Sorry if i asked such a simple question.
Will the Arduino need to be plugged into a power supply if I was to disconnect the USB cable from the Arduino to my computer?

I'm using a Radds 1.5 and an Arduino due.

No, the Due will get its power from the RADDS.

Ah, thanks for the reply.

Again, I'm not considered an expert in how circuits work but how would one then manually calibrate the whole printer if it requires a computer connection via USB. Wouldn't the two power sources overcurrent the Arduino?
