GPIO.setmode(GPIO.BCM)
DIR_PIN = 17
STEP_PIN = 18# Linear motion settings
STEPS_PER_MM = 10
SPEED_MM_S = 5# Initialize GPIO pins
GPIO.setup(DIR_PIN, GPIO.OUT)
GPIO.setup(STEP_PIN, GPIO.OUT)def move_linear(distance_mm):
# Calculate number of steps
steps = int(distance_mm STEPS_PER_MM)
# Move linearly
GPIO.output(DIR_PIN, GPIO.HIGH if distance_mm > 0 else GPIO.LOW)
for i in range(abs(steps)):
GPIO.output(STEP_PIN, GPIO.HIGH)
time.sleep(0.001)
GPIO.output(STEP_PIN, GPIO.LOW)
