Pressure Advance is a feature that compensates for the lag in filament pressure within the nozzle during acceleration and deceleration. It helps improve print quality by reducing issues like blobs, oozing, and inconsistent extrusion, especially at corners or during fast movements.

+### Pattern method
The pattern method is adapted from [Andrew Ellis' pattern method generator](https://ellis3dp.com/Pressure_Linear_Advance_Tool/), which was itself derived from the [Marlin pattern method](https://marlinfw.org/tools/lin_advance/k-factor.html) developed by [Sineos](https://github.com/Sineos/k-factorjs).
[Instructions for using and reading the pattern method](https://ellis3dp.com/Print-Tuning-Guide/articles/pressure_linear_advance/pattern_method.html) are provided in [Ellis' Print Tuning Guide](https://ellis3dp.com/Print-Tuning-Guide/), with only a few OrcaSlicer differences to note.

Next, Ellis' generator provided the ability to adjust specific printer, filament, and print profile settings. You can make these same changes in OrcaSlicer by adjusting the settings in the Prepare pane as you would with any other print. When you initiate the calibration test, Ellis' default settings are applied. A few things to note about these settings:
-1. Ellis specified line widths as a percent of filament diameter. The Orca pattern method does the same to provide its suggested defaults, making use of Ellis' percentages in combination with your specified nozzle diameter
-2. In terms of line width, the pattern only makes use of the `Default` and `First layer` widths
-3. In terms of speed, the pattern only uses the `First layer speed -> First layer` and `Other layers speed -> Outer wall` speeds
-4. The infill pattern beneath the numbers cannot be changed because it's not actually an infill pattern pulled from the settings. All of the pattern G-Code is custom written, so that "infill" is, effectively, hand-drawn and so not processed through the usual channels that would enable Orca to recognize it as infill

## Type
-This controls the generation of the brim at outer and/or inner side of models.
-Auto means the brim width is analyzed and calculated automatically.
+Controls how the brim is generated on a model's outer and/or inner sides.
+
+### Auto
+
+The Auto brim feature computes an optimal brim width by evaluating material properties, part geometry, printing speed, and thermal characteristics.
+
+- Model geometry
+ - Uses the model's bounding box to determine dimensions.
+ - Height-to-area ratio: `height/(width²*length)`.
+- Printing speed
+ - Higher maximum printing speeds generally increase the recommended brim width.
+- Thermal length
+ - Defined as the diagonal of the model's base.
+ - Reference thermal lengths (material-specific):
+ - ABS, PA-CF, PET-CF: 100
+ - PC: 40
+ - TPU: 1000
+- Material adhesion coefficient
+ - Default: 1
+ - PETG/PCTG: 2
+ - TPU: 0.5
+
+The computed brim width is capped at 20 mm and at 1.5× the thermal length. If the final width is under 5 mm and also less than 1.5× the thermal length, no brim will be generated (width = 0).
### Painted
-Painted will generate a brim only on painted areas of the model in the Prepare tab.
+Generates a brim only on areas that have been painted  in the Prepare tab .
### Outer
-Outer will generate a brim around the outer perimeter of the model.
-Easier to remove than inner brim but can affect the model's appearance if the brim is not removed cleanly.
+Creates a brim around the model's outer perimeter.
+Easier to remove than an inner brim, but may affect the model's appearance if not removed cleanly.
+
+
### Inner
-Inner will generate a brim around the inner perimeter of the model.
-More difficult to remove than outer brim and may close the model's inner details, but can hide where the brim was removed.
+Creates a brim around inner perimeters.
+More difficult to remove and less effective than an outer brim and may obscure fine inner details, but it can hide the brim removal seam.
+
+
+
+### Outer and Inner
+
+Creates a brim around both the outer and inner perimeters of the model.
+This approach combines the **disadvantages** of both brim types, making it more difficult to remove while potentially obscuring fine details but improving overall adhesion.
+
+
+
+> [!TIP]
+>> Consider using a [raft](support_settings_raft) on complex models/materials.
### Mouse Ears
-Mouse ears are small extensions added to the brim to help with adhesion and prevent warping.
-Usually this ears are added in the corners of objects to provide additional support and affect the model's appearance less than a full brim.
+Mouse ears are small, local brim extensions (typically placed near corners and sharp features) that improve bed adhesion and reduce warping while using less material than a full brim.
+The geometry analysis routine selects candidate locations based on the configured angle threshold and detection radius.
+
+
#### Ear max angle
-Maximum angle to let a brim ear appear.
-If set to 0, no brim will be created.
-If set to ~180, brim will be created on everything but straight sections.
+Angle threshold (degrees) used to decide where mouse ears may be placed:
+
+- 0° — disabled; no mouse ears are generated.
+- Between 0° and 180° — ears are created at features with local angles sharper (smaller) than the threshold.
+- 180° — ears are allowed on almost any non-straight feature.
#### Ear detection radius
-The geometry will be decimated before detecting sharp angles. This parameter indicates the minimum length of the deviation for the decimation.
+The geometry will be decimated before detecting sharp angles.
+This parameter indicates the minimum length of the deviation for the decimation.
0 to deactivate.
## Width
-Distance from model to the outermost brim line.
+Distance between the model and the outermost brim line.
+Increasing this value widens the brim, which can improve adhesion but increases material usage.
## Brim-Object Gap
-A gap between innermost brim line and object can make brim be removed more easily.
+Gap between the innermost brim line and the object.
+Increasing the gap makes the brim easier to remove but reduces its adhesion benefit; very large gaps may eliminate contact and negate the brim's purpose.

