请回答以下问题。

您使用的是什么版本的固件？

要比较的主版本和旧版本

问题是否可重复？

是的

什么情况下会出现bug？

我的铣床运行的是 VER:1.1F20200319，我在主轴上安装了一个运动学 3 轴测头。我探测了虎钳固定钳口并看到以下结果：

观察到每刻度为 0.002 毫米的刻度盘测试指示器，并记录了停止位置的变化并与读数相匹配。

我的工作台测试设置是在 Y 轴上运行 TMC2209 步进器和一个小型 0.9 度 nema 17 步进器。运动受到 MGN12 线性导轨和 5mm 导程滚珠丝杠的约束。我的配置、diff vs master 和 i2s 机器设置可以在这里找到： https ://gist.github.com/jschoch/90c695ced0146bb0ccefcd825b24458a

千分表在此设置中移动了 +/- 0.03 毫米，结果为：

奇怪的是，每次测试运行的读数似乎都在上升~0.003。千分表没有显示出这种稳定的增长。

感谢您的报告。
从 3 月 19 日版到现在，Probe 的处理流程似乎没有任何重大变化。

版本：1.1F20200319：

Grbl_Esp32/Grbl_Esp32/运动控制.cpp

第 332 行 d4121b8

uint8_t mc_probe_cycle ( float * target, plan_line_data_t * pl_data, uint8_t parser_flags) {

 

最新大师：

Grbl_Esp32/Grbl_Esp32/运动控制.cpp

第 341 行 35cb11d

uint8_t mc_probe_cycle ( float * target, plan_line_data_t * pl_data, uint8_t parser_flags) {

 

所以我的猜测是，在使用 I2S 进行探测时，步进器功能可能会比您预期的多一点（例如一步）。
但是，我们此时并不知道为什么每次的值都不一样。
虽然与流模式相比，I2S 静态模式几乎没有或没有延迟，但它实际上有 4μs 到 8μs 的延迟。如果探针在这个小延迟期间检测到信号，则可能是探针点感知到的电机位置在行进方向上比实际位置稍远。

我从未使用过探测功能。
这个周末我要去看看 Probing 上发生了什么。
我将研究它以获得更准确的步骤操作。

我注意到了一些事情。
在 I2S 静态模式下，我不从 st_reset() 或 mc_reset() 执行 I2S 复位。
即使在 I2S 静态模式下也执行 I2S 复位的更改可能有助于阻止轻微的意外电机运动。
检测到Probe 信号后立即复位I2S，可以防止检测到Probe 信号后意外步进，并可能稍微改善电机位置超前的现象。

我切换到 devt，这是我的结果。它仍然在不断攀升。我不认为我有机械问题。探头接触时没有间隙，我摆动滚珠丝杠。

这次我似乎走了另一条路。表盘测试指示器的误差范围为 +/- ~0.01，但最后一次测试显示的指示器读数与本系列中的第一次测试相同。该指标是每刻度 0.002。
