Problems with CNC Mill using Fanuc 0 Mate Controller

Hi experts

Recently I got a CNC Mill that was built in 1986. It uses a Fanuc 0 Mate Controller. This is my initial experience with CNC, and I'm facing some problems.

By using Mastercam 9, I built a simple program, got that seemingly fine in MC, classified the tools, etc., that were verified fine, and applied the Post Processor MPFAN.pst and generated the NC file.

Moreover I use the baud rate set OK in MC9 and prepared a serial port cable. By using the serial port when I started downloading a program from my PC to the Mill, I found an Error Code 071.

First I set the mode switch to "Edit" and then pushed the "Program" button and then the "Input" button to load the file. The screen was winking "LSK" at the lower right corner.

That's what my files showed to be right. Then I opened Mastercam's interface program, chose the COM port and Baud Rate, etc, chose the file to load "test2.nc." The output screen on the PC ended with the first few lines of the NC file showed, and the Fanuc controller displays error 071.

I read some tips for this error code on the forum, so I tried including a % as the first line but it didn't work. Moreover the person I bought the Mill form suggested that I enter a Program Name on the panel. So first I pressed Program, and then O0100, then Input, then downloaded the program but still found Error 071.

Now I'm trying to send the first few lines of the original file:

N0M5

N0G91G28Z0.

N0G28X0.Y0.A0.

N0M01

N0T1M6

N0G0G90G53X-6.455Y3. A0.S5000M3

N0G43H1Z1.

N0Z.1

N0G1Z-.25F6.42

N0Y1.F20.

N0G3X-5.Y-.455R1.455

Please give me a solution. Need your help.

Thanks a lot.
