Prompt Title: XY滑台驅動修正

我想要使用以下程式來驅動我的XY滑台： import serial import time class StageCommander: def __init__(self, port='COM3', baudrate=38400): self.ser = serial.Serial(port, baudrate) self.ser.timeout = 1 # Set a timeout for reading def send_command(self, command): self.ser.write(command.encode()) time.sleep(0.5) # Add a delay to ensure the command is processed return self.ser.readline().decode().strip() # Read the response from the device def drive_to_absolute_position(self, axis, position): command = f"{axis}:GOABSOLUTE {position}" # 注意這裡的空格 response = self.send_command(command) print(response) # Print the device's response def close(self): self.ser.close() # 使用範例: commander = StageCommander('COM3', 38400) # Drive X-axis to position 10: commander.drive_to_absolute_position(axis='X', position=10) # Drive Y-axis to position 10: commander.drive_to_absolute_position(axis='Y', position=10) # Drive X-axis to position 50: commander.drive_to_absolute_position(axis='X', position=50) # Drive Y-axis to position 20: commander.drive_to_absolute_position(axis='Y', position=20) # 結束通信 commander.close() 但發生了錯誤： E21 E21 E21 E21 根據說明書的意思，E21代表的未發送的分隔符錯誤，無分隔符 (CR) 或不正確。 請修正程式碼。
