The Voron 2.4 is built for speed, but speed doesn’t mean much if print quality takes a hit. A fast printer that spits out sloppy prints is useless. What makes the Voron 2.4 different is that it balances speed and precision better than most high-end DIY 3D printers out there.
Speed and Precision
Right out of the box, the Voron 2.4 is tuned to print at 120 mm/s, which is already fast compared to most consumer-grade printers that average 50–60 mm/s. But with some fine-tuning and a strong cooling setup, it can easily push beyond 250 mm/s while maintaining great accuracy.
A lot of that performance comes down to the CoreXY motion system.
Unlike Cartesian-style printers, where the bed moves on the Y-axis, CoreXY keeps the bed stationary on the Z-axis. In contrast, the printhead moves in both X and Y. This means less weight shifting around, allowing for higher speeds without losing precision.
Of course, speed isn’t the only factor. Accuracy is what really separates the Voron 2.4 from others in its class. The quad gantry leveling system keeps the bed perfectly level at all times. Because the frame is rock solid, there’s practically no flex or wobble, even during aggressive acceleration moves.
Ringing and ghosting are usually problems at high speeds, but the Voron 2.4 minimizes those issues thanks to input shaper calibration in Klipper firmware. More on that later, but the short version is that it actively reduces vibrations, so your prints stay sharp and clean.
Test Prints and Benchmark Results
To really test print quality, we ran a few standard benchmarks, starting with a 20 mm calibration cube. At 120 mm/s, the cube came out with sharp edges, consistent extrusion, and no visible artifacts. Even when we increased the speed up to 200 mm/s, the dimensions stayed accurate, and the surface finish was surprisingly smooth.
Next was the classic Benchy test, but we wanted to push things, so we ran it at 200 mm/s. Some printers would struggle with overhangs and fine details at that speed, but the Voron handled it well.
The cooling system kept up, preventing drooping on the front of the boat, and the text on the bottom was still legible. There was some slight ringing in the hull, but that was primarily due to our input shaper settings needing a final tweak.
We printed a Snorlax figure with small textures and sharp overhangs for a more detailed test.
At a layer height of 0.15 mm, the details were crisp, and the thin parts of the Pokemon were printed without issues. The Voron’s direct drive extruder played a big role here, keeping retraction settings dialed in so there was almost no stringing on the final product.
Layer consistency was another highlight. We ran a 200 mm tall tower to check for banding or shifts, but every layer was stacked perfectly. This is where the quad gantry system shines.
On a typical printer with a single Z lead screw, minor imperfections can build up over time. But because the Voron constantly adjusts itself, those issues are completely eliminated.
| Test Type | Result Highlights | Observations |
| Calibration Cube | 20.1×20.1 mm average dimensions | Excellent repeatability (<0.1 mm deviation) |
| Detailed Model | Exceptional resolution and minimal ringing | Input shaper tuning is crucial for the best results |
| Overhang & Bridge | Overhangs up to 65°; bridges up to 60 mm | Cooling and speed adjustments improve quality |
| Print Tower | Perfect layer consistency | The quad-gantry system keeps everything leveled |
Firmware, Tuning, and Calibration
The Voron 2.4 runs on Klipper firmware, which is what gives it such smooth motion and high-speed performance. Marlin handles everything on the printer’s mainboard, but Klipper offloads processing to a Raspberry Pi. With that extra power, it calculates movements faster and improves print quality.
Among Klipper’s best features is the input shaper. It measures vibrations and applies real-time corrections to keep prints sharp, even at high speeds. Running the input shaper calibration test takes some time, but the improvement is massive once it’s set up. Ghosting is reduced, corners stay sharp, and fine details print cleaner.
One other important setting is pressure advance. It fine-tunes extrusion to keep filament flow consistent during fast movements. Without it, you’ll see blobbing at corners where the extruder lags. When tuned correctly, the Voron 2.4 keeps extrusion smooth across accelerations and decelerations, preventing these issues.
To get the best performance from the Voron 2.4, these adjustments make a huge difference:
- Input Shaper Calibration: Reduces ringing and ghosting by compensating for vibrations.
- Pressure Advance: Keeps extrusion flow steady, preventing blobs at corners.
- Belt Tensioning: Ensures even movement in CoreXY systems to avoid skewed prints.
- Z Offset and First Layer Tuning: Proper Z height leads to strong bed adhesion and smooth first layers.
- PID Tuning: Stabilizes hotend and heated bed temperatures for consistent extrusion.
Then there’s belt tensioning. CoreXY printers rely on even belt tension to avoid skewed prints, and the Voron’s design makes it easy to get it right. You can use a printed belt tension meter or go-by feel, but either way, keeping the belts equally tight on both sides is key to accurate prints.
