To more experienced users this may not be a big deal. For me, it really makes life a lot easier.
I can turn on my Spindle on with a "M03" command and turn it off with "M05". I can also pause with a "G04 PXXXX" command (ex "G04 P3000 pauses my system for 3 seconds - this allows the spindle to get up to speed before cutting anything).
Today, I asked Vectric if they would consider implementing an option to include these commands in a header and footer of their g-code files in future versions of their product. They told me to edit my post processor!
All I had to do was add the commands
to the header section in my post processor file
to the footer section for these commands to automatically appear in the g-code output.
Before I had to add the commands manually. This is better!
