GRBL 命令/评论问题 #1103

同步人

我为 OctoPrint 维护了一个插件，可将 GRBL 扩展到该平台 ( https://github.com/synman/Octoprint-Bettergrblsupport )。

在评论方面，我注意到激光/CNC 切片机存在相当多的差异。

我猜 GRBL 对通过记录的 gcode 传入的 % 字符感到窒息。它回应Recv: error: Expected command letter

我有现有的逻辑来去除以“（”和“;”开头的行。我想知道是否也应该去除％。我目前不知道为什么它会包含在（提供的）gcode中。也许是一个切片器正在使用它作为标记 gcode 的“开始”和“结束”的分隔符。
