Precision
This section covers the settings that affect the precision of your prints. These settings can help you achieve better dimensional accuracy, reduce artifacts, and improve overall print quality.
- Slice gap closing radius
- Resolution
- Arc fitting
- X-Y Compensation
- Elephant foot compensation
- Precise wall
- Precise Z Height
- Polyholes
Slice gap closing radius
Cracks smaller than 2x gap closing radiusCracks smaller than 2x gap closing radius are being filled during the triangle mesh slicing. The gap closing operation may reduce the final print resolution, therefore it is advisable to keep the value reasonably low.
Resolution
The G-code path is generated after simplifying the contour of models to avoid too many points and G-code lines. Smaller value means higher resolution and more time to slice.
Arc fitting
Enable this to get a G-code file which has G2 and G3 moves.
After a model is sliced this feature will replace straight line segments with arcs where possible. This is particularly useful for curved surfaces, as it allows the printer to move in a more fluid manner, reducing the number of G-code commands and improving the overall print quality.
This will result in a smaller G-code file for the same model, as arcs are used instead of many short line segments. This can improve print quality and reduce printing time, especially for curved surfaces.
Important
This option is only available for machines that support G2 and G3 commands and may impact in CPU usage on the printer.
Note
Klipper machines, this option is recommended to be disabled. Klipper does not benefit from arc commands as these are split again into line segments by the firmware. This results in a reduction in surface quality as line segments are converted to arcs by the slicer and then back to line segments by the firmware.
X-Y Compensation
Used to compensate external dimensions of the model. With this option you can compensate material expansion or shrinkage, which can occur due to various factors such as the type of filament used, temperature fluctuations, or printer calibration issues.
Follow the Calibration Guide and Filament Tolerance Calibration to determine the correct value for your printer and filament combination.
Elephant foot compensation
This feature compensates for the "elephant foot" effect, which occurs when the first few layers of a print are wider than the rest due:
- Weight of the material above them.
- Thermal expansion of the material.
- Bed temperature being too high.
- Inaccurate bed height.
To mitigate this effect, OrcaSlicer allows you to specify a negative distance that will be applied to the first specified number of layers. This adjustment effectively reduces the width of the first few layers, helping to achieve a more accurate final print size.
Precise wall
The 'Precise Wall' is a distinctive feature introduced by OrcaSlicer, aimed at improving the dimensional accuracy of prints and minimizing layer inconsistencies by slightly increasing the spacing between the outer wall and the inner wall.
Technical explanation
Below is a technical explanation of how this feature works.
First, it's important to understand some basic concepts like flow, extrusion width, and space. Slic3r has an excellent document that covers these topics in detail. You can refer to this article.
Now, let's dive into the specifics. Slic3r and its forks, such as PrusaSlicer, SuperSlicer, and OrcaSlicer, assume that the extrusion path has an oval shape, which accounts for the overlaps. For example, if we set the wall width to 0.4mm and the layer height to 0.2mm, the combined thickness of two walls laid side by side is 0.714mm instead of 0.8mm due to the overlapping.

This approach enhances the strength of 3D-printed parts. However, it does have some side effects. For instance, when the inner-outer wall order is used, the outer wall can be pushed outside, leading to potential size inaccuracy and more layer inconsistency.
It's important to keep in mind that this approach to handling flow is specific to Slic3r and its forks. Other slicing software, such as Cura, assumes that the extrusion path is rectangular and, therefore, does not include overlapping. Two 0.4 mm walls will result in a 0.8 mm shell thickness in Cura.
OrcaSlicer adheres to Slic3r's approach to handling flow. To address the downsides mentioned earlier, OrcaSlicer introduced the 'Precise Wall' feature. When this feature is enabled in OrcaSlicer, the overlap between the outer wall and its adjacent inner wall is set to zero. This ensures that the overall strength of the printed part is unaffected, while the size accuracy and layer consistency are improved.
Precise Z Height
This feature ensures the accurate Z height of the model after slicing, even if the model height is not a multiple of the layer height.
For example, slicing a 20mm x 20mm x 20.1mm cube with a layer height of 0.2mm would typically result in a final height of 20.2mm due to the layer height increments.
By enabling this parameter, the layer height of the last five layers is adjusted so that the final sliced height matches the actual object height, resulting in an accurate 20.1mm (as shown in the picture).

Polyholes
A polyhole is a technique used in FFF 3D printing to improve the accuracy of circular holes. Instead of modeling a perfect circle, the hole is represented as a polygon with a reduced number of flat sides. This simplification forces the slicer to treat each segment as a straight line, which prints more reliably. By carefully choosing the number of sides and ensuring the polygon sits on the outer boundary of the hole, you can produce openings that more closely match the intended diameter.
