The best slicer settings profile for Ender 3 V3 is the stock 0.20mm Standard @Creality Ender3V3 0.4 nozzle process preset that OrcaSlicer ships for the Creality Ender-3 V3, left mostly as shipped, paired with a filament preset you have recalibrated yourself. The walls, accelerations and first layer are sound. The weak points are on the filament side: a generic 14 mm³/s volumetric cap, an uncalibrated flow ratio, and pressure advance switched off.
For PLA on the stock 0.4 mm nozzle, that means four changes in order: temperature, flow ratio, pressure advance, and a volumetric limit measured on your own spool. Creality Print, the slicer Creality specifies for the machine, is forked from OrcaSlicer, so most setting names carry over.
Which Ender-3 V3 profile should you load?
Load the preset that matches your exact model, because three different printers share the Ender-3 V3 name. The CoreXZ Ender-3 V3 runs Creality OS, which 3DPrint.com describes as Klipper-based. The V3 SE runs Marlin, and the V3 KE runs Klipper at far lower acceleration limits.
OrcaSlicer’s 0.4 mm machine presets show the split:
| Model | G-code flavor | Max X speed | Max X accel | Default retraction |
|---|---|---|---|---|
| Ender-3 V3 (CoreXZ) | Klipper | 600 mm/s | 20,000 mm/s² (Y: 5,000) | 0.6 mm at 40 mm/s |
| Ender-3 V3 KE | Klipper | 500 mm/s | 8,000 mm/s² | 0.5 mm at 30 mm/s |
| Ender-3 V3 SE | Marlin 2 | 250 mm/s | 2,500 mm/s² | 1.2 mm at 40 mm/s |
The CoreXZ preset’s start G-code is a single Klipper START_PRINT macro call carrying the nozzle and bed temperatures. Marlin on an SE has no such macro, so cross-loading profiles is not a cosmetic mistake. Everything below applies to the CoreXZ V3 with its stock 0.4 mm hardened-steel nozzle; Orca also ships 0.6 and 0.8 mm variants, and the trade-offs are covered in the nozzle size and layer height guide.
What does the stock 0.20 mm Standard profile set?
It sets 0.20 mm layers, three walls, three top and three bottom layers, and 15% crosshatch infill. Motion is aggressive on paper: 200 mm/s outer walls, 300 mm/s inner walls and 500 mm/s sparse infill, with 5,000 mm/s² on walls and top surfaces and 12,000 mm/s² elsewhere. The first layer is deliberately slow.
Key values from the process preset on GitHub:
| Setting | Stock value |
|---|---|
| Line width (outer / inner / infill / first layer) | 0.42 / 0.45 / 0.45 / 0.50 mm |
| Walls | 3, single wall on top surfaces |
| Top / bottom shells | 3 layers (0.6 mm minimum top) / 3 layers |
| Outer / inner wall | 200 / 300 mm/s at 5,000 mm/s² |
| Sparse infill | 15% crosshatch at 500 mm/s |
| Travel | 500 mm/s at 12,000 mm/s² |
| First layer | 0.20 mm at 60 mm/s, 500 mm/s² |
| Elephant-foot compensation | 0.15 mm |
| Seam | Aligned, conditional scarf seam on |
The 5,000 mm/s² wall acceleration matches the machine preset’s Y limit, and Y is the axis carrying the bed. Pushing wall acceleration toward 12,000 costs surface quality twice: more ringing, and more input-shaper smoothing, which Klipper’s resonance compensation docs say grows with acceleration. Leave it; the reasoning is in print speed vs quality with input shaping.
The speed you set is not the speed you get
The Generic PLA @Ender-3 V3 filament preset caps max volumetric speed at 14 mm³/s, and the slicer slows any feature that would exceed it. Approximate flow is line width × layer height × speed:
- Outer wall: 0.42 × 0.20 × 200 = 16.8 mm³/s, so roughly 165 mm/s after the cap.
- Inner wall: 0.45 × 0.20 × 300 = 27 mm³/s, so roughly 155 mm/s.
- Sparse infill: 0.45 × 0.20 × 500 = 45 mm³/s, so roughly 155 mm/s too.
The “500 mm/s” profile prints generic PLA at about 155 to 165 mm/s on nearly every feature. The CR-PLA preset allows 18 mm³/s, lifting walls and infill to roughly 200 mm/s; Generic PETG’s 8 mm³/s holds it near 90 mm/s. The hotend is not what limits you, since 3DPrint.com reports Creality’s claim of up to 32 mm³/s. The rectangle maths slightly overstates flow because the slicer models rounded line edges, so confirm the real figures in Preview with the flow colour scheme, as the OrcaSlicer volumetric speed page suggests.
On the V3, filament max volumetric speed is the throttle. The speed fields are ceilings you rarely reach.
Recommended PLA settings for the Ender-3 V3
Keep the process preset’s geometry and motion, and retune the filament preset. These are starting points for a typical 1.75 mm PLA spool:
| Setting | Stock (Generic PLA) | Tuned starting point |
|---|---|---|
| Nozzle temperature | 220 °C (preset range 190–240 °C) | Your temperature tower result |
| Bed temperature | 65 °C | Keep |
| Flow ratio | 0.98 | Your flow-ratio test result |
| Max volumetric speed | 14 mm³/s | Measured value minus 10–20% |
| Pressure advance | Off (0.02 stored, not sent) | Calibrated value, enabled |
| Part cooling fan | 60–80% | Keep |
| Retraction | 0.6 mm at 40 mm/s, 0.4 mm Z-hop | Change only after a retraction tower |
| Walls | 3 | 4 for load-bearing parts |
Temperature. CR-PLA’s preset runs 230 °C against Generic PLA’s 220 °C, so one number does not fit every spool. Print a temperature tower and log the brand and batch with the result.
