Creating a Custom Print Profile in Orca Slicer from Scratch

When you buy an off-brand filament with no Orca profile, or want settings tuned exactly to your spool, build a profile from scratch. Here's the full process.

Step 1 — Start from Closest Existing Profile

1. Open Orca Slicer → Filament settings tab
2. Find the closest match (e.g., Generic PLA if you have a PLA-based material)
3. Click Copy profile — give it a name (e.g., "eSun PLA+ White")

Step 2 — Set Basic Temperatures

Start conservative:

Step 3 — Run Calibrations In Order

Run these Orca Slicer calibration prints in sequence — each feeds into the next:

1. Temperature Tower — find optimal temp
2. Flow Rate — tune extrusion multiplier (target: 0.95–1.05)
3. Pressure Advance — tune PA value
4. Retraction — tune retraction distance

Step 4 — Tune Cooling

Step 5 — Save and Test

1. Print a 20mm calibration cube
2. Measure with calipers — should be 20.0 ± 0.2 mm
3. Adjust flow rate if off
4. Print a benchy or functional test part

Filament Notes Field

Use the Notes field in the profile to record:

• Purchase date / source
• Actual measured diameter
• Best settings found
• Any quirks
