I just joined the forum.  I'm completely new at Mach3 but not cnc.  After a couple of long nights I can move around Mach3 for most things.  I copied a profile and want to make it the default when opening Mach3.  Something is wrong because when I right click on the Mach3 logo and change the target it doesn't default to my profile.  My target address is something like

C:\Mach3\Mach3.exc /p name

I've tried various combinations and it still doesn't open with my profile "name"

Also does anybody know where I can copy a macro for a two touch probe?

Check your Mach3 folder for "YourProfile.xml" file.
Try MachLoader, if your created profile is present, it should be visible in list of profiles.
