	~~=CAD of Mobile Gantry Design (In Progress)=~~

	~~[[Image: cncgantry.jpg]]~~

	~~=X Axis Frame Design Rationale=~~

	*The major functions of the X-Axis Frame are to provide a flat working platform on which to rest boards to be milled, and ensure the rigidity of the X-axis precision shafts and leadscrew.

	*Start by assuming that the x-axis frame needs to support a pair of precision shafts and allow mounting of the working platform and stepper motor with leadscrew.

	*The working platform has to be some sort of flat sheet or plate.

	*Some sort of rectangular support structure seems a good start, with a total part count of 5.

	*Here is an visual example using 1 plate and 4 rectangular bars:

	~~[[Image:RectBar.jpg\|500px]]~~

	*This is rigid and has space at the sides for gantry mounting, but bulky. We notice that a lot of material is still being used despite the low part count. Keep in mind that part count and material volume, future design implications, and ease-of-manufacturing must all be considered separate, though interrelated factors in effective design.

	*If we use only 2 rectangular bars (for supporting the precision shafts), then we can save on material volume by using 2 angles as structural supports.

	*Here is an visual example using 1 plate, 2 rectangular bars, and 2 angles:

	~~[[Image:2Angle.jpg\|500px]]~~

	*This is relatively volume-efficient, with plenty of open space at the side for gantry mounting. The major concern with this design is that the resistance to force vectors is heavily dependent on the angle supports, which significantly lose mechanical advantage as the rectangular bars get taller. Low-profile setups will be best for this design.

	*Here is another take on the 1 plate, 2 rectangular bar, 2 angle setup. What if the angles were to mount the precision shafts instead of the rectangular bars?

	~~[[Image:2MainAngle.jpg\|500px]]~~

	*The major concern with this design is the vulnerability to forces with strong vectors along the horizontal plane. Again, low-profile setups will be best.

	*For completeness of the practical variations of the 5-part x-axis frame, consider the use of 4 angles and 1 plate:

	~~[[Image: 4angle.jpg\|500px]]~~

	*The major concern with this setup is that the angles, though volume-efficient, will not provide enough rigidity at their 4 junctions.

	~~=Gantry Design Rationale=~~

	*The gantry needs to be mounted at 2 points per precision shaft for stability, as well as somehow being connected to the movement of the leadscrew nut.

	*Starting from the x-axis, assume that the 2 precision shafts and 1 leadscrew are firmly mounted. One C-channel per precision shaft gives us the 4 contact points necessary per axis; 1 angle centred at the leadscrew and across the C-Channels can make the connection. A flat bar for the C-Channels can provide rigidity along the plane perpendicular to the precision shafts.

	*Here is a visual example (note that the square bars should be seen as round instead):
