¶ Check the printing speed for different features
¶ Look Ahead
Look-Ahead is a technique commonly used in CNC machining and 3D printing to optimize and adjust the motion path and speed of the machine, thereby improving the efficiency and quality of machining or printing. Look-Ahead primarily works by analyzing upcoming path segments in advance and preemptively adjusting speed and acceleration to achieve smooth and efficient motion. Below are the main roles and principles of Look-Ahead:
¶ Main Roles
Increase Printing Speed:
- Look-Ahead technology allows for faster speed adjustments without compromising print quality by analyzing the path in advance, thus increasing overall printing speed.
Improve Print Quality:
- By ensuring smooth transitions and preemptively decelerating, Look-Ahead can reduce surface defects such as vibrations and ripples, thereby enhancing the surface quality and accuracy of the final print.
Reduce Vibrations and Shaking:
- When the print path changes abruptly, Look-Ahead can preemptively decelerate to minimize mechanical vibrations caused by sudden accelerations or decelerations, thereby improving printer stability.
Increase Path Accuracy:
- For complex paths, Look-Ahead can plan in advance, allowing the printer to move more smoothly at turns or changes, ensuring geometric accuracy of the print.
¶ Principles
Path Segment Analysis:
- During the actual printing process, the Look-Ahead algorithm analyzes multiple path segments in advance, not just the current segment. This pre-analysis helps the system understand upcoming path changes and make appropriate speed and acceleration adjustments.
Smooth Transitions:
- Based on the information from Look-Ahead path segments, the system can preemptively decelerate or accelerate to ensure smooth transitions at path changes (such as corners or curves), reducing impact and vibrations.
Dynamic Speed and Acceleration Adjustment:
- By dynamically adjusting speed and acceleration, Look-Ahead technology can strike a balance between complex paths and high speeds, achieving both efficient and high-quality printing.
¶ Acceleration/Jerk Control
¶ Acceleration Control Function
Increase Printing Speed: Quickly reach target speed: Acceleration control determines the time it takes for the printer to go from a stationary or low-speed state to the target printing speed. Higher acceleration settings can enable the printer to reach the target speed faster, thus increasing overall printing speed.
Reduce Printing Time: Optimize path transitions: In complex or curved printing paths, appropriate acceleration control can reduce path transition time, thereby decreasing overall printing time.
Improve Print Quality: Reduce vibrations and jolts: Suitable acceleration settings can minimize vibrations caused by sudden accelerations or decelerations during printing, thereby enhancing the surface quality and precision of the printed parts.
Protect Mechanical Components: Reduce wear: More gradual acceleration settings can lessen the impact on mechanical components and reduce wear, extending the printer's lifespan.
¶ Jerk Control Function
Reduce Printing Defects: Minimize surface imperfections: Jerk control affects the instantaneous speed changes when the printer changes direction. Appropriate jerk speed settings can reduce printing defects caused by sudden direction changes, such as bumps or indentations at corners.
Improve Printing Accuracy: Smooth motion transitions: By controlling jerk speed, the printer can achieve smoother transitions during path changes, thereby enhancing the geometric accuracy and detail of printed parts.
Lower Noise Levels: Reduce mechanical vibrations: Lower jerk speed settings can lessen the mechanical vibrations and noise generated during the printer's movements, improving the stability and quietness of the printing process.
Protect Mechanical Components: Reduce impact forces: Appropriate jerk speed settings can decrease the impact forces during path transitions, reducing wear on mechanical components and extending the device's lifespan.
