Hi
I have recently moved from another tool that has just changed its terms of use and am totally impressed with FreeCad.
I am also fairly new to the world of CNC and so please be understanding.
I have a home build standard 3 Axis machine running GRBL 1.1f from an Arduino UNO.
However as far as I can tell this setup will only do 3 Axis.
I want to CNC cylinder shapes with grooves, extrusions and pockets and so I thought I could unplug and immobilize either x or y and use this as a rotary axis. (I have seen others run there machines in the same way)
However can I produce the CAM for this from FreeCAD - I have read a lot of the 4th Axis posts but I am thinking what I am asking is not true 4th Axis.
Are there any Addons or Macros that can unwrap a 3D object (like another well known program does) so I can then fool my CNC thinking it is still running as a 3 Axis machine?
Will the work being done on on the 4th Axis work in the way I want?
Any tutorials as to how to use FreeCAD to do what I want?
Thanks
