How to wire an arduino-based 3-axis CNC machine. Now we'll wire up each of the EasyDrivers.
Remove some of the interior wire from the Cat5 and strip the ends. For each servo you will need two normal pairs of white/colored and one oddball of a white and two colored. In all, you'll have to strip 14 ends. PCB soldering is easy, once you get used to it. There are many other tutorials that cover the subjct. TIP: "Do NOT connect or disconnect a motor while the driver is energized. Next we'll wire the power sources and the arduino. BuildYourIdea.com. 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. The left and lower right boards were milled at approximately the same speed as the Modela. The upper right board was milled at a speed approximately 50% higher than that of the Modella. 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 All of the machine's structure is MDO and is designed to be milled on the ShopBot. Easy to Build Desk Top 3 Axis CNC Milling Machine.
Here is a way to make a computer controlled milling machine.
That puts the real power of a computer control machining into the hands of the average human. Small enough to set on the desk but scalable to any size. As inexpensive as possible without sacraficing accuracy (too much). All most all the parts can be purchased in local retail stores. And above all CHEAP you can be up and running for well under $200. New information on the Motor Driver Circuit is (HERE). CAM Software.

Mini CNC. 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.
I bought a cheapy pillar drill from Screwfix a while back - around £50 if I remember right. It’s a lot of machine for the money: 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! Y-Axis stuff.
