Built-in calibration wizards
OrcaSlicer's killer feature: under Calibration menu, you find prebuilt test prints for flow rate, pressure advance, max volumetric speed, temperature tower and retraction. Run these on a new printer or new filament to dial in settings in minutes.
Slice and print
- Drag an STL onto the build plate
- Adjust orientation if needed
- Set quality preset (0.2 mm standard, 0.16 fine, 0.28 draft)
- Slice and export G-code or send direct to networked printer
OrcaSlicer features worth knowing
- Object overlap warning: catches placement mistakes early
- Tree supports / organic supports: cleaner removal than grid supports
- Per-object settings: different infill or perimeters for different parts on one plate
- Pressure advance value per filament: tunable
- Klipper / Marlin / RepRap output compatibility
