I am not sure, its unlikely but you never know. Having said that if it works fine in an older version then I dont think the screenset is the issue.

The screenset should really have no effect on the way Mach3 runs at all, except when the macros that are supplied with it are running. The 2010 Screenset does Run From Here exactly the same as the standard screenset, with a button calling the system function "Set Next Line".

Gerry,

Thanks for your comments also.  Where is the Set Next Line function call located?  If you know.

Thank you.

It's an internal function that you assign in the Screen editor. It's the "Run from Here" command, but it's called "Set Next Line in the screen designer.

How do you access it?  I would like to compare what is in 66 and in my older version.

Thanks

Open the screenset(s) in Screen4 and check what the button is assigned to do. either right click or double click the button to bring up it's properties.

Gerry,

Ok, that gives me the properties but I want to look at the code.  How do I find that?

Thanks

There is no code, it's a built in function that can't be modified.
