Hey All,
I am in a really urgent need to work out my DIY printhead with a stepper control and thermocouple reading. My problem is since it is an open circuit, I probably get an electrical noise and the easy drive for the motor prevents the temperature reading. So as a really fast solution(since I have to present the machine working), I will try to use two different arduino boards which don't share the ground or any other wires in between them. Is there a way to trigger the signals in the same code though? Lİke working with two serial ports in one Arduino code?
I need an answer ASAP?
Thanks,

Good luck with that.

You can use 2 (or more) Serial ports from an Arduino but is it more Serial ports that you want/need ? Which Arduino are you using ? Can we see your circuit diagram and current program.
Removing direct connections won't help a lot, noise tends to spread through air as well.
It may help to keep the motor supply and driver isolated from the other circuits, by adding opto-couplers between the Arduino and the motor driver.
Can you not simply read the temperature in between steps of the motor? it may seem like the steps are really fast to you but the Arduino can take many readings in that time.
