Re: [CAD_CAM_EDM_DRO] Re: How to convert a Grizzly 1006 Mill to CNC

Hi Hannu
I realized that I didnt answer your question about what software I am using.
For general modeling Rhino4, for more freeform modeling Maya, for cam I use
rhinocam and someother sw that i am testing out.
I also try to learn Solidworks and Autocad and a bunch more to see what
works best.
Been looking towards VisualMill, but if you like some other sw that you
think would workout pls let me know.
And for the control of the router I think I go with Mach3 since there is so
much people working with it.
best regards
Per
