High-speed printing places high demands on both the hardware and firmware of a 3D printer. To achieve the best results, precise configuration and upgrading of components is required. In this article, we explain in detail how to optimize your 3D printer hardware and firmware to maximize print speed and quality.
Hardware optimization for high-speed printing
Motion systems: The foundation for fast print speeds
When choosing the right motion systems for high-speed printers, the components used play a crucial role. There are two main options that can improve print speed and accuracy:
-
Linear bearings vs. linear rails
Linear bearings, also known as linear guides, offer a cost-effective solution for motion control. They minimize friction and require only minimal maintenance, such as regular lubrication and cleaning. In comparison, linear rails are more expensive but provide significantly higher stability and precision. These components are especially useful in printers with CoreXY or CoreXZ systems, like the Voron Switchwire. They help reduce friction and increase movement speed, making the printer more efficient. -
Reducing the weight of moving parts
A common problem with print speed is vibrations caused by heavy moving parts. Replacing glass beds with lighter PEI sheets can reduce vibrations and improve print quality. This is especially important for bed sliders that move on the Z-axis, as in some Ender 5 series printers.
Optimization of the hotend and extruder
The hotend and extruder are other critical components for high-speed printing. A direct-drive system with a large stepper motor can negatively affect print speed. Instead, we recommend using lighter extruders, such as the Bondtech LGX Lite, or pancake stepper motors to reduce weight and minimize vibrations. Alternatively, Bowden cables are advantageous due to their low weight for fast print movements.
Firmware optimization for high-speed printers
Klipper firmware: The powerful solution
Klipper firmware has proven to be extremely powerful for high-speed printers. By using a Raspberry Pi as the computing center, you can benefit from higher processing power and advanced features. Klipper supports features like Input Shaping, which compensates for a printer's resonance frequencies and thus reduces unwanted vibrations.
Advantages of Klipper:
- Advanced features: Klipper enables integration of new features like Pressure Advance.
- Easy configuration: Configuration is done through compact text files, greatly simplifying customization.
- Remote monitoring: With a Raspberry Pi, you can connect a webcam and monitor your print via the web interface.
Challenges with Klipper:
- Cost and availability: Raspberry Pis are expensive and hard to get due to current supply shortages.
- Setup effort: Installing and configuring a Raspberry Pi with Klipper can be complex and may not be suitable for beginners.
Alternatives to Klipper firmware
If a Raspberry Pi is not available or ideal for your situation, there are other options:
-
Manta CB1 from BIGTREETECH
This board combines a mainboard with a secondary board that offers similar functions to a Raspberry Pi. Setup is cheaper than a Raspberry Pi but still requires extensive configuration steps. -
Klipper pads like the Creality Sonic Pad and the FLSUN Speeder Pad
These pads offer preconfigured profiles for numerous printer models and greatly simplify setup. For example, the Creality Sonic Pad supports printers with STM32F104 chips and provides a user-friendly interface for firmware configuration. -
Marlin firmware
Marlin firmware is a popular alternative available for many printer mainboards. Although setup can be more complex, numerous online resources and preconfigured profiles provide support. For customizing Marlin, Visual Studio Code along with PlatformIO is recommended.
Conclusion
Optimizing hardware and firmware is crucial for success in high-speed printing. By using high-quality motion systems, reducing the weight of moving parts, and choosing the right firmware, you can significantly improve print speed and quality. The choice between Klipper firmware, special pads, or Marlin depends on your specific requirements and available budget. With the right configuration and suitable components, you can maximize your 3D printer's performance and achieve outstanding print results.
