What does the error M7066 mean?

Is the slide table touching the limit?

Has the distance between the slide table and the X6 end of the origin changed lately?

Is the X6 endpoint of the origin being used correctly in the machine code for the KM-ASS
The M7066 error denotes that the left limit of the X axis is abnormal and far away from the origin end (X6). Checking whether the slide table touches the limit is recommended to solve this issue.
