请回答以下问题。

您使用的是什么版本的固件?

大师和旧版本进行比较

问题是否可重复?

是的

什么情况下会出现bug?

我的铣床正在运行 VER:1.1F20200319,我在主轴上安装了一个运动学 3 轴测头。我探出虎钳固定钳口,看到以下结果:

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

我的台架测试设置是在 Y 轴上运行 TMC2209 步进器,带有一个小的 0.9 度 nema 17 步进器。运动由 MGN12 直线导轨和 5 毫米导程滚珠丝杠约束。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

在此设置中,百分表移动了 +/- 0.03 毫米,结果为:

奇怪的是,每次测试运行的读数似乎都在增加约 0.003。百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:

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

 

最新大师:

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,步进功能可能会比您预期的多一点(例如一步)。
但是,我们现在不知道为什么每次的值都不一样。
虽然 I2S 静态模式与流模式相比几乎没有延迟,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电机位置在行进方向上的位置比实际位置稍远。

我从未使用过探测功能。
我要去看看这个周末在探测发生了什么。
我将研究它以获得更准确的步进动作。

我注意到了一些事情。
在 I2S 静态模式下,我不会从 st_reset() 或 mc_reset() 执行 I2S 重置。
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 信号后出现误踩踏现象,可能会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读数与该系列中的第一次测试相同。该指标为每刻度 0.002。
