 +Note you can connect several different power supplies at the same time, with no issue at all, Smoothieboard has diodes on-board that will simply get the power from the one with the highest voltage, meaning you can even turn one off and the other will be used without a reset.
  
 If voltage and current are strange concepts to you, it's probably a good idea before you continue setting up your board, that you read [[https://​learn.sparkfun.com/​tutorials/​voltage-current-resistance-and-ohms-law|this introduction]]. If voltage and current are strange concepts to you, it's probably a good idea before you continue setting up your board, that you read [[https://​learn.sparkfun.com/​tutorials/​voltage-current-resistance-and-ohms-law|this introduction]].
