Hi, Great project, but is there more detailed information available, a schema of the electronics for example Thanks

Dear Friend I have to write one thing about this project. This is a great project and gave me a lot of inspiration for my project. Firstly, I want to ask one question about excel export and serial connection that interrupted by step motor code. How could I handle the synchronized serial transfer with stepper driving? When I tried with Arduino excel software Arduino stepper drive signal is broken by serial connection. Which software do you use for excel data import? Thanks a lot
