Questions about Fanuc 3M

[AccuMillGuy]

Hello. I have a YUASA AccuMill AM-1547 with Fanuc 3M controls.

I am looking for a full list of programming codes that apply to the 3M system. I have BobCAD V22 and I’ve already noticed that BobCAD uses I & J, I can not edit I & J lines on the 3M keypad.

Does anyone know what information I need in order for BobCAD to communicate to the mill properly? I have RS232 connection.

Thanks

Even that I,J&K are missing from the keyboard, 3M will execute properly G2/3 with I,J&K center. As an alternative, you can set Bobcad's postprocessor to generate G2/3 with R.
In the earlier, even DOS versions there was a communication program in the package. Set it to Even parity, 7 data bits, and depend on parmeter setting 1 or 2 stop bits, 4800 baud rate.

P.S. 3M-A controls made under licence in Bulgaria had 2 patches for IJK, one was holding down PRGRM, X became I, Y-J, Z-K. Another one was to push the button 3-4 times and it changed X, 4, I, 4. Just for curiosity, I do not think someone can find such a version outside Bulgaria or neighbouring countries

Thanks for your help. I've got the mill communicating to my PC flawlesly using your settings! Thank You

But...

Now I have these issues...


PS: I am using BobCAD V22 to create the program and I use Predator V7 to upload the file to my Mill.

#1 - After uploading the program to the Fanuc 3M control, the user comments inside the brackets ‘( )’ disappear completely. They are there in BobCAD and they are there in Predator, I have double and triple checked all options related to comments to make sure they are not ignored or omitted... I still get no user comments...

#2 - The M03 and M04 commands in the programs uploaded to the Mill do not work. I can go into MDI mode and start n stop the spindle, I can also write a simple program at the controler and the spindle codes will work. But when I upload a file from my computer the M03 and M04 codes no longer work, they are ignored...

Any ideas???

Thank You

Adam,
The brackets will not be seen in the control, 3M/3T strips them out in order to save memory. Remember, this control was designed around 1980, when CMOS memory was quite expensive.
About M3/M4, first try to put S-code on the same line (M3 S200),
second, check the door interlock.
The spindle may be enabled in MDI with door open, but not in auto mode.
Best regards.

Hello AccuMillGuy,
I have a machine with a Fanuc 3M also. F-bu is correct, I can't input comments either.

On #2, this may be a long shot but is your post outputting an O or zero?
