Grotti 2.2.6: Wand-Vorschau, dichterer 3D-Pfad, ASCII-Dateinamen.

Kacheln zeigen Moonraker-Thumbnails; Toolpath-Thinning behält ganze Schichten; Nicht-ASCII-Namen vermeiden 10115 beim Senden.

 ## [Unreleased]
 
+### Neu
+
+- Wand-Kacheln zeigen das Druck-Vorschaubild (Moonraker-Thumbnail) in der Job-Zeile.
+
+### Behoben
+
+- 3D-Pfad wirkte gesprenkelt: Ausdünnen behält ganze Schichten dicht (statt Stichproben entlang der Bahn); keine Parallel-Offsets.
+- Toolpath-API mit `Cache-Control: no-store`, damit der Browser keinen alten Pfad behält.
+- Senden: Dateinamen mit Nicht-ASCII (z. B. CJK) werden für Moonraker/Rinkhals auf ASCII normalisiert — sonst Fehler 10115 „gcode … not found“.
+
+## [2.2.2] – 2026-10-15
+
+### Behoben
+
+- 3D-Pfad: bei großen G-codes zerbrach das Ausdünnen die Segment-Paare — Viewer zeigte nur Objekt-Umrisse, keinen Druckfortschritt (grün/grau).

 ## ACE / `.acm`
 
 Drucker mit ACE/MMU-Plätzen (`mmu.gate_color` / `gate_material`, Grotti-`slots`) brauchen vor `print/start` eine Sidecar-Datei `*.gcode.acm`. In der UI unter Optionen → ACE-Zuordnung (Datei-Farbe → Platz). Ohne passende `.acm` lehnt der Drucker oft mit „cannot parse the file“ ab — Details hier, nicht als Banner in der App:
