If you're looking for the best OrcaSlicer PLA settings for your Elegoo printer, this baseline profile delivers the fundamentals that matter most. Designed specifically for Elegoo filament on the Centuri Carbon 2, this profile balances print quality, reliability, and reasonable print speed. Whether you're printing functional parts or prototypes, these OrcaSlicer PLA settings provide a solid foundation that gets the important parameters right from the start.
This profile focuses on the core tuning areas that directly impact print success. The nozzle temperature is set to 205°C with an initial layer at 210°C, giving the filament enough heat for proper flow without excessive oozing. Bed temperature is held at 55°C on the cool plate, which provides reliable adhesion while minimizing warping—a common concern with PLA.
Cooling is managed intelligently through a two-stage approach. The first layer runs with reduced fan speed to ensure solid bed adhesion, then full cooling engages immediately after. Pressure advance is enabled at 0.028, which sharpens corners and improves wall quality by compensating for nozzle pressure dynamics. The maximum volumetric flow is capped at 25 mm³/s, preventing extrusion inconsistencies at higher speeds.
The Smart Grille is configured for open mode, which is optimal for PLA cooling. These settings work together to produce consistent, reliable prints without requiring extensive tuning.
Nozzle Temperature: The 205°C standard temperature with a 210°C initial layer ensures proper filament flow during the critical first layer while avoiding heat-related defects. This range keeps the filament in the optimal viscosity window for Elegoo PLA.
Bed Temperature: 55°C on the cool plate provides sufficient adhesion without the risk of warping or bed sticking that can occur at higher temperatures. This is particularly important for larger prints.
Pressure Advance: Set to 0.028, this compensates for the delay between extrusion commands and actual filament flow. The result is sharper corners, cleaner walls, and better dimensional accuracy—especially noticeable on parts with fine details.
Cooling Strategy: Full fan speed (100%) engages after the first layer, maximizing cooling for layer-to-layer adhesion and surface finish. The overhang fan threshold at 50% ensures aggressive cooling where it matters most.
Volumetric Flow Limit: Capped at 25 mm³/s, this prevents the extruder from being asked to push more material than it can reliably handle, reducing the risk of under-extrusion and inconsistent prints.
Can I use this profile with other PLA brands? This profile is optimized for Elegoo PLA, but it can serve as a starting point for other brands. If you experience under-extrusion or over-extrusion, adjust the flow ratio (currently 0.97) in small increments of 0.02.
What should I do if my prints are warping? Warping typically indicates bed temperature is too high or cooling is insufficient. Try reducing bed temperature to 50°C or ensure the Smart Grille is in open mode for better airflow.
Is pressure advance necessary? Pressure advance improves print quality noticeably, especially on parts with sharp corners and thin walls. If you're new to it, keep the current value of 0.028 and observe the improvement in wall consistency.
Can I print faster with these settings? This profile prioritizes reliability over speed. If you want to increase print speed, do so gradually and monitor the first few layers. You may need to increase nozzle temperature slightly if you see under-extrusion.
Why is the first layer fan speed reduced? Reducing fan speed during the first layer allows the plastic to bond more securely to the bed. Once the part is anchored, full cooling improves layer adhesion and surface finish for subsequent layers.
Load this profile into OrcaSlicer and start with a small test print to verify that your specific printer setup matches these baseline settings. Minor adjustments may be needed based on your nozzle condition, filament batch, or environmental factors like ambient temperature.
