Re: Looking for a good code simulator.
OpenSCAM is a dead name. The latest version is called CAMotics. Its got some little things like parsing machine specific codes like G28 and G30 weirdly, and it doesn't process G83 for peck drilling, but otherwise it seems to work for most of my needs. It does show non peck drilling and spiral interpolation drilling ok.
If you are a CamBam user there is even a user written plugin so you can create a compliment file and simulate in CAMotics quickly and easily.
Its open source I think so if you are a programmer and interested in helping... also the original author is motivated by donations. He fixed a couple things I mentioned after I made a small donation. Another time he asked me to do a project on one of his project sites and he'd add a feature I asked for. He's responsive to people who are not just one way.
