Generaly,
Modify the button script so that it codes G95 instead of G94.
Operator>Edit Button Script, select Post Code button, look thru the script and change accordingly
You can have wizards, done by different people, which do the same task and but the scripting varies ie; some default to your configuration, so provide choice of feed mode, some don't, some don't allow modification of the script.........so need to look at the scripting.
