I wrote up a simple program with my Kentech Kipware M software. It transfered onto my Mach3 screen easy enough. After setting offsets and zeroing, I figured I would just hit cycle start and go. I must be missing something, because all I get is a "Bad character used" message. The Kipware default is Fanuc. I think it must have something to do with a step I'm missing between writing program, and transferring it to Mach, but I'm new and don't know what to do. Thanks a lot for helping me with this.
