G-Code Combination Invalid

What does 3512 mean?

This MC alarm (specific to Series 30i) indicates that G codes specified in the program cannot be combined as programmed. Specifically, a figure block has been paired with a machining type block that is not compatible or available for that figure type, leading to an invalid operation sequence.

1. 1

   Modify the machining program to specify a correct and compatible combination of machining type block and figure block.
