MorganS:
"Using" is a strong word: the slave programs shown so far still don't do anything with the data so it's a Shroedinger's Cat type of problem.I think the original advice (from elsewhere) was flawed: this appears to be a distributed manufacturing project and I2C won't work at all if the distance between the slaves and masters is more than a meter. Maybe it's for very small 3D printers?
I actualy want to build a cnc machine and use Arduino as controllers. As i can imagine the distance of Slave Arduinos won't be up to one meter but the distance of Master Arduino from the Slaves would be greater than one meter. How could this be a problem?

I can't help feeling that you are a little confused.
The truth is tha i'm a bit confused that's why i asked help from you.
