关闭 CreativeRobotics 开启了这个问题 2015 年 10 月 8 日 · 7条评论 关闭 GRBL 松动位置#812 CreativeRobotics 开启了这个问题 2015 年 10 月 8 日 · 7条评论 注释 创意机器人 评论了 2015 年 10 月 8 日 我现在有几次 GRBL 会在工作期间更改 Z 偏移量 – 我相信它不仅仅是由于加载或速度而丢失的步骤。 第一次发生时，它在工作开始时失去了几毫米 (+) 的位置，它始终如一地这样做，我看不出 G 代码有任何问题。这是一个凹槽操作，尽管在工件顶部进行了归零，但当它到达第一个凹槽位置时，它总是会结束大约 +2 毫米。每次我都会重置位置并以不同的进给率再试一次，它总是发生。第二次在雕刻作业中移动了 0.4 毫米。我保存了该文件并标记了 Z 偏移发生变化的点。每次我运行该作业时它都会始终如一地执行此操作，甚至在更改进给率之后也是如此。 我的机器是shapeOKO，GRBL build 0.9i.20150329 机器设置是： $0=10 (step pulse, usec) $1=255 (step idle delay, msec) $2=0 (step port invert mask:00000000) $3=0 (dir

我现在有几次 GRBL 会在工作期间更改 Z 偏移量 – 我相信它不仅仅是由于加载或速度而丢失的步骤。
第一次发生时，它在工作开始时失去了几毫米 (+) 的位置，它始终如一地这样做，我看不出 G 代码有任何问题。这是一个凹槽操作，尽管在工件顶部进行了归零，但当它到达第一个凹槽位置时，它总是会结束大约 +2 毫米。每次我都会重置位置并以不同的进给率再试一次，它总是发生。第二次在雕刻作业中移动了 0.4 毫米。我保存了该文件并标记了 Z 偏移发生变化的点。每次我运行该作业时它都会始终如一地执行此操作，甚至在更改进给率之后也是如此。
