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

Yes - you can easily have 4 axis with parallel ports.
Any pc can have 2-3 parallel ports easily - mach3 only supports 2.
For your needs, you want a 4th axis.

What sw do you plan to use for 3d ? what cam sw ?

Re - used industrial machine.

Its a good option in the states, and maybe sometimes in sweden but not
likely.

In the us a used industrial machine goes for peanuts i.e. very cheap.
Also in the uk.
Not in scandinavia, they just have never been sufficiently common.

You can build to the same quality as an industrial machine, if you want,
for 1/10th the money.
But it´s still several thousands of €.
