i know setting 15 will lock the tool to match the height
is there a way to make sure the dia matches as well?

hypothetical example;
wrote a program, set all the tools, then manually changed from T5 to T25 due to problem with tool holder
ran program and it errors because of mismatch T & H
manually change to H25
ran program, crunch due to wrong dia in offset page
forgot to check for D5

so can they be locked all together?

didnt happen (yet!) but we came close
but just thinking out loud

I do not think there is any way to tie Tn, Hn, and Dn all to the same number like Setting 15 ties T and H together.

I have done your 'crunch' in reality several times over many years and hundreds of programs. But even if I could tie T and D to the same number I probably would not because often I use two, or more, tool diameters for the same tool.

Two ways you could do it if you have macro programming capability: -

1. Setup a macro program that is called up on your G43 Hn; command,
which contains something along the lines of .....

%
O9???;
G43 H#11;
D#11;
M99;
%

2. Something similar to my approach which is to program Tool numbers as variables stored in a sub program eg ...

T#101 M6
G43 H#101 D#101

That way if the tool number changes you only have to change a single number in your sub pgm :

#101=1 (Face Mill)
#102=6 (End Mill)
#103=5 (Drill)

On Haas it would be best to make this sub part of your main program (and you would need to make sure it was called at every restart)

Instead of using the actual 'D' number, enter 'D#4120'.
This will use the 'D' value for the last called tool.

Fine in all instances other than if you are running a side-mount t/c and are doing a preload of the carousel, i.e.
T1 M06;
T12;
With this command, T12 is the last tool, so the control would use the D12 value not the D1.
