*Most* botters that I have observed running their machine use this method. The DEFAULT setting for 0,0 is at the bottom left portion of the screen. You CAN define the 0,0 point on the model.
You will quickly learn to do your center cut outs before your outside profiles. When I first started using the machine, I found myself yelling at it, 'What are you doing!!!? You're supposed to start over HERE!' Now that I trust the software, I know that it is going to turn out exactly as previewed regardless of where it starts. Unlike other toolpathing programs, you don't really have to concern yourself where a file starts.no lead-ins.no lead 's pretty much a given that it is going to cut dead on with PartWizard.
and B) Select all vectors and use the transform function to position them close to the 0,0 point. To keep from wasting material or crashing the tool (out of physical boundaries) be sure to A) properly define your material size when starting. If you make a rectangle in the center of the screen, it will cut that rectangle in the exact location that you have it in relation to 0,0 in PartWizard. In PartWizard 0,0 is at the lower left of the screen. You could define 0,0 anywhere on the machine if you wanted to.Note that, just because I start the file at 0,0 doesn't mean that the bit is going to plunge into the material right there. Generally speaking, most files that I run, 'start' at the bottom left corner of the machine, where I define 0,0. Only concern yourself with your material size and where you physically define 0,0 on your machine in relation to your material within the ShopBot operating software. I'm sure there are a few instances where this would be useful, but I haven't had the need to use it yet. To be honest, I never had to define the 'start point' of a contour that I wanted to machine on the Bot.
