I'm liking this program. This in combination with the ezcam online thing I found may allow me to make a good program or two of my own. One problem I'm having with the CNC simulator though is getting my part on the block. The demo codes provided with it always run right in the bock, but my code always runs way outside. Is there some setting I'm missing. I messed around with the block size and inch/mm settings but I think I might have messed it up even more.

I've had trouble with the mm setting in CncSimulator too, so I just avoid it, since I have an ANSI CNC mill anyway. As for the part's alignment, the CncSimulator will ignore most of what it doesn't understand, so make sure that the output of your NC code generator is non-modal and doesn't use variables. If the intersection of the lines created by part's bottom-most and left-most points is not at the origin, the NC code generator is to blame. Make sure you shift (or translate) the part in the code generator so that the above mentioned intersection is at the origin.