## Reduce Infill Retraction
-Don't retract when the travel is in infill area absolutely. That means the oozing can't been seen. This can reduce times of retraction for complex model and save printing time, but make slicing and G-code generating slower.
+When enabled, the slicer will skip retractions for travel moves that occur entirely inside infill regions. This reduces the number of retractions and can speed up printing for complex models, but it may increase oozing or stringing inside infill. Slicing time may also increase slightly.
+
+**Recommended** when internal cosmetic quality is not critical and you want fewer retractions.
## Add line number
-Enable this to add line number(Nx) at the beginning of each G-code line.
+Prefix each G-code line with a sequential line number (N1, N2, ...). Useful for debugging or tools that expect numbered G-code.
## Verbose G-code
-Enable this to get a commented G-code file, with each line explained by a descriptive text. If you print from SD card, the additional weight of the file could make your firmware slow down.
+Include descriptive comments for G-code lines and blocks to make the file human-readable and easier to debug.
+Verbose mode produces much larger files and may slow down SD-card printing on some printers.
## Label Objects
-Enable this to add comments into the G-code labeling print moves with what object they belong to, which is useful for the Octoprint CancelObject plugin. This settings is NOT compatible with Single Extruder Multi Material setup and Wipe into Object / Wipe into Infill.
+Insert comments that label moves with the object they belong to (object index or name). This is useful for integrations such as OctoPrint's Cancel Object plugin and for human inspection of the G-code.
+
+> [!IMPORTANT]
+> Object labelling is not compatible with Single-Extruder Multi-Material configurations or with "Wipe into Object" / "Wipe into Infill" strategies.
+> When those features are active, labels may be omitted.
## Exclude Objects
-Enable this option to add EXCLUDE OBJECT command in G-code.
+Add an `EXCLUDE OBJECT` marker or command in the exported G-code for objects flagged as excluded. This helps post-processors or custom scripts recognise excluded parts.
## Filename Format
-Users can define the project file name when exporting.
+Define a filename template for exported G-code. Templates may include tokens like project name, date, or other metadata to produce consistent and informative filenames on export.
+
+For example:
+
+```c++
+{input_filename_base}_{filament_type[initial_tool]}_{print_time}.gcode
+```
+
+Can be used to generate filenames like `OrcaCube_PLA_1h15m.gcode`.

## Single loop after first layer
-Limits the draft shield loops to one wall after the first layer. This is useful, on occasion, to conserve filament but may cause the draft shield to warp / crack.
+When enabled, limits the draft shield to a single wall after the first layer (i.e. only one loop is printed on subsequent shield layers). This reduces filament and print time but makes the shield less robust and more prone to warping or cracking.
