Hello,
I have written a free-to-use script that turns AutoDesk 3DS Max into a very basic CAM software to generate KRL for the Kuka Robot (Youtube Video below):
Thanks got to Rab Gordon. A few years ago, he wrote an open source script called CNC Toolkit for 3DS Max. It did not generate KRL, but had some really useful functions that I shamelessly used in my software.
I have two versions of the script, one for a robot equipped with a hotwire and one for a Robot with a CNC Spindle. The software is beta and VERY basic (so no spindle speed control or tool changes.) It is only about generating a tool path with multiple passes, custom step over and surface normals. It is also only for simple surfaces (no under cut and no bottom faces). I already have one friend in London ready to beta test it, but would like more to test it (at your own Risk!).
If you have 3DS Max and a Kuka Robot and are willing to beta test the software, please contact me at wassim dot jabi at gmail dot com and I will send you the MAXSCRIPT to test.
