Added new images for adaptive cubic and 2D honeycomb infill patterns. Updated strength_settings_infill.md to revise infill strength values, descriptions, and remove references to deleted images. Introduced documentation for 2D honeycomb infill and made minor corrections and clarifications throughout. * Revise infill pattern documentation and add comparison table Updated strength_settings_infill.md to clarify infill density calculation, add a comprehensive comparison table of infill patterns, and standardize terminology for strength and print time. Expanded pattern descriptions to use qualitative strength ratings instead of numeric values. Updated infill_desc_calculator.xlsx to reflect these changes. * Indentation in code examples Adjusted the indentation of code blocks in the cornering calibration documentation for clarity and consistency with the rest of the document. * Update 3D Honeycomb infill strength ratings Adjusted the horizontal strength rating for 3D Honeycomb infill from 'Normal' to 'Normal-High' in the strength settings documentation and table. Updated the infill_desc_calculator.xlsx file to reflect these changes. * Formatting and fix in ERS documentation Updated headings to use consistent Markdown syntax, improved clarity in explanations, and reworded references for better readability. * Fix wall generator doc link and filename Updated the Home.md to reference the correct 'quality_settings_wall_generator' section and renamed the corresponding documentation file for consistency. --------- Co-authored-by: Rodrigo <162915171+RF47@users.noreply.github.com>
