Re: How to make Mach3 go line by line in the g-code?
You can manually enter M0 codes, and setup Mach 3 to stop on an M0 until start is pressed.
Simply duplicate the code and insert the M0 in the appropriate different places on each duplication.
An alternative might be to insert a G4 P(x) at every point you might want to stop and take a picture. Set (x) to whatever length of time you need. When it pauses you can either take a picture or not.
If you want to magically have Mach 3 read your mind and automatically stop at differing random points along the way, you don't have enough computing power for that kind of Artificial Intelligence.
