2x 50cm threaded rod or any kind of rod 6 or 5mm diameter depending on the pulleys inner diameter.Spacer Nuts ………………………………… Amazon / Banggood / AliExpress.So make sure you consider this when 3D printing those parts. Therefore, in the STL download files, I also included two versions of the shaft couplers and the mounting brackets to mach these dimensions. Here I’m suggesting to use 5mm because these dimensions are more common and can be easily found. Note: In the video I’m using 6mm bearing as well as threaded rod and GT2 pulleys.

Here’s a list of all main components used in this CNC machine. For testing patterns, small deviations were shown for testing the sides of each pattern, but slightly larger deviations for the experiment about 0 coordinates.See also Best Budget Friendly 3D Printers for Beginners and Hobbyists Assembling the CNCĪnyway, now I have all the materials ready so I can start assembling the machine.

For testing the age of concrete, the highest accuracy value was obtained when the age of the concrete reached the value of 1 h. The accuracy of the machine was tested by comparing the results of machining the workpiece with the design on the computer. The CNC electronic components are arduino, CNC shield, stepper motor driver and stepper motor. Workpiece dimension is 200 mm × 200 mm × 30 mm. The workpiece used is concrete with a composition of cement and sand of 1:2. Machine materials are selected from metal, wood and nylon. Assembly begins with the assembly of the base and column frame, the table with its components, and the spindle arm and its spindle. Machine production begins with frame welding, spindle arm welding, crafting table, and component purchasing. The design of the vertical component includes the analysis of the frame, and the spindle arm. component includes analysis and selection of x table, y table, linear drive system, power screw, and motor. The machine components are grouped into two main parts, horizontal and vertical parts. The research is carried out to develop a concrete carving CNC machine.

A machine is required for engraving concrete, that the engraving process can be faster and easier. CNC machine is a machine that can operate automatically through processing commands performed by a computer.
