Slicer Master Guide
Orca Slicer Calibration Workflow
A practical Orca Slicer calibration workflow for temperature, flow, pressure advance, retraction, max volumetric speed, supports, and final profile saving.
Use this guide in order. Start with the visible symptom, check the simple causes first, then change one setting or mechanical variable at a time. That makes the fix repeatable instead of lucky.
The correct workflow
- Start with a clean mechanical baseline. Slicer calibration cannot fix loose belts, dirty beds, or partial clogs.
- Create a duplicate printer/filament profile before editing. Never overwrite your only working profile.
- Tune one filament type at a time. PLA, PETG, TPU, and ASA should not share one generic profile.
Order of tests
- Temperature tower: find the cleanest layer bonding and surface finish range.
- Flow rate: correct over/under extrusion after temperature is close.
- Pressure advance: improve corner bulging and line starts/stops.
- Retraction: reduce stringing after drying and temperature are addressed.
- Max volumetric speed: find how fast the filament can actually melt.
- Tolerance/dimensional test: verify practical part fit.
Common mistakes
- Skipping filament drying and then over-tuning retraction.
- Using too much cooling on PETG and then blaming poor layer bonding on flow.
- Chasing perfect test towers while real models need slower outer walls or better support interface.
Good profile labels
| Item | Guidance |
|---|---|
| PLA Quality 0.20 | Normal detail, reliable speed, general use |
| PETG Strong 0.20 | Moderate speed, reduced fan, good layer bonding |
| TPU Slow 0.20 | Low speed, conservative retraction, flexible filament path |
| Mini Detail 0.12 | Fine detail, slower outer walls, smaller layer height |
After calibration
- Save the profile with material brand, nozzle size, and date.
- Export a backup profile after major changes.
- Keep notes of the exact spool that was tested.
