In the CNC profile cutting drawings, have you mentiond how many units are required from each drawing. For instance if we take the motor mount drawing how many units do we require . I assume that it should be 6 units. |

Why do you want more motor mounts than motors? 
Okay, I must plead guilty in getting all that information out slowly  . Also, with the development on the z-slide (to throw out the expensive linear bearing) there are some more laser cutting shapes to come. (3 shapes, qty 1 each)
Anybody who has already ordered laser-cuttings will have no scrap, unless they ordered too many pieces. If the quantities are not clear to you please ask.
I used 5 motor mounts (2 for x, 2 for y and one for z) but a MechMate only has 4 motors. The extra mount on the y-axis is just carrying a roller. I suggest that you order 4 mounts, this gives you the option to have double Y-motors later, or to use the same spring roller that I used. If money is tight, order only 3 mounts to the published drawings. (The z-axis mount will be a different shape) |

I was thinking of handing over the total job to the CNC cutting facility by Monday. It is better if I could get everything done in one go. The cost would be cheaper if they could quote for the total job in a single go.
I was thinking that you need 2 mounts for the x rail, two mounts for the Y rail (including one dummy) and two more for the Y rail (the max you will need since you have not perfected the drawings). |

After assembling the z-slide today, 3 profile drawings were revised. (This is the risk of publishing drawings while still prototyping). One could get into the lazy habit of saying it is too much trouble to improve a design because it is too much work to re-publish a drawing. |

Do I need to have AutoCad to open up the profile drawings that are in "dxf"? Can I use something else to open them that is free? |

You have the exact same drawings in .pdf format as well.
But, in general, if you are interested in CNC, you almost certainly must find a way of opening .dxf's |

Check out CAD standard. Still, it may fail to import some DXF...
You may want to see if SketchUp handle 2D DXF nicely...
or you may Google for a DXF viewer. I'm pretty sure you'll find many. |
