Hi adimar, I'd be happy to help. I moved your post to a new topic since it is different than the other one.

 

Here's a schematic for the L297/L298 stepper motor controllers I designed for my CNC machine:

You can download the Eagle Layout Editor schematic & PCB here: http://www.foxytroni...-schematic-rc2/

 

Also, here's a website with a lot of great information on the L297 and L298: http://pminmo.com/

 

Let me know if there's anything I can help with!

Hello thank you very much for drivers motors is very helpful I managed to build it and make it work it.

The next step is to develop an interface with the computer I was going to use arduino uno and type CAM program to generate G-Conde.

I would like to know how you managed to do it with CNC control computer.

Thank you so much for everything

Great, glad to hear that you got the motor drivers working!

 

I wrote a C++ application using the Qt framework to control my CNC machine. It's available for download here: http://www.foxytroni...cnc-controller/

 

If you have experience with C++ then you should be able to adapt that program to meet your needs.
