Yes that is true.
Been trying with the macropump and I cant get it to work
as I said I am new to VB so it may still be possible. In the mean time it wouldnt take long to edit your code, even if you have 50 plunge moves all you would need to do is open your code in notepad, press Ctrl + F, type in the plunge move (eg if the plunge is G0Z1, type that in) then hit find next. You can then enter a new line below such as M1 then press find next and so on, should only take a minute to do.
Sorry cant be much more help
