I have been programming CNC Machines for many years and also teach EIA G-code programming and set up at a local college. Over the years I have used this post format for the mentioned machine as a safe reliable post for the safe operation of cnc mills. It only requires a few tweaks to have it work on a machine requiring G30 home commands for tool changes and pallet change operations. it is neat and tidy looking wich many many machine operators have thanked me for, and it is easy to find "the next tool to run" in a safe manner. Each tool starts and ends with a with the basic same format, each tool is self-contained for safety. 

Look at it and give me feedback and possibly someone can build a better post that is universal to use.

here is an example

I'm usually the guy that says, screw the looks of a program as long as it works.

But of course everything has it's limit.

Making a post in a way that you can start anywhere you want in the program is good. Not usually the case with out of the box posts but I would be all for having an option to do that.

This line though, is very confusing to me:

M06 T1 (1/2 FLAT ENDMILL .02 RAD)G54 X-1.7248 Y-2.541 S7500 M03      start of tool lines

No way you can easily see what is going on at the machine

I would always change it to this:

M06 T1 (1/2 FLAT ENDMILL .02 RAD)
G54 G00 X-1.7248 Y-2.541 S7500 M03      start of tool lines

Basically that is the same thing minus the G0 line

@Anonymous

Yeah basically the same thing but much more clear in my opinion.

Just using your "Look at it and give me feedback" line in the idea.

But I don't think I will have the time anytime soon to do this. So let's hope Autodesk or someone else will chime in on this.

I do too. So many post are so different, but a semi universal post is much
easier to maintain and modify. Safety is number one and I have seen many
post that do not support this but rely on operator intervention Wich always
leads to a crash

Oops the line in question is a typo....
Should be
M06 T1
G54......... And so on....
