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>

Cornering
Cornering is a critical aspect of 3D printing that affects the quality and accuracy of prints. It refers to how the printer handles changes in direction during movement, particularly at corners and curves. Proper cornering settings can help reduce artifacts like ringing, ghosting, and overshooting, leading to cleaner and more precise prints.

WIP... TODO: Jerk calibration not implemented yet.
Junction Deviation
Junction Deviation is the default method for controlling cornering speed in MarlinFW (Marlin2) printers. Higher values result in more aggressive cornering speeds, while lower values produce smoother, more controlled cornering. The default value in Marlin is typically set to 0.08mm, which may be too high for some printers, potentially causing ringing. Consider lowering this value to reduce ringing, but avoid setting it too low, as this could lead to excessively slow cornering speeds.
-
Pre-requisites:
- Check if your printer has Junction Deviation enabled. You can do this by sending the command
M503to your printer and looking for the lineJunction deviation: 0.25. - In OrcaSlicer, set:
- Acceleration high enough to trigger ringing (e.g., 2000 mm/s²).
- Speed high enough to trigger ringing (e.g., 100 mm/s).
- Use an opaque, high-gloss filament to make the ringing more visible.
- Check if your printer has Junction Deviation enabled. You can do this by sending the command
-
You need to print the Junction Deviation test.
- Measure the X and Y heights and read the frequency set at that point in Orca Slicer.
- It’s very likely that you’ll need to set values lower than 0.08 mm, as shown in the previous example. To determine a more accurate maximum JD value, you can print a new calibration tower with a maximum value set at the point where the corners start losing sharpness.
- Print the second Junction Deviation test with the new maximum value.
- Measure the X and Y heights and read the frequency set at that point in Orca Slicer.
-
Save the settings
- Set your Maximun Junction Deviation value in [Printer settings/Motion ability/Jerk limitation].
- Use the following G-code to set the mm:
M205 J#JunctionDeviationValue M500Example
M205 J0.012 M500- Recompile your MarlinFW
- In Configuration.h uncomment and set:
#define JUNCTION_DEVIATION_MM 0.012 // (mm) Distance from real junction edge- Check Classic Jerk is disabled (commented).
//#define CLASSIC_JERK
