What triggers the tool change LED (OEM 806).  I expected an M6 to trigger that LED, but it's not.  Do I need to do something in the M6 macro to trigger that LED?  This is what I have for my manual tool change code, which works great.

N8990 G53 Z0
N9000 G43 T2 H2 M6
N9010 M01
N9020 (INSERT TOOL #2)
N9030 (0.125 INCHES DIA. SLOT DRILL)

I'd just like to light the tool change led when the M6 is called.  Is there something I need to add to the M6Start macro?  I suppose I could add a user LED and light it in M6Start and shut it off in M6End, but I'd rather use what's already built in if I can.

Thanks

In General Config, toolchange section, choose "Stop Spindle, Wait for Cycle Start". The LED will be on while Mach3 waits for you to click Cycle Start.

I didn't do that because the first M6 call in the program doesn't require a stop.  I reference the machine with a referencing tool, jog up, insert tool 1 and hit go.  The first M6 call is just to set the current tool and update the DRO's.  I suppose it wouldn't hurt anything to stop at the first M6.  It would just basically require 2 cycle start presses to start the program since the first M6 is only the 2nd or 3rd line.  I could always put the M6 macro code in another macro and call that on the first call instead.

Making a separate macro for the first M6 call worked great.  Thanks for the explanation.
