我正在尝试使用高度图图像，但似乎插件中止并显示如下消息。我也附上了设置的图像和屏幕截图。

用锥形钻头测试：

创造1c

我最初没有使用 3.8.2，但现在验证了行为相似（见下文）。此外，bCNC 的版本是 0.9.14，这是由py -m pip install bCNC

从错误来看，似乎立铣刀设置可能有问题？我尝试使用屏幕截图中的确切设置，但无济于事。

我假设它使用从立铣刀菜单中选择的任何工具是否正确？
我的工作流程是：
点击“End mill”-> Setup endmill values
打开菜单 CAM，子菜单 Generators，Heightmap
选择文件
点击“heightmap”执行按钮
工作 1-2 秒，然后显示错误。

此外，我在我的 Windows 机器以及连接到我的工厂的 rPI 上尝试了这个，结果相当。

Traceback (most recent call last): File "E:\Python\3.8.2\lib\site-packages\bCNC\Utils.py", line 526, in __call__ return self.func(*args) File "E:\Python\3.8.2\lib\site-packages\bCNC\ToolsPage.py", line 1747, in exec ute self.tools.getActive().execute(self.app) File "E:\Python\3.8.2\lib\site-packages\bCNC\plugins\heightmap.py", line 326, in execute MAT.pad_w_zeros(TOOL) File "E:\Python\3.8.2\lib\site-packages\bCNC\lib\imageToGcode.py", line 823, i n pad_w_zeros temp[to:to+w, to:to+h] = self.matrix TypeError: slice indices must be integers or None or have an __index__ method

我能够通过将 imagetogcode.py 的第 823 行更改为读取来使插件工作

self.t_offset = int((ts-1)/2)

老实说，这非常令人费解。我之前没有看到高度图插件或其依赖项 imageToGcode 有任何问题，就像我说的那样，它无需修改即可为我工作。我确实知道两者都需要进行一些改进，但之前没有什么能阻止它运行。在我看来，用户似乎有不同的结果，但为什么呢？我在 py2 和 py3 中测试过，它很简单。

创造1c

问题似乎是这条线之前（没有转换为 int）被评估为浮点数。这似乎导致了索引的下游问题。我所做的只是将演员表添加到一个 int 中，现在它可以工作了。

至于为什么会这样，我不确定。在我的调试器中，ts 的值为 3，所以 (3-1)/2=2 应该是一个整数？不是一个巨大的 python 专业人士，所以我也在这里不知所措。

如果您对我如何进一步测试有任何想法，我很乐意接受它，以确保这不会发生在其他任何人身上。

GitHubCaps

@creat1c我很抱歉！刚刚意识到我使用了自己的 image2gode 而不是 imageToGcode。

我有一个不转换为整数的固定版本，而是使用self.t_offset = (ts-1)//2
我将把它放在这里供您尝试。希望很快，我会在这里提交/推送它。

这个修复了 py2 和 py3 的所有弃用问题！

啊! 感谢您检查。
我还有一个问题 – 步长通常取决于铣削钻头吗？它使用非常精细的网格（0.1 毫米）而不是我选择的铣削钻头（1 毫米），我想知道我的修复是否有副作用？
