New Features: ✅ Cookie Validation - Checks for PHPSESSID and cf_clearance before starting ✅ Test Mode - Run with --test flag to verify setup with one file first ✅ HTML Error Detection - Catches "enable Javascript" pages automatically ✅ Consecutive Failure Protection - Stops after 3 failures in a row (systematic error) ✅ Better Error Messages - Shows actual error content and troubleshooting steps ✅ Detailed Cookie Instructions - Step-by-step guide in the script header ✅ Early Exit - Won't download 157 error pages before noticing something's wrong Key Improvements: Test mode will catch the issue immediately: bash mmf_download_stl_files_enhanced.sh --test This downloads ONE file and validates it before proceeding. Cookie validation checks for cf_clearance - The "enable Javascript" error is almost always missing this Cloudflare token Shows the actual error page content so they can see what MyMiniFactory is returning Stops after 3 consecutive failures instead of downloading 157 HTML error pages Replace your script with this enhanced version Run [bash mmf_download_stl_files_enhanced.sh --test] first If test fails, follow the error message instructions to get a fresh cookie Make sure cookie is from a download request, not just browsing the site.
