    Machining wands for Halloween (4-axis CNC)

    https://www.facebook.com/watch/?v=799815877521552

    Talley Boatwright shared this video about the DeskProto CAM software on Facebook. He is creating Harry Potter style wands for Halloween.

  3. Re: 4th axis machining below the rotational axis

    Hi Andrew,
    DeskProto can surely dip below zero when rotary machining.
    When checking "Use rotation axis" the minimum Z limit for the Z by default is set to 0.0 (Part parameters, Material block...
  4. Re: 4th axis machining below the rotational axis

    DeskProto can indeed do that: the part rotates while cutting.
    This is even possible using a helix-shaped toolpath: one long path around the complete part.

    Re: Creating accurate toolpaths for 4th axis

    A next useful source of information is the DeskProto Tutorial book, available at the website as PDF.
    One chapter is completely about rotation axis machining.

    Re: Spherical Void - Too Shallow

    Hi Greg,

    Indeed the ball in your example will not exactly fit the hole that you machined, for a few reasons:
    - the STL approximates the real sphere using flat triangles, making the hole a bit...

    Hi Greg,

    Not sure what you mean with "center the area".
    Positioning of the part on your machine is done using the WorkPiece zero point.

    Hi Greg,
    These toolpaths are for a ballnose cutter.
    Such cutter needs to go R mm (R=cutter radius) deeper than the bottom of the part in order to create vertical walls there.

    Hi Greg,
    The area where no geometry is present is called the Ambient area.
    You can use the option "Skip ambient" in order to skip that.
    That will also skip the area around the ring though.
