Upgrade 1: Improving the Bed
One of the most critical upgrades for the Tevo Tarantula is improving its bed leveling system. A properly leveled bed ensures that the first layer adheres correctly, which is essential for successful prints. Upgrading the bed can significantly reduce print failures and improve overall print quality. Several options are available, ranging from simple manual adjustments to more advanced automated systems. This upgrade is often the first step in optimizing the printer for better performance.
Why Bed Leveling is Crucial
Bed leveling is the foundation of successful 3D printing. If the bed is not level, the distance between the nozzle and the bed will vary across the printing surface. This can lead to several problems, including poor first-layer adhesion, warping, and nozzle crashes. An uneven bed causes the filament to be squished too much in some areas and not enough in others, leading to inconsistent layer adhesion and ultimately, print failure. Proper bed leveling guarantees a consistent distance between the nozzle and the bed, which is essential for producing high-quality prints.
Upgrade Options for Bed Leveling
There are various options to improve the bed leveling process on your Tevo Tarantula. These upgrades can range from simple adjustments to more complex automated systems. The choice of upgrade will depend on your budget, technical skills, and desired level of convenience. The goal is to ensure a consistently level bed surface, thereby eliminating many common print problems. The following are two common upgrades that can significantly improve the performance of your Tevo Tarantula.
Manual Bed Leveling
Manual bed leveling involves adjusting the bed height using the leveling screws located at each corner of the bed. This method requires patience and precision, as you must adjust the screws until the nozzle is the correct distance from the bed across the entire surface. This can be achieved by using a piece of paper to gauge the distance between the nozzle and the bed. Although more time-consuming, manual bed leveling is a cost-effective solution that can provide accurate results with practice. However, it requires regular checks and adjustments, especially after printing multiple models.
Auto Bed Leveling (ABL) Systems
Auto Bed Leveling (ABL) systems automate the bed leveling process, making it significantly easier and more accurate. These systems typically use a sensor to measure the distance between the nozzle and the bed at multiple points. The printer’s firmware then uses this data to compensate for any bed imperfections during printing. This technology eliminates the need for manual adjustments and ensures a perfectly level first layer every time. There are different types of ABL systems, including inductive, capacitive, and BLTouch sensors. Installing an ABL system drastically reduces the likelihood of failed prints due to bed leveling issues. Consider installing an auto-bed-leveling system for better printing results.
Upgrade 2: Enhancing the Extruder
The stock extruder on the Tevo Tarantula, while functional, can be a source of frustration for some users. Upgrading the extruder can improve filament feeding, reduce jams, and allow for printing with a wider range of materials. Several options are available, each with its advantages and disadvantages. This upgrade can significantly enhance the reliability and versatility of your 3D printer.
Stock Extruder Design and its Drawbacks
The stock extruder on the Tevo Tarantula is usually a Bowden-style extruder, which means the extruder motor is mounted on the frame, and the filament is fed through a PTFE tube to the hot end. This design can have several drawbacks, including a longer filament path, which can lead to more retraction issues and filament jams, especially with flexible materials. Furthermore, the stock extruder may not provide enough force to consistently feed the filament, particularly at higher printing speeds. These limitations can affect print quality and reliability.
Upgrading to a Direct Drive Extruder
A direct drive extruder mounts the extruder motor directly on the hot end, eliminating the PTFE tube and significantly reducing the distance the filament needs to travel. This design offers several advantages, including more precise filament control, reduced retraction issues, and the ability to print with a wider range of materials, including flexible filaments. While a direct drive setup may add weight to the print head, the benefits in terms of print quality and reliability often outweigh the drawbacks.
Benefits of Direct Drive
Direct drive extruders offer several key advantages. They provide better control over filament flow, which leads to improved print quality and fewer issues like stringing and oozing. The shorter filament path allows for faster retractions and more precise movements, improving the accuracy of fine details. Direct drive extruders are particularly well-suited for printing with flexible filaments, as they provide better grip and prevent filament buckling. This upgrade will surely improve your prints.
Considerations for Direct Drive
When upgrading to a direct drive extruder, there are a few factors to consider. The added weight on the print head may require adjustments to the printer’s settings, such as acceleration and jerk values. You may also need to adjust the Z-offset to compensate for the change in the position of the nozzle. Ensure that the direct drive setup is compatible with your hot end and that you have sufficient cooling for the extruder motor. This upgrade requires planning to ensure a good fit.
