I have a program that produces G code from drawings ("Promotion Nest").
The programs sets at the begining of the program M28 and at the end M29.
So, i created two new macros (in the macros folder) M28 and M29.M1S .
M28 contains only that: ActivateSignal(output1)
and M29 contains: DeActivateSignal(output1)
Now when i open a file (any file), the toolpath screen does not show the drawing, and sometimes if i try to move by right clicking, goes back to the first screen.
If i delete these two files, the screen shows the drawings as well.
Do you have any idea of what is going on?

Are your macros in the profile you are using?

or you can try this.

in your macro type :-

If not IsLoading() then
  activatesignal(output1)
end if

Yes the macros are in the profile that i'm using.

Graham, the first line produces compilation error:

If not Isloading() Then
.
.
.
Endif

Why is that?

OK, try it this way

If IsLoading() then
else
activatesignal(output1)
end if

Graham.

Graham, still has compilation error.
Why is it so difficult for the program to do it?
Its a simple code.

They work here, here are the 2 macros :-

Try them and let me know.
