我该如何纠正这个错误？

似乎是 gcode 有问题，而不是查看器。
为了测试，我将它减少到第一条 G17 G3 线，我得到以下图 G17 G3 要求在 XY 平面上从 X-31.712 Y201.6 Z-4.5 开始到 X-32.312 Y201 I-31.712的 CCW 圆J201 因此中心应该在左上角的 X-31.712-31.712 和 Y201.6+201 wrt 到起始位置，因此它需要逆时针旋转一个几乎 358 度的圆。 如果 I31.712 J-201 为负数，则错误出现在 I,J 上，然后它会正确显示为圆心，圆心位于起点右下角。

我也在其他在线查看器https://ncviewer.com/上测试过它 ，我得到的情节与 bCNC 中的情节完全相同。

我又试了一次，现在我得到了预期的结果。在编译代码时，我可能错过了其中一个步骤。非常感谢您的及时回复，您救了我的命！

这似乎是 cam 程序中的一个错误，很高兴重现并向他们报告。
