The unique, magnet-driven cutter design replaces traditional springs, extending the cutter’s lifespan, while the extruder cover offers a transparent view of the gears. An integrated waste material chute and silicone nozzle wiper keep everything clean and precise.
Quiet Operation
Designed with five servo motors and optimized FOC algorithms, the K2 Plus keeps noise levels at a modest 48dB on average (45dB at standard speed for monochrome printing), so it’s easy to integrate into any workspace.
What is FOC?
Field Oriented Control (FOC) is an advanced technology used to control electric motors, especially brushless DC motors and stepper motors. Here’s a simple breakdown of how it works and its benefits:
- Real-Time Position Feedback: FOC constantly monitors the motor’s position. This means it can quickly adjust how it controls the motor to keep it running smoothly and accurately.
- Fast Response: This system can react quickly to changes in load or commands. That makes it great for applications where precision and speed are important.
- High-Frequency PWM: FOC uses a technique called high-frequency Pulse Width Modulation (PWM) to manage the current flowing to the motor. This helps to make the motor run more smoothly, reduces noise, and improves efficiency.
- Matching Torque with Energy: FOC ensures that the motor gets just the right amount of energy it needs to produce the required torque. This helps the motor run efficiently while keeping the overall load relatively low.
In summary, FOC technology enhances the performance of electric motors by making them more responsive, efficient, and precise. It is widely used in various fields, including industrial automation, robotics, and self-driving vehicles..
