```c
// Define the axis motor step and direction pins
const int stepPin = 2;
const int dirPin = 3;// Define the linear bearing's movement parameters
const float axis_travel = 300.0; // mm
const float step_per_mm = 10.0; // steps per mm
const float max_speed = 100.0; // mm/svoid setup() {
pinMode(stepPin, OUTPUT);
pinMode(dirPin, OUTPUT);
}void loop() {
// Move the axis to a specific position
float target_position = 150.0; // mm
int steps_to_move = (target_position / axis_travel) step_per_mm;
digitalWrite(dirPin, HIGH); // Set direction to positive
for (int i = 0; i < steps_to_move; i++) {
digitalWrite(stepPin, HIGH);
delayMicroseconds(500);
digitalWrite(stepPin, LOW);
delayMicroseconds(500);
}
delay(1000); // Wait for 1 second
digitalWrite(dirPin, LOW); // Set direction to negative
for (int i = 0; i < steps_to_move; i++) {
digitalWrite(stepPin, HIGH);
delayMicroseconds(500);
digitalWrite(stepPin, LOW);
delayMicroseconds(500);

This code example demonstrates how to control the linear motion of the CNC machine axis using the Linear Bearing LMK12LUU. The code uses the Arduino platform and defines the motor step and direction pins, as well as the linear bearing's movement parameters. The `loop()` function moves the axis to a specific position by sending step signals to the motor driver.### Example 2: Using the Linear Bearing in a Robot ArmIn this example, we'll demonstrate how to use the Linear Bearing LMK12LUU in a robot arm to achieve smooth and precise movement.Python Code (using PySerial and Inverse Kinematics library)
```python
import serial
import math
from inverse_kinematics import IK# Define the serial port and baudrate
ser = serial.Serial('COM3', 9600)# Define the robot arm's kinematic parameters
l1 = 150.0 # mm, length of link 1
l2 = 200.0 # mm, length of link 2# Define the linear bearing's movement parameters
axis_travel = 300.0 # mm
step_per_mm = 10.0 # steps per mm# Define the target position
target_x = 100.0 # mm
target_y = 150.0 # mm# Calculate the joint angles using inverse kinematics
ik = IK(l1, l2)
theta1, theta2 = ik.calculate_angles(target_x, target_y)# Convert joint angles to motor steps
steps_theta1 = int(theta1 step_per_mm)
steps_theta2 = int(theta2 step_per_mm)# Send motor commands to move the robot arm
ser.write(b'm1,' + str(steps_theta1).encode() + b'
')
ser.write(b'm2,' + str(steps_theta2).encode() + b'
')# Wait for the robot arm to move
ser.readline()# Send a command to stop the motors
ser.write(b'stop
')
```
This code example demonstrates how to use the Linear Bearing LMK12LUU in a robot arm to achieve smooth and precise movement. The code uses Python and the PySerial library to communicate with the robot arm's motor controllers. The code defines the robot arm's kinematic parameters, calculates the joint angles using inverse kinematics, and converts the joint angles to motor steps. The code then sends motor commands to move the robot arm to the target position.
