This auction does NOT include the machine or any parts. This auction is for the CONSTRUCTION MANUAL to build this machine (drawings, bill of materials, assembly instructions, and supplier list.) The construction manual will be shipped to you on a compact disc containing a PDF file. If you would like to purchase the digital download of the construction manual ($20) rather than a compact disc, please visit our ebay classified listing. Plans are in Imperial measure. Sorry, they are NOT available in METRIC. ________________________________________ ________________________________________ The Momus CNC Router Since 2010, Momus CNC has been providing plans and documentation to construct Do-it-Yourself (DIY) desktop manufacturing equipment. Through innovative design, our mission is to enable builders to construct home-built machines that rival the performance of commercial equipment costing many times more. The design of our compact, fully enclosed, precision 3 axis CNC router can be constructed with common shop tools and skills. Expand your desktop manufacturing capabilities, by being able to machine objects from wood, foam, plastics, and even light work in aluminum and brass. With a 16” x 16” x 5” working envelope, the machine is ideal for engraving, woodworking projects, sign making, circuit boards, making components for R/C cars and planes, and other small-scale milling operations. Create anything from simple engravings, to complex three dimensional forms. The Construction Manual: Version 2.1 We supply the plans, you supply the materials. Our product is a comprehensive 178 page assembly manual that completely outlines the construction of the machine. It contains detailed drawings for every part, exploded view drawings, extensive photographs, and detailed descriptions of fabrication and assembly. In addition to documenting construction of the machine, the manual also includes information on the basics of CNC, software workflow, structural design basics, and wiring diagrams for two popular models of stepper motor drives. The machine is designed to be built from standard sizes of material, and utilizes commercially available components. All required materials can be sourced either locally or through online suppliers. The construction manual includes a complete bill of materials, and list of suppliers. Design Attributes: - low construction cost - ease of construction with simple shop tools - no welding or machining necessary, just basic cutting, drilling and tapping of holes. - fully enclosed - compact and self contained - high level of accuracy and precision - high cutting speeds - highest machine rigidity per dollar - capable of cutting a wide range of materials - competitive with light commercial machines costing many times more ________________________________________ Machine Specifications: MACHINE SIZE cutting envelope: 16” x 16” x 5.5” overall machine size: 32.5" x 26" x 26" Exact dimensions of cutting envelope in the Z axis travel direction will depend on configuration of router mount, length of router bit, positioning of limit switches, and thickness of spoilboard beneath the work piece. The rear of the machine enclosure is equipped with an opening door to allow work pieces that are larger than the bed area to pass through. MACHINE ACCURACY Accuracy: +/- .005” per 12" of travel Repeatability: +/- .001” MACHINE CONSTRUCTION MATERIALS Machine base: Plywood Mechanical parts: Aluminum and steel. The machine is built entirely from standard stock material sizes of plywood, aluminum, and steel. The original material thickness is used for all critical dimensions. Materials were chosen for this design in order to give the highest possible machine rigidity for the cost. No MDF (medium density fiberboard) is used in the construction of the machine, as it is too flexible to generally result in a machine capable of cutting aluminum. DIMENSIONING Plans are dimensioned in Imperial measure. They are NOT currently available in metric. While they plans are not available in metric, numerous machines have been constructed in countries that use metric measure. This can be done either by adapting the plans for locally available metric sizes of materials, or by sourcing materials from the US. The plans include a list of suppliers, many of whom ship internationally. STEPPER MOTORS NEMA 23 frame size. Minimum recommended size: 275 oz./in. ELECTRONICS Uses 3 axis microstepping drive board, and power supply. Emergency stop switch and machine limit switches. DRIVE SYSTEM X and Y axes: belt drive (XL series belt.) Z axis, acme leadscrew with Delrin anti-backlash nut. ADJUSTABILITY AND ALIGNMENT All bearings are provided with micro-adjustable setscrew for precise and easy adjustment. The design of the machine is based around a step by step alignment procedure that allows for highly accurate setup with very simple tools. LINEAR MOTION All axes are controlled by standard ABEC7 bearings riding on cold rolled steel (CRS) rails. Bearing size: 608 SPINDLE The machine is designed to use a trim router, such as the Bosch Colt, or Ridgid R2400/2401. CUTTING CAPABILITIES The machine is capable of machining a wide variety of materials, such as: Wood Plastics Foam Wax The machine is also capable of light duty work in aluminum and brass. Please keep in mind that while these metals can be cut on the machine, there are limitations to their use. The machine uses a high rpm trim router as a spindle, which is intended for cutting of wood and will impose limitations on depth of cut and feed rates when working with metal. Router longevity may also be effected. The machine is also not intended to be equipped with provisions for cutting fluids. COST TO CONSTRUCT Cost to build the machine will vary with geographic location and local costs of materials. Geographic location will also impact shipping costs on those materials and components not available locally. An estimated budget for constructing the machine in the United States is $500. This includes materials to construct the basic machine, but does not include cost of the spindle router, stepper motors and electronics, a computer, or software. Stepper motors and drive electronics typically cost between $200-$600. ________________________________________ Building the Machine: Construction of a Momus CNC router is a substantial Do-It-Yourself project that will require an expenditure of both time and money. The machine is designed such that its construction requires the fabrication of numerous components, out of several types of materials. Construction of the machine can roughly be broken down into three phases: fabrication of metal components, fabrication of wood components, and final assembly/adjustment. Overall skill level required for construction is intermediate. To date, it is estimated that over 100 Momus CNC routers have been constructed worldwide. A vibrant and active community of knowledgeable builders can be found on a dedicated CNCzone sub-forum. Benefit from the experience and knowledge of those who have already constructed machines, and are actively using them. Please find more information about building a machine on the forum HERE. Tools required: The Momus CNC router can be constructed with common hand and power tools, such as those that would be found in a typical woodworking shop. In addition to basic equipment, such as that shown here, a drill press and table saw will make construction significantly easier. While not absolutely required, these two pieces of equipment will make it easier to achieve higher precision and consistency in placement of holes and cuts. However, the design of the machine can accommodate relatively wide tolerances during construction, so cuts can be less than precise without effecting the final accuracy and performance. Metal Fabrication: The metal mechanical parts of the machine can be fabricated with basic shop tools. The standard thickness of the material is used for all critical dimensions, minimizing the need for the builder to maintain high tolerances when constructing the parts. The majority of metal fabrication consists of making straight cuts, and the drilling and tapping of holes. Assembly and Electronics Installation: Final assembly of the Momus CNC router consists of installing the mechanical components to the base, installing the control electronics and wiring, and aligning and adjusting the machine. ________________________________________ To Repeat: This auction does NOT include the machine or any parts.
