MAS 863 - David Carr My final project is a 3-axis CNC milling machine that costs less than $100 (currently $87) to build. It can mill PCBs, wood, and even mild steel. These PCBs were milled using the machine. The traces are 10-15 mils. Some more test pieces: MDO and mild steel with a 1/32 inch mill on the left, wax with a 1/8 mill on the right. Design My design was heavily influnced by Johnathan Ward's MTM-AZ, although it shares no common parts with his machine. Machine drawings (DXF) Bill of materials Brute force stepper driver The brute force stepper driver is a simple 3 axis stepper driver for use with EMC2. Here are the files for milling the board: Bottom (PNG) Holes (PNG) Mill the first/bottom layer with a 1/64 inch mill first. Components MDO frame Y,Z axis gantry assembly Bed and X axis assembly Spindle assembly Stepper motor drive board PC control software Processes All of the machine's structure is MDO and is designed to be milled on the ShopBot.

13x13x5~Solsylva CNC Plans Designed to be as simple and inexpensive as possible. 13 x 13 Fixed Gantry Machine. Easy to build Low Cost All homecenter parts Built with basic tools All materials in this table were purchased from the local Lowes, with the exception of the drives and steppers. The cost of the homecenter components was ~$120. The plans include step by step written directions with photos and dimensioned drawings of the components. Made of 1x4 and 2x4 boards. The machine uses basic materials with a minimum of waste. Its body is made of a 2x4 and a 1x4 that are cut to length and drilled. The rails are all cut from three 36 inch steel rods with no scrap. Tool list (on FAQ Page) Materials list.pdf Simple flexible design. The table bed can be made of a 15 x 15 inch piece of plywood, MDF, or plastic. Inexpensive off-the-shelf metal clamps and straps are used to hold parts in place. The machine has a 13 x 13 x 5+ inch cutting volume, but it has a footprint of only 18 x 25 inches. Pattern carved with the 13 x 13.

Hot Glue Gun Extruder for Your CNC Machine or 3D Printer 3D Printing still costs a few dollars and may be out of reach of hobbiest who do not have any budget. The goal of this instructable is to construct an FDM (Fused Deposition Modeling) printer extruder (a key component) using a $3 Hot Glue Gun. If you don't think you have seen an FDM machine, you probably have. There are many hobby versions out on the market now ... Think Up! There are many parts to a FDM printer and in this instructable I am going to concentrate on the extruder. Before I get any further I would like to extend a big "Thank You" to the open source community and all of the people who have contributed to the 3D printing community. So let's get started shall we. Just in case you want to see it in action before you do some reading, view the video below. Apple Logo (the one with the bite out of it) The apple turned out the best. Yay!
howie m » Amateur CNC mill show and tell Friday, November 19, 2010 Amateur CNC mill show and tell Thought I’d have a go at something a bit mechanical for a change. Mmm… precision drilling… mmm… OK, back to me: CNC mills are all the rage at the moment - loads of people seem to be building them, from huge ones through to tiny little ones you can knock up for very little money. I’ve got loads of electronic junk in boxes, so I had a dig around. It’s a scanner - a disco/nightclub light that can change colour and, using a motorised mirror, shine the beam around the room in carefully choreographed patterns. These things are the heart of a CNC machine - you can control precisely how much its shaft rotates, unlike a normal motor that spins freely when you give it power. I managed to scavenge a load of bearings and rods from old printers. I bought a few lengths of leadscrew from Marchant Dice (yay! I also bought a matching tap, to make the nuts that’ll be driven by the screw. Drill a hole in it: First: X-axis stuff Next: Z-axis stuff
Combination CNC Machine and 3D Printer How to make your own 2D CNC machine that converts into a 3D Printer and back to a CNC machine in less than an hour. Costing less than a CNC machine or 3D printer! (~$1,000.00) In addition, the design will go further than the traditional 3D printer printing ABS/PLA, and move forward to printing with new materials such as 3D Printing Nylon derivatives like tauman 618 as well as Acrylic and PET. Latest Updates to this Instructable as of 9/12/2012: 1. There is a full 2BEIGH3 update here, along with a source for Nylon 3D Printing material here. 2. As a sample of the unique new properties of just one of these new materials, Here is a 3D Print of a Childs NYLON Prosthetic Insole on the 2BEIGH3 3D Printer. With the 3D Printer configuration of the 2BEIGH3, you will be able to print parts that meet much higher standards for strength, flexibility and pliability.
