The Voron 2.4 is available as standard in the 250, 300 and 350 versions, which have build volumes of 250×250×250 mm (~15 L), 300×300×300 mm (~27 L) and 350×350×350 mm (~42 L), respectively. It features a closed build chamber, which provides stable temperatures that are favorable for certain types of
3D printing filament, reduces noise, and allows for controlled exhaust emissions (
HEPA filter extensions are available). The CoreXY design results in less moving mass, allowing for higher accelerations and speeds. The belt is based on the CoreXY pattern, but with the belts stacked on top of each other and without the crossover found in some other CoreXY designs, which allows for favorable motor placement. In other words, the 2.4 model has a stationary print plate and separate belts for moving the print head along the z-axis, while most other CoreXY printers on the other hand have a fixed gantry and a print plate that moves vertically with
lead screws. A stationary print plate gives the possibility to use a heavier print plate (for example of thick steel instead of thin aluminium) that warps less when heated. It also gives a more space efficient frame, and makes it easier to calibrate the print to be parallel with the build plate (less need for bed mesh trimming). A disadvantage is that the z-axis may sag when the printer is not in use, but it shall straighten itself again when the printer is turned on. All movement control is done with
Klipper software on a
Raspberry Pi, which provides great flexibility and extensibility through various parameters that can be programmed in a configuration file. The printer has the option of automatic calibration to compensate for unevenness in the build plate.
Input shaping was introduced in 3D printers by Klipper in 2020, and is a standard feature on Voron. == Construction and operation ==
