    Fanuc 21i-T improper G-code G13.1

    Hi guys,

    when i write my program with a inter-polar milling operation on my Colchester machine,

    i noticed that the g code 13.1 will cause an error named improper G-Code.

    why is this G-Code improper?????

    what can i do to solve this problem ?

    waiting for your thoughts

    greetings from Germany

    Strange if it allows G12.1 G13.1 should also work, what about G113?

    Hi Max,

    Post the line G97 S1200 M13 before the G12.1 ( or G112 ).

    Change GO C0 to G0 C0.
