Any fanuc experts out there?

I havn't seen one that can't. unless it needs T0303M06

Nor I.

If I understand the OP's question correctly this will execute as a single block in MDI:

T5 input M6 input cycle start

M codes are written by the MTB, not Fanuc. I've seen this work both ways on milling machines and sometimes for good reason.

You will have to change the PLC.

T5 input M6 input cycle start\

That's what I am trying to achieve.

The macro runs when M6 is ran. I wish it was when the T is ran, I could just add an M6 to it. But I'm afraid your right, can't be done as the software is currently written.

What flavor (model) Fanuc?

uy on the planet knows fanuc...but...

Yup...this is a MTB issue, not Fanuc. I have seen this before on a Mori....would error out whenever you tried it on the same line. Never could get a straight answer as to why....

guy on the planet knows fanuc...but...

Tool needs to be staged in carosel / turret prior to executing M6, ran a Mori that had that "feature", same as Zym. Thus, as said earlier: T6 enter m6 enter cycle start

Vinny, My Fanuc Oi control runs like that.

c guy on the planet knows fanuc...but...

Now that I think of it...the Mori was even more confusing. Lets say your first toolchange went like this...

T1 (eob) M6 (eob)

would bring up tool 1

now to mess with your head.....

T1 (eob) M6 T2 (eob)

would bring up tool 1 and stage tool 2...and the next toolchange would look like this....

M6 T3 (eob)

That would change to tool 2 and stage tool 3. Once you got used to it it was not bad....I always used to make redundant callouts just to keep things straight.

(eob) =3D End Of Block

Vinny, The control has the M6 written as a macro. Very common, and useful.

Just enter: M6T5 input Cycle Start

if it doesn't see the M6 first in the line, it gets "confused"

Just enter whatever preparation commands that to be done as a short subprogram in your main memory and then don't mistakenly delete the sub.

The subprogram which follows is for one of my machines which is a 4 axis horizontal machining center having 8 pallet pool and a separate floor mounted 80 tool hive all interfaced to a 6m fanuc controller ( a configuration in which there is a for all 3 axis to pre-positioned to second ref point via issuance of G30 prior to executing any actual M6 code and so there is proximity verification switches built into the plc ladder)--(and so it follows the the program below would need to be altered on as-needed basis in order to suit any specific machine because for instance with your typical vertical there is no need to position the x and y axis all and also the physical toolchanger arm position most likely corresponds to the home position G91G28Z0) :

% :9000 M05 M09 (BPC TOOL CHG. SUB PROG. 9000) G0 G91 M19 G30X0Y0Z0 M06 G0X-4.Y-4. G90 M99 %

Once your sub resides in main memory, all you will then need to do for single line tool change in MDI mode is to execute the sub by entering the following block of code and then press your cycle start:

T14M98P9000

It might. I've seen machines where the order mattered.

Like this idea if the other suggestions don't work.

Write a tool change macro and tie it to a custom G code so Vinny only has to input something like G??T3 (to execute tool change macro and call up tool #3).

So Vinny what Fanuc you got? Macro B enabled?

Try and down load the 9000 series programs. Your tool change macro will be one of them if it's done as a macro. Screw with it at your peril.....
