What are the possible causes of a CNC machine displaying a 'soft overtravel limit' error, and how do you resolve it?

A 'soft overtravel limit' error on a CNC machine indicates that a commanded axis movement has exceeded a programmed software limit. These software limits, stored in the machine's parameters, define the permissible travel range for each axis. Several factors can trigger this error. First, programming errors can cause it. An incorrect coordinate in the CNC program can command the axis to move beyond its limit. Second, incorrect work offsets can cause it. An improperly set work offset can shift the coordinate system, causing the programmed movements to exceed the soft limits. Third, machine setup errors can cause it. If the workpiece or fixture is positioned incorrect....
