Hi,

I am new to this forum. I am just starting with Arduino and want to convert my small mini lathe to two axis simultaneous CNC capability using stepper motors.

What Arduino model should I consider for my project?

I want to learn by playing with it before doing anything to my lathe.

An Uno would be perfectly capable and it is the best Arduino to start with because most programs and add-ons work with it.

For a CNC system you may wish to use the GRBL program.

I am just starting with Arduino and want to convert my small mini lathe to two axis simultaneous CNC capability using stepper motors.

So you are a beginner and want to do a very advanced project.

May I suggest this is too much for you at the moment, until you learn a bit more.

Here is my CNC project, if you can understand it then you are welcome to extend it to your conversion.

Yes. This is not a first project

I added 3 stepper motors to my small lathe using my own Arduino software on an Uno and a Python program on my PC to act as the user-interface. I do as much as possible of the computation on the PC and all the Arduino has to do is implement a given number of steps in a given time.
