David Jupp:
Not all controllers recognise M30.  May or may not be part of your problem.
Will_D:
Thanks for the reply David, the M30 just causes a beep at the end. Same problem without it. I just like the beep to say its run to the end of the file

Will, after my troubles with a second set of parentheses within a comment (see #284), I would be very cautious using any text within the file title that was not straight alpha-numeric......so remove the "_" from the filename.
Sounds really stupid and probably not the solution but worth a try!

Will,

M30 is not only end of program, but also 'rewind', so the code pointer should reset to the top of the list.

(name derived from the old paper tape program loading days that sadly I remember well  :bugeye: )

Latest trip to Frustration Towers i.e. the garage.

Switch On controller and reset it.
Run this little "Safe Program":

(Project Make Safe)
G17 G21 G90 G40 G49 G80

F250.0
G00 Z5.000
G00 X0.0 Y0.0 Z0.0

M30
%

Ok it runs to the end and beeps as expected Displays are 0,0,0

Run this little file (now named MT01.txt)

G00 X0.0 Y0.0
G1 X20.0 F400.0
M30
%

Ok as expected Feed Used 400, X left at 20, Beep

Run this little file (MT02.txt)

G00 X0.0 Y0.0
G1 X20.0 F400.0
G1 X30.0 F300.0
M30
%

and it stops on the line #1: G1 X20.0 F400.0 leaving x,y at 0,0

However if I run the safe program it then works as expected.
