MakerVault Wiki – Orca Slicer

This quick-reference guide will help you navigate OrcaSlicer, our versatile, open-source slicer used for the Creality Ender 3/CR-10, Prusa XL, Creality K1 and Centauri Carbon printers.

1. Interface Overview

OrcaSlicer uses a workflow-based design divided into four primary tabs at the top left of the screen:

  • Prepare: Where you import, position, and adjust settings for your models.
  • Preview: Used after slicing to inspect the G-code layer-by-layer before printing.
  • Device: A web-based interface to monitor your printer and live camera feed.
  • Project: Displays metadata and notes provided by the model’s creator.

2. The Slicing Sidebar

On the left side of the screen, you will find the three core sections that define your print:

  • Printer: Select your specific machine (e.g., Centauri Carbon 0.4 nozzle).
  • Filament: Choose your material; Generic PLA is the standard for most Maker Vault projects.
  • Process: This is where you adjust Layer Height, Infill, and Supports.

3. Model Manipulation

Once you import a model by dragging it onto the build plate, use these essential toolbar icons:

  • Move (M), Rotate (R), and Scale (S): Standard tools for positioning your model.
  • Lay on Face: Click this tool, then click a flat surface on your model to snap it perfectly to the bed.
  • Auto Orient: Automatically flips the model to its most stable printing position.

4. Slicing & Quality Checks

Click the green Slice Plate button in the top right to generate your instructions.

  • First Layer Inspection: Use the Layer Widget (vertical slider) to scroll to the very bottom; the first layer must look solid and continuous.
  • Steep Overhangs: Scroll through the layers to ensure no parts of the model are printing in mid-air.
  • “Mouse Ear” Brims: If your model has sharp corners prone to warping, use this Orca-exclusive feature to add circular “ears” for better adhesion.

5. Exporting & Printing

  • Network Printing: For the Creality K1 or Centauri machines, click Print to send the file via Wi-Fi (after it is paired via IP Address – found in system network settings)
  • SD Card Printing: For the Ender 3/CR-10, click the arrow next to the Print button and select Export G-code to save it to your SD card.
