Block Uniformity

• 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 accomodating leadscrew nuts up to 10mm or 3/8" dia, dimension 1 will be 40mm.

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 10+15mm washers and 1mm clearance should be 24 + 10 + 2 = 36mm diameter.
