Datei, Etikettenformat liegt in den Einstellungen.

 ## [Unreleased]
 
+## [3.7.0] – 2026-11-02
+
+### Neu
+
+- **Treiber:** Moonraker bleibt der Weg für Kobra 3 und S1 (Rinkhals, kein Firmware-Restart). Kobra 4 spricht die Stock-Firmware über den LAN-Broker (Info, ACE-Plätze, Upload auf `fileUploadurl`, Start per MQTT). Die laufende Farm auf dem Pi bleibt auf Moonraker.
+- **Marlin:** Eigener Dienst hält die USB-Leitung. Grotti startet ihn selbst, sobald ein i3 oder Tenlog eingetragen ist, und beendet ihn nicht. Läuft er schon, bleibt er über einen Neustart von Grotti hinweg. Start pro Auftrag als Strom oder SD-Karte (`marlin_mode`: `stream` oder `sd`). Anycubic i3 ein Kopf, Tenlog zwei Köpfe (T0/T1, auf der Wand beide Temperaturen). Kein ACE, kein Heiz-Panel. Auf dem Pi liegt der Prozess in `grotti-marlin.service`.
+- **Problem melden:** Knopf in der Kopfzeile. Kopie lokal für den Admin der Installation, dazu Versand an den Empfänger auf git.gundel.dev (Issue). Token nur dort.
+- **Etiketten:** Papierformat in den Einstellungen (Standard 70×40 mm, Presets, `@page`).
+
+### Geändert
+
+- **Senden:** Upload und Start laufen über den Treiber (Moonraker-Vorbereitung unverändert). Hand-Abbruch in der Warteschlange stoppt Marlin und Kobra 4 ebenfalls.
+- **Ideen:** API und Store entfernt; `/ideen` bleibt Weiterleitung auf Aufträge. Tabelle `ideas` bleibt.
+- **Dateien:** Beim Wechsel der Datei bleibt der Drucker nur, wenn Familie und Rolle passen — sonst der passende freie. Orca-Upload und Watch-Kopie derselben Datei werden zusammengelegt (`watch_dir_local` in `orca-senden.json`).
+- **Live-UI:** Drucker-Ereignisse zeichnen Wand und Zieldrucker nur noch einmal und nur bei geändertem Markup; Karten werden nicht mehr bei jedem Tick umgehängt.
+- **Dateien / Wand / Material / Einstellungen:** Familien Kobra 4, i3 und Tenlog. Bettnetz nur bei Moonraker, Strom/SD bei Marlin, Mainsail nur bei Moonraker, Fehler löschen über den Treiber, Platzwahl nach Drucker (ACE / Köpfe / am Drucker), Host-Feld folgt der Familie.
+
+## [3.6.1] – 2026-11-01
+
+### Behoben
+
+- **Abbruch fehlt nach Neustart:** Der History-Abgleich hat den Live-Lauf übernommen und gelöscht, das Ereignis „Druck abgebrochen“ zeigte noch auf diese Zeile. Der Fremdschlüssel hat den ganzen Watcher-Tick zurückgerollt, der Abbruch kam nie ins Protokoll, und der neue Druck hat dieselbe Zeile weiterbenutzt. Das Ereignis hängt sich an den überlebenden Lauf. Wechselt die Datei, wird der offene Lauf geschlossen statt umbenannt. Ein Live-Lauf einer anderen Datei wird nicht mehr übernommen.
+- **Spulenwechsel:** Nach Filamentpause kein vorzeitiger Spulenabzug mehr (`watcher_resume`). Beim Zurücknehmen eines Abzugs wird der letzte Abschnitt wieder geöffnet; der Messwert wird anteilig nach mm verteilt. Beim Einlegen während des Drucks entsteht der erste Abschnitt auch dann (0→jetzt), wenn die alte Rolle schon im Regal ist oder ACE ohne Start-Abschnitt lief. Fallback slot-genau (Platz / ACE-Map / letzter Abschnitt). ACE-Start öffnet Abschnitte für gemappte Plätze mit Spule — ohne Wechsel bleibt Anteil-Split.
+
+### Geändert
+
+- **systemd:** `TimeoutStopSec=20` und `KillMode=mixed`, damit ein hängender Stopp nicht 90 s blockiert.
+- **Orca:** Anleitung und Empfehlung zeigen auf Grotti am Pi (`http://10.10.1.41:8770/`), nicht mehr lokal.
+- **Dateien:** Unveränderte Watch-Dateien werden beim Sync nur per Größe/mtime geprüft, nicht erneut geöffnet. `ace_trailer` liegt in der Datenbank; die Dateiliste öffnet die Datei nur noch einmal, wenn der Wert fehlt. Wand zeigt Drucker sofort, die Bibliothek lädt im Hintergrund. Pi-Paket: `http_threads` 8.
+- **3D-Pfad:** Ungespeicherte Bahnen werden nacheinander gebaut, nicht parallel. `http_threads` begrenzt die Request-Threads. Sonst liest die Vorschau mehrere G-codes gleichzeitig und füllt auf einem Pi mit 2 GB den Speicher.
+- **UI:** Wärmeres Orange-Licht (App und Login), Warten-Status in Amber statt Knopf-Orange, Druckerwand mit heller Kartenkante, größerer Prozentzahl und atmendem Druck-Streifen.

+
+## Marlin-Dienst
+
+Grotti startet ihn selbst, sobald ein i3 oder Tenlog in der Liste steht. Lauscht er schon, bleibt der Prozess: Neustart und Absturz von Grotti schicken keinen Abbruch und öffnen die Leitung nicht neu. Grotti beendet den Dienst nicht.
+
+Lokal ist das ein eigener Prozess (`python -m grotti.marlin_daemon`, Log `data/marlin-dienst.log`). Auf dem Pi ist es die Unit `grotti-marlin.service`, außerhalb von `grotti.service`, damit ein `systemctl restart grotti` den Druck nicht mitnimmt.
+
+Port `GROTTI_MARLIN_PORT` (8771). `pyserial` öffnet die Leitung. Der Host des Druckers ist die Schnittstelle, Baud optional dahinter: `COM5`, `COM5@250000`, `/dev/ttyUSB0`. In den Einstellungen eintragen, Familie Anycubic i3 oder Tenlog.
+
+Beim ersten Öffnen setzt USB den Drucker zurück (DTR). Danach bleibt der Port im Dienst.
+
+Start pro Auftrag, Feld `marlin_mode` am Senden:
+
+- `stream` — Zeile für Zeile, jede Zeile wartet auf `ok`. Fortschritt ist die Dateiposition. Bricht die Leitung ab, stirbt der Druck.
+- `sd` — Datei per `M28`/`M29` auf die Karte (Name 8.3, `TEIL.GCO`), dann `M23`/`M24`. Der Drucker druckt allein, der Dienst fragt `M27` und `M105`.
+
+`T0` und `T1` gehen unverändert in den Strom. Tenlog (`family: tenlog`) meldet zwei Köpfe unter `tools`, die Wand zeigt beide Temperaturen. `slots` bleibt leer, ein Start verlangt keine ACE-Zuordnung. Pause, Weiter und Abbruch gehen über die Wand. Heizen, Speed und Plätze nicht: das steht im G-code. Pause im Strom hält die nächsten Zeilen an, auf der Karte ist es `M25`/`M24`. Abbruch schaltet die Heizungen aus; auf der Karte zusätzlich `M524`.
+
+Die Warteschlange „wenn frei“ übergibt den Modus noch nicht, dort gilt Strom.
