The Mini CNC project is a complete set of plans and instructions on how to build a 3 axis CNC machine that is functional and also precise. The Mini CNC is very simple and easy to build and if you have all the materials and parts prepared you should have it ready to work in less than 5 days.
I wanted and also needed to build this Mini CNC machine so I can make faster and more precise the parts that I need for my other home projects.
Step 1: Mini CNC specifications
The working area of the machine is X=450mm (approx. 17.5 inch) and Y=250mm (approx. 10 inch) and can mill parts as high as Z=110mm (approx 5 inch).
The maximum milling speed on X an Y axis is 2400mm/min. and on Z axis is 1800mm/min.
The resolution of each axis is 1/50 or two hundredths of an mm and one axis revolution means 4 mm of movement.
The router used for this CNC is a Kress 1050.
The number of parts used for building this Mini CNC machine is 42 excepting screws and nuts.
Step 2: Required tools and skills
For this project you will need to have a set of screwdrivers and a set of hex keys or Allen keys, a drill for some extra holes, metal cutting saw to cut some custom parts, soldering station or soldering gun join the wires so they`ll have a good conductivity , and a multimeter.You should have knowledge of basic electronics, how to solder and how to use a multimeter
Step 3: Ordering components
The trapezoidal cylindrical nut was made in a local workshop.
