Arduino Compliing，用于 Ramps 的 Marlin 固件的多重定义错误
Arduino Compliing, Multiple definitions error with Marlin firmware for Ramps
我要组装我的 3D 打印机。因为我不是一个真正优秀的程序员，所以我想使用 Marlin 固件。我只是下载，执行自述文件中的所有操作。
首先，我遇到了一些关于 Libraries 文件夹的错误，但在重新安装程序后就解决了。但是现在我得到了一个很长的错误文本，我根本无法理解，所以这就是为什么，我在这里。我的一个朋友说这是链接器错误，但他不了解Arduino软件。
这是错误本身，我缩短了字符限制，但我希望这足够了：

我认为您的错误与 here 中提到的错误相同，因此尝试按照他说的去做，具体来说：
delete the folder C:\Users\Sastas\Desktop\Arduino\libraries\Marlin
我认为这是因为您将 marlin 放在库文件夹中并从那里启动它。将其移动到草图文件夹，它应该可以工作。
我要组装我的 3D 打印机。因为我不是一个真正优秀的程序员，所以我想使用 Marlin 固件。我只是下载，执行自述文件中的所有操作。 首先，我遇到了一些关于 Libraries 文件夹的错误，但在重新安装程序后就解决了。但是现在我得到了一个很长的错误文本，我根本无法理解，所以这就是为什么，我在这里。我的一个朋友说这是链接器错误，但他不了解Arduino软件。 这是错误本身，我缩短了字符限制，但我希望这足够了：

我认为您的错误与 here 中提到的错误相同，因此尝试按照他说的去做，具体来说：
delete the folder C:\Users\Sastas\Desktop\Arduino\libraries\Marlin
我认为这是因为您将 marlin 放在库文件夹中并从那里启动它。将其移动到草图文件夹，它应该可以工作。
