A simple change???

[Triode]

Hi, I am looking for a simple way to change G-code so that on every instance of a rapid (G0) there is an M31 before, and an M32 aft.
For Example

This:-
G1 X290.0702 Y301.1827
G0 X282.9471 Y302.4629
G1 X283.0283 Y302.9148

Ends up as this:-
G1 X290.0702 Y301.1827
M31
G0 X282.9471 Y302.4629
M32
G1 X283.0283 Y302.9148

I hope I haven’t overlooked the obvious. Any ideas much appreciated as hand editing is a long process on 50,000 lines. I am not sure how to modify the post processor as I have not got to grips with the language style.

Thanks,
Dwight

Here's a quick and dirty solution til Andy sets you up right...

if you have a text editor that with a Find/Replace feature that supports regular expressions (like Visual Studio Express), you can search for "^G0 X.:d*.:d* Y.:d*.:d*" and replace with "M31\n\0\nM32".  You may need to turn on regular expression usage in the options if using Visual Studio.

I know nothing about post processors, but it didn't stop me having a fiddle . I changed the Fanuc post in the way shown (highlighted) in the attached picture. The line is split into 3 because I pressed the Enter key after each command to ensure the G/M Codes had their own lines, rather than being bunched up on the 1 line. You could change your post in a similar way. Picture 2 shows the Gcode file produced with the modification . I'm sure someone will pipe up if this isn't the right way to do it, but it might do you for now.

All the best, Martin.

Thanks chaps, works well, this will do just fine & save much time. If all goes well I will post the new Mortar Plotter here soon for all your amusement.
