什么停止？

电机卡在第一个点并且不会移动，直到我开始切割另一个形状。

我曾经遇到过这样的情况，弧的范围刚刚超过软限制，导致难以诊断的停止。就我而言，弧线表现良好，但我的工作距离桌子末端有点太近了。
一些 CAM 软件可以生成非常短的弧线，这些弧线在控制器软件的数值精度下表现不佳。在这种情况下，计算的弧有时会非常大而不是非常小，从而触发软限制。
您的问题很可能有所不同，但这是需要检查的。

所有硬件和软件限制都已关闭。加速度为 900 m/sec^2，最大行程为 50000。我尝试从 100 到 10000 的加速度从 1000 到 100000。形状在工作区域的中间，我没有限制问题，也没有返回时出错。

我已经尝试使用从 IO 板上分离的默认代码和默认 grbl 配置，但问题仍然存在。对于切割曲线，在第一点停止仅 1 秒激光信号输出。

我监控了从 PC 到 ESP32 的 G 代码，结果是：

1. 带 LaserGRBL 的 300mm 圆（已加工）
   G90 M5 G0X300.09Y150.09 M4S255 G3X300.09Y150.09I-150J0F2000 M5

2. 带 LightBurn 的矩形（工作）
   G00 G17 G40 G21 G54 G90 M4 M8 G0X62Y82 G1Y345S200F6000 G1X482 G1Y82 G1X62 M9 G1S0 M5 G90 G0 X0 Y0 M2

3. LightBurn 300m 圈（没用）
   G00 G17 G40 G21 G54 G90 M4 M8 G0X57.39Y31.99 G1X54.59Y34.25S200F6000 G1X51.84Y36.58 G1X49.14Y38.97 G1X46.51Y41.42 G1X43.93Y43.93

我周末不在，无法考试。为了帮助调试，您可以尝试不使用激光模式。

我在没有激光模式的情况下进行了测试（$32=0）。问题没有解决，还是不行。

在案例 3 中我没有看到一个圆圈，只有 G0 和 G1 命令。没有 G2 或 G3。

案例 3 是画圆的开始，此后 ESP 停止工作，就像什么都没发生一样。LightBurn 生成的完整 G 代码是这样的：

G2 和 g3 转换为 g1

因此，就 Grbl_Esp32 而言，它根本不会停在曲线上。

有没有换行符？正如给定的那样，我看到一些很长的行会溢出输入缓冲区。也许换行是隐含的，但如果是这样，最好明确显示这些行，以避免任何可能的混淆或误解。

当然它有换行符，考虑 (0x0A) 而不是任何空格。
我以前对带有 lightburn 的原生 grbl (UNO) 没有任何问题。

所以最后一个有效的动作是
G1X43.93Y43.93
然后它停止了，在执行
G1X41.42Y46.51？

或者它是否在序列内的其他地方停止

G00
G17
G40
G21
G54
G90
M4
M8
G0X57.39Y31.99
G1X54.59Y34.25S200F6000
G1X51.84Y36.58
G1X49.14Y38.97
G1X46.51Y41.42
G1X43.93Y43.93

当 lightburn 运行时，我使用串行分析器进行监控，我捕捉到的最后一行是 G1X43.93Y43.93 并且过程从未继续。

你用过lightburn的控制台手动输入GCode吗？当我尝试这样做时，我在 $32=0 的 M4 命令之后看到了“错误：20”，但在 $32=1 的情况下一切正常。使用 $32=1，我能够运行包含一个大圆圈的轻烧作业。

我们还需要知道您正在使用哪个 Grbl_Esp32 版本和分支，以及哪个机器文件，以及您对该机器文件或 config.h 或 defaults.h 所做的任何编辑

我使用的是没有 machine.h 文件的旧版本，也没有 SPINDLE_TYPE 选项。
我更新到最新版本并设置SPINDLE_TYPE 为SPINDLE_TYPE_LASER. 现在问题解决了。但是有一些问题USE_RMT_STEPS我会在另一个问题中讨论
