Invalid Machining Start Point

What does 3505 mean?

This MC alarm (specific to Series 30i) indicates that the machining start point defined in the program is invalid. This could be due to a coordinate outside the work envelope, an unreachable point, or a point that interferes with existing geometry, preventing the machining cycle from initiating correctly.

• The computed start point for the cutting path is not achievable.
• Previous operation left the tool in an inaccessible position.
• Axis home position has been lost or incorrectly set.
• Program error in defining the first move of a contour.

1. 1

   Modify the machining program to specify a valid and reachable machining start point.

2. 2

   Alternatively, modify the machining program to enable automatic determination of the start point by the control system.