Flow ratio. OrcaSlicer’s flow ratio calibration YOLO test spans −0.05 to +0.05 in 0.01 steps; add the modifier on the smoothest block to the current ratio. Select the right filament preset first, since the test works from its ratio. Dimensional checks are in flow rate calibration and dimensional accuracy.
Pressure advance. Both Ender-3 V3 filament presets ship with pressure advance unticked, so the slicer sends nothing and the printer uses its firmware value. Run the direct-drive variant of Orca’s pressure advance test; the tower method does not depend on first-layer quality. Enter the result and tick the enable box. Reading the pattern is covered in the pressure advance calibration guide.
Volumetric speed. Orca’s default test runs 5 to 20 mm³/s in 0.5 steps, and the limit is start + (failure height × step). The wiki’s own example, failure at 19 mm, gives 14.5 mm³/s, and it advises setting 10 to 20 percent lower. That lands at 12 to 13 mm³/s, below the stock 14, so do not assume the shipped cap is conservative.
Walls. For load-bearing parts, add a fourth wall before raising infill density. Crosshatch at 15% suits display parts and keeps the speed.
PETG settings for the Ender-3 V3
The Generic PETG @Ender-3 V3 preset is a reasonable base: 235 °C nozzle (range 220–270 °C), 70 °C bed, 0.95 flow ratio, 8 mm³/s cap, 80–90% fan, and 1.2 mm retraction at 30 mm/s. Use the same 0.20 mm process preset; the volumetric cap already slows PETG, so a separate slow process adds nothing.
PETG is more prone to stringing than PLA. Run the volumetric test before raising the cap, and tune retraction with a tower using the method in how to fix stringing on 3D prints. For choosing between the two materials, the PETG vs PLA strength comparison covers what the datasheets support.
OrcaSlicer or Creality Print?
Use OrcaSlicer if you plan to calibrate: its Calibration menu generates every test above, and its Ender-3 V3 presets are readable on GitHub. Creality Print is the slicer Creality specifies, the natural pairing with the printer’s Creality Cloud and Wi-Fi transfer, and its README confirms the OrcaSlicer fork under AGPL-3.0.
In either one, save the tuned filament preset as a user preset named after the spool. System presets change when the slicer updates; your calibration should not.
In what order should you tune it?
Tune in this order: printer self-check, temperature, flow ratio, pressure advance, max volumetric speed, then retraction. Each step changes the conditions the next one measures, so working out of order wastes filament and gives numbers you cannot trust.
Run the self-check from the touchscreen first so auto-levelling and input-shaper results are current; a pressure advance line test read on a poor first layer is meaningless. Temperature sets melt viscosity, which flow and pressure advance both depend on. Pressure advance reduces the retraction a direct-drive extruder needs, so retraction comes last. The full reasoning is in 3D printer calibration order.
How to verify the tuned profile
Print a 20 mm calibration cube and one sharp-cornered part at your final settings, not test-print speeds. Pass criteria:
- Corners neither bulge nor gap at the seam (pressure advance).
- Top surface closed with no ridges between lines (flow ratio).
- No echo trailing sharp features on X or Y faces (acceleration and input shaping).
- X and Y within the ±0.2 mm accuracy Creality specifies, measured away from the seam.
- In Preview’s flow colour scheme, the cap binds only where you expect.
If all five pass, export the filament preset with the spool batch in its name. A spool from a different batch gets a fresh flow ratio and pressure advance check.
FAQ
What is the max volumetric speed for the Ender-3 V3?
OrcaSlicer’s Ender-3 V3 presets cap Generic PLA at 14 mm³/s, CR-PLA at 18 mm³/s and Generic PETG at 8 mm³/s. Creality claims up to 32 mm³/s for the hotend, but that is a hardware ceiling, not a per-spool guarantee. Run OrcaSlicer’s volumetric speed test and set the result 10 to 20 percent lower.
Does the Ender-3 V3 use Klipper?
Yes. The CoreXZ Ender-3 V3 runs Creality OS, which is based on Klipper, and OrcaSlicer’s machine preset uses the Klipper G-code flavor with a START_PRINT macro. The Ender-3 V3 SE is different: it runs Marlin, so its profiles, start G-code and acceleration limits are not interchangeable with the V3.
What retraction settings should I use on the Ender-3 V3?
Start with the stock values: 0.6 mm at 40 mm/s for PLA with a 0.4 mm Z-hop, and 1.2 mm at 30 mm/s for PETG. The V3 is direct drive, so short retractions are normal. Change them only after calibrating pressure advance and running a retraction tower, because pressure advance reduces the retraction needed.
Can I use the Ender-3 V3 KE profile on the Ender-3 V3?
No. The Ender-3 V3 KE preset caps acceleration at 8,000 mm/s² and speed at 500 mm/s, defaults to 0.5 mm retraction at 30 mm/s, and pairs with KE-specific process and filament presets. Select “Creality Ender-3 V3” with the matching 0.4, 0.6 or 0.8 mm nozzle in the printer list instead.
