📝 Walkthrough

Walkthrough

The print dialog now preserves filenames that contain directory separators. The thumbnail dialog derives the directory from the filename when available and uses the current path otherwise.

Changes

Print path handling

Layer / File(s)	Summary
Resolve filename paths `src/components/dialogs/StartPrintDialog.vue`, `src/components/dialogs/StartPrintDialogThumbnail.vue`	`startPrint` no longer prefixes the current path when the filename already contains `/`. Thumbnail path resolution now uses the filename directory and retains the current-path fallback.

Merge Risk: ⚪ Minimal · up to 73261

The change preserves subfolder paths when starting prints so dashboard-started G-code jobs can locate their thumbnails consistently. No current merge-blocking risk is identified.

It's nice to see a good and short PR description without long AI slop wall of text + with the line "created with the help of...". so did you add this line per hand? Normally this is just our identifier for ai slop...

I would just add in the file StartPrintDialogThumbnail.vue a one line comment to your 2 lines of code, when this case is possible, and add a 1 line comment to the next line (startsWith('/')) when this case is common. I think this would help, when the next one has to debug something here.

rescosta · 2026-09-02T19:16:34Z

Yeah, added it manually, your template asks to be explicit if AI helped. I used it to help investigate the bug, but I always run my own checks and tests manually. I'll add the requested comments now.

Add comment to clarify currentPathWithoutSlash logic.

meteyou · 2026-09-02T19:24:00Z

Ohh wow! I'm impressed, how deep you read our guide/description! This is not very common anymore!

I will review this pr tomorrow evening in detail (or at least Friday). Thx for contributing!

Document the basename fallback.

The existing comment explains path-qualified file.filename values, but it does not explain the currentPath fallback at Line 47. Add a comment that basename-only entries use currentPath and that its leading root slash is removed before URL construction. This clarifies when each path-handling case applies.
Proposed clarification
         // Status/History panel items already carry the full relative path in `filename`.
         const pos = this.file.filename.lastIndexOf('/')
         if (pos > 0) return this.file.filename.slice(0, pos)
+
+        // Basename-only entries use the current directory.
         if (this.currentPath.startsWith('/')) return this.currentPath.substring(1)
