RhinoCAM STD vs. PRO

I too started with Cut3D and other raster toolpath software. It was great for a couple of months and I really didn't produce much usable from it. Moving on to RhinoCam Pro, I'm not making stuff I'm proud of...

I think some of the higher end CAM stuff will be coming down in price soon as more hobby users increase the demand.
Tom,

It sounds like you ended up with RhinoCAM Pro after your various CAM experiments. What was it that caused you to jump up to RC Pro rather than the (much cheaper) RC Std? Toolpath editing? Re-machining? And if anyone wants to explain to me what "re-machining" is as compared to plain old roughing and finishing, I'd love to clear up that question in my head as well...

Thanks as always for sharing your experiences and expertise.

-John

Remachining.

It allows you more control over how your toolpaths are formed. You can use larger tools for general area work, then use smaller tools and smaller steps for delicate or detailed areas. In our case the wing saddles, tail mount pylons, canopy edges, etc.

A good example is my latest fuse mold. The old version had a single horizontal (raster) toolpath with a 1/4 ballnose. The edges were scalloped and required a fair bit of cleanup. The new one roughs with a 1/2 ballnose, has a spiral toolpath with a 1/4 ballnose, a 1/8 ballnose remachine (also spiral) for the horizontal pylon, another 1/8 ballnose valley remachine for the wing saddle, a 1/16 ballnose pencil trace for the canopy opening, and a 1/4 drill toolpath for alignment holes, 1/4 endmill for the resin trough.

Total machining time is the same as before (less tool changes but the product is outstanding.

Tom
