This might not be the right forum, but I've got to start somewhere
Here is some code used to control a laser cutting machine, does anyone recognise it?
I'm being asked to 'reverse engineer' it into a DXF file. Before I delve too deeply I thought I'd see if anyone knew what it was and if anything already existed to do the job.

Hoping someone can help

Looks like DXF file format to me.

Looks like what I've hear called "ESSI" format..used by some lasers, plasma,and cutting maghines...

You could be right, if ESSI you might get info on the Burny site, they used it as an option.

Searching for ESSI I found it's associated with ISO 6582 "Shipbuilding -- Numerical control of machines -- ESSI format".

Maybe I should try to get hold of ISO 6582 ?

I am not sure if you will get enough info from the Burny manual, I believe it is still available from the Burny site, It might be worth a shot.

Do you know what the part is supposed to look like or how the laser is moving with this program? I may be able to figure part of it out and draw a DXF file from the code.

Thanks, but there's not one file but a few thousand

I've made some progress and have a VB program that currently reads the file(s) and writes a corresponding DXF file(s) for lines and circles. Now working on the arcs, but the DXF format for an arc is different from this code which complicates things a bit.

We'll get there in the end.
(maybe even be brave and process all the files in one hit )
