Hello Group;
I am completely new to the CNC world, and have got to the point where I have working stepper motors on a bench. I use Mach3, and the usual hardware. Ultimately I want to create a 3D model in Rhino software, then carve it out of metal or wood on a vertical mill (maybe a gantry router). Typical stuff.
I simply need a bit of clarification on the steps in between. I assume (but please correct if I'm wrong) that I model a 3D shape in Rhino, my favourite software, then save as a DXF file, then convert that file into a G-code file that Mach3 can load and run. Assuming that this is a fairly basic and machinable shape, is my Rhino-to-mill table path correct?
Also, I know that there exists a RhinoCam software that presumably takes 3D models and does all the conversion to a ready-to-machine file, but at $1200 this is too steep for my early purposes.
Is there any free or demo software that can do this? Or, have I made bad assumptions in how I'd approach this?
In the beginning I start with a 3D Rhino model, and in the end, I wish to have the wood or metal shape after it's been machined. Basic questions, I know, but that's where I am for the moment.
Thanks to all who may assist. Tom.
