Hello all,

[crazycnc]

We have just set up our first CNC machining centre, so I'm pretty new to all this. It's a Bridgeport 412X Interact with Fanuc O-Mate M control. (1991 machine). We got it used and the manuals don't seem to be the greatest. I have made a program that uses the tool changer, and that seems to work all right, but I can't figure out how to change tools in MDI mode.
The manual says to enter G30 G91 Z0 T(number) M06 in MDI mode. I do that and the Z axis moves to the tool change position, (the "Z-axis at tool change position" light comes on, so it must be at the right position), but now it just sits there and doesn't do anything more. Any ideas? Maybe a modal G-code not set right?

Note that I use exactly the same code in my program that does work

Thanks for your help,
Lorne

Try to put M6 on a seperate line after "G30 G91 Z0 T(number)"

G30 G91 Z0 T(number) ;
M6;

[crazycnc]

thanks for the quick reply. I tried that, but still no go. Any more ideas?

[Mitsui Seiki]

Try this:

G30G91Z0;
T#;
M19;
M6;

[crazycnc]

OK, we're getting closer. The M19 is orienting the spindle, but still no tool change

[Mitsui Seiki]

Yes, but you should find M19 in the M6 macro.
Strange.M6 works inside a program but not in MDI?

Ok,try to do this:
G80G40G49
G30G91Z0
T#
M19
M6

Use M16 instead of M6. Be sure z-axis is at zero

We finally had a tech out. He couldn't figure it out either, but it turns out there's a small program you have to run in auto mode to rotate the turret, seems kinda wierd, but I guess it works.
