Mini CNC Subset
flickr:4914251271

Obsolete Page

The subsets have been replaced by kits.
The mini CNC subset is superseded by Structural Kit A and Linear Motion Kit A.

Description

This subset includes components to assemble the mini CNC contraption, as well as few extra components for modifying it. For example, faster belt drives can be used for X and Y axes instead of leadscrews. Other contraptions can also be built from this subset, for example Dremel table saw and routing jig, and probably many others.

Specifications

TBD

Cost

Requires

  • Dremel rotary tool
  • For Computer Numerical Control (CNC) you need NEMA23 stepper motors and control electronics, for example Electronics & motors subset

Variations

Table

  • Standard - 1/4" acrylic table, 1/4" holes
  • Tapped - 1/4" acrylic table, holes with 10-24 thread
  • 3 layer table - 1/4" acrylic top + masonite with embedded nuts + masonite bottom; 1/4" holes (too expensive to fabricate)

Shaft mounts

  • Standard - each shaft mount angle comes with 3 button socket cap 1/8" screws
  • In-house-fab - each shaft mount angle comes with set of 1/8" screws: 3 button socket cap, 2 phillips (larger head) and 2 socket cap (smaller head)
  • With bearing inserts - each shaft mount angle comes with masonite bearing insert and 3 screws 1/4" socket cap
