| =Block Uniformity= | | =Assemblies= |
| | |
| *Keep 2 block dimensions same for all blocks
| |
| | |
| *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.
| |
| | |
| *The other block dimension to be uniform will mostly support the part by its length on precision shafts.
| |
| | |
| *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")
| |
| | |
| =Stepper Motor Mount Uniformity=
| |
| | |
| *Use the same stepper motor type for each axis.
| |
| | |
| *Nema 17 steppers for appropriate performance characteristics.
| |
| | |
| *Standard 31mm center-to-center mounting holes. Modular.
| |
| | |
| =Sleeve Bearing Mount Uniformity=
| |
| | |
| *Use the same sleeve bearing type throughout machine
| |
| | |
| *2 fastening holes on the part to which sleeve bearing should be mounted. For sleeve bearing of 24mm diameter, mount circle with M5 screws and 1mm clearance should be 24 + 5 + 2 = 31mm diameter.
| |
| | |
| *20mm depth mount holes
| |
| | |
| =Leadscrew Nut Mount Uniformity=
| |
| | |
| *Use the same leadscrew nut throughout machine
| |
| | |
| *3 fastening holes on the part for the nut mounting. For current leadscrew nut, insertion diameter = 12.7mm, mount circle diameter = 19.05mm.
