I need to have the M6 command in MachTurn modified.  I need it to do a G53 G00 Z-0.200, then G4 P3 as part of the tool change.  In the list of Macros i Mach I see M6Start, M6Startnew  and M6End.  Any suggestion on which macro MachTurn uses for the tool change and what the code needs to look like to add my commands?
Thanks.
