Mac系统下3018 Pro激光雕刻G代码执行报错求助

连续三天排查仍未解决，Mac系统操控3018 Pro CNC机床进行激光雕刻时，出现以下报错：

1. 初始报错：
   Error 20 - Unsupported or invalid-code command found in block. [M106 P0 S255]

2. 移除M106 P0 S255代码行后，新报错：
   ALARM: - Reset while in motion. Grbl cannot guarantee position. Lost steps are likely, Re-homing Aladeen highly recommended. [undefined]

已尝试的排查措施 #

• 安装CH340驱动，无效果
• 更换不同软件生成G-code，仍出现相同错误
