启动文件流时出错：null #223

我一直在尝试每晚使用 1.0.7 到 1.0.8 版本（截至 2015 年 2 月 7 日）。在所有这些版本中，但不是在 1.0.6 中，当我试图将工作发送到我的 Shapeoko 2 时，我经常收到错误提示“启动文件流时出错：空”。除了“频繁地”。发生此错误后，我有时可以重置我的工作并重试，问题不会发生。

这个问题通常很早就出现了，通常在发送的 gcode 不到 100 行之内。但是，我记得看到它在很久以后至少发生过一次。在某些情况下，机器将继续正常运行。在其他情况下，它会完全停止。

这是错误和 UI 的屏幕截图：

启动文件流时出错：null #223

这是带有堆栈跟踪的控制台输出：
