  1. Sticky: Re: GrblGru: Free CAM and 3D-Simulation for mills and lathes

    This is the update many of us have been waiting for. Finally a piece of affordable hardware that's widely available and easy to configure. I've got a couple of boards arriving today just to test your...

    Re: NEW MILL TURN ARRIVED

    If you have the money it's a no brain choice to go with the "works out of the box" machine rather than the bubble gum and bailing wire version of a cnc. If you don't have the money I'd suggest start...

    Re: NEW MILL TURN ARRIVED

    Shopmaster might have thought that at one time also. I don't think things quite worked out that way. You still have to have a good product and great customer support otherwise word of mouth will kill...
