|
| |
|
| *Keep 2 block dimensions same for all blocks | | *[[Image: CNCCMV2.jpg|500px]] |
|
| |
|
| *Based on the conceptual design, 1 of the block dimensions will solely be used to fit the diameter of the leadscrews, precision shafts, and sleeve bearings. | | *[[Image: CNCV2XAxis.jpg|500px]] |
|
| |
|
| *The other block dimension to be uniform will mostly support the part by its length on precision shafts.
| | =Manufacturing= |
|
| |
|
| *For accommodating leadscrew nuts up to 10mm or 3/8" dia, dimension 1 will be 40mm (approx. 1.5")

|
| |
|
| *For accommodating stepper motor mounting and axis stability, dimension 2 will be 75mm (approx. 3")
