Thread: CNC design for consideration

Hi CNC design firend, this looks really good, have a few points to consider on your design:
1) The Y Axis is very close to the X axis (A), going on the diagram there seems to be little space under the X axis for your work piece, (Work Area my sketch) if the Y axis bearing is level with the work table.
2) The Z axis feed drive plate is working outside the bearing range (C), 4 bearings below the Z leadscrew
3) Can't quite see how the Y axix bearings will work (D) assume there are two bars 1 top and 1 bottom
4) It would be better to increase the X axis bearing distance (B) at each end, the wider the stronger, although you will lose some travel distance.
Attachment 5993
The tool stress area is best kept inside the bearing array, if possible.
hope it goes well...
