Thanks Tweakie,
Good point, editing existing code looks pretty easy for these laser commands.
FYI
if you have not downloaded it yet, Notepad++, really works well for modifying code.
BTW
I Added air assist on my 150 W laser and WOW what a difference it makes.
initially I only had a slight airflow to keep the lens clean, I upped it to 60 PSI.
Thanks again for your help,
Chuck
