Cannot get Mach 3 to run sub progams
« on: July 13, 2008, 11:15:39 AM »
Hope someone can help. I've been trying for days to get Mach3 to run a sub-program, without success. I've searched the forum but found no answer that works. I used to be able to run subs until a few days ago.
Here is an example of a simple sub that Mach3 won't run:

G00 G90 G17
X120 Y0 Z0
M98 P1001 L2
M30

O1001
G01 G91 X-1
G90 Y5
Y0
M99
%

Please could someone tell me what I'm doing wrong... :'(

Oops... :-[
Title of this thread should have been "Cannot get Mach 3 to run sub progam (unless I write the sub program file on a Windows computer)"

I don't use Windows for anything except Mach3. For all other computing I use Red Hat Linux (Fedora). Sooo  I wrote the program file, including the sub, on my usual computer rather than the Windows one in the workshop. Odd thing is that the main part of a program will run but not the sub part  ???

It's only the fact that Mach3 is such a superb piece of software that I allow the abominable Windows OS in my workshop at all. As I have no plan to edit with Windows software, I just need to figure out which hidden characters Linux uses that Mach3 doesn't like. Then I can set my text editor to not insert them. Must be something to do with the: line end - carriage return. I think Windows does something weird at this point that Mach3, as a Windows program, expects to find.

Hi BB,

I suspect it will be a line or file termination issue. DOS Text in Windows has a #13#10 byte pair (Character 13 = Return, Character 10 = Linefeed) and I suspect Linux is probably only using one of those. DOS Text in Windows also uses #26 (Character 26 = EOF = End Of File) and Linux may be using something different.

Best way to check is to use a raw (Hex) file viewer to see what hidden characters there are the end of a line and enf of the file.

There's a free Hex viewer and editor here...

Actually on that website, go to the "other freeware" and there is a free app to convert Linux text files to DOS Text format. It appears Linux uses #10 ( Hex 0A ) as the only end of line marker.

Here is the direct download link for it.

Thanks for the tip Dave.

I have now found that there is a simple Linux command line program that works a treat. It is "unix2dos". Very easy to use, works every time.  :)
This program is part of modern Linux distros and is probably already installed on most Linux computers.
This might help other folk who edit with Linux computers.

Try posting your sub-routine in the "Subroutines" folder. I cannot quite remember how it works, I will have to think about it some more, but if you post the subroutine there, you can then call it from the main program. The only problem is, I can't remember how to call it. I will go have a look on my workshop machine, there are none on this machne.
Not me driving the engine - I'm better looking.

This would be really useful if I knew how to do it. At the moment I have a common set of working parameters and calculated variables that I use in a number of part program files. It would be great if I could store these in a special file and refer to it from all the other files. This should be very easy to do, anyone know how to do it ???
