seeking design modesl for tabletop CNC machine-

Looking for some plans for building a diy cnc platform. I have sourced the electronics, but just needing plans and parts scoping to start the project- metal or wood as this will be a student build. will be using v-carve programs donated by manaufactuer

There are many option of CNC machine can be choose, with various advantages and disadvantages.
Before making a choice, we need to set what we want related to the capabilities/advantage feature that can be done by the CNC machine, including:
- Type of Material to be processed (Steel, Aluminum or wood). to process hard materials like Steel, requires CNC machine with a more rigid structure and a larger spindle motor torque.
- Desired level of accuracy/ precision. High precision CNC Machine, more accurate driver systems, such as Servo Motors, but servo motors are more expensive and control systems are also more complicated which requires a better controller (Close loop control system), but if not need high accuracy we can be used Step motor where the price is cheaper.
But today there are new technology that use of the latest digital stepper drive technology allows stepper motors to work with high precision at extra smoothness, while we still use the Step motor. Using this kind of stepper driver with multi-stepping feature allows a low resolution step input to produce a much higher micro-step output for smoother & quiet motor movement
