Right down to the order of T#M6 or M6T# and are you using the 9001-9009 macros or the 9020-9029 macros. There are many ways that this can be set up and it will all depend on how you have your tool call set up. So if you do a T3M6 then #4021 will equal 3.

Example is if your variable for tracking the current tool is #1031 your tool change program should look something like this. Then all you need to do is run a check line in your tool change macro to bypass the M6 if needed. Not all MTB did this so if you have to you can set up a common variable one of #500-#999 to track to tool in the spindle. Yours I am sure will be different refer to your MTB manual. There is probably a system variable set up by the MTB to track the current tool in the spindle. I do this when writing all of my tool change macros. If not then your other solution is to bypass the M6 in your tool change macro if the current tool is in the spindle. If it is written into your ladder to instantly alarm out when it sees the T value of the same tool in the spindle with a M6 command then you are screwed.

It is the most idiotic bonehead idea I have ever seen. I had the same problem with a 5 axis that I just set up for production. Yes some MTB wrote into their ladder logic to alarm out when calling the same tool in the spindle. That’s not to say that there is not one on the 10m. I have never come across this type of parameter on any of the Fanuc’s that I have set up. If you have a parameter for this as Moaprecision has said then that is the best route to go.
