I have read many forums and PDFs on this subject but still cannot seem to have complete success. We are able to send and receive programs, but our problem is that the Mazak sends in EIA (G-code) and when we send it back the Mazak puts an E at the end of the program file instead of an M so the control doesn't read it. Please tell me what I am missing! I feel we are so close, gotta be something simple. Thank you in advance for your time on this.
