I know that Gibbs has a good post for most Fagor CNC configurations..... thus, if you haven't gotten the Fagor post from Gibbs, you should contact them. These things are typically just minor problems associated with the correct code format.
If you have additional questions, call Mohit at 905-670-7448.... he is a well informed Fagor Engineeer who can assist you in all questions. Please adhere to what he says, he has been doing this for a long time and will provide you with correct solutions.
Hope this helps and good luck !
