if the voltage is set wrong, the motors could be missing steps periodically, making it look like it is making random movements all over the place.
voltage too high will cause overheating and temporary shutdowns.
voltage too low will result in not enough power to move properly.
If he replaced the board with the same type as the original then it is a Makerbot board also known as a Mighty Board and he does not have the ability to do that since voltage and current are both controlled by the firmware and they have that adjustment locked out from the user. In fact there are very few adjustments he can do.
You can't even send gcode commands to it as it does not communicate like a normal board does. All gcode has be processed into a file called an X3G file which is unique to the boards that Makerbots and their clones run on. His machine is just like the one I have no that I converted to open source. That Makerbot board and it's limited options was my main reason for doing so.
Below is an image of a Mighty Board. His machine like mine is actually a clone of the Flashforge Creator Pro if it was made by CTC and the Flashforge is actually a clone of the Makerbot.
His only other option for a bit more control is to flash Sailfish firmware but even then he is still limited in the fact that all communications to the board has to be in that X3G wrapper. The better option would be to convert his using one of Panucatts dual extruder board or any of the other open source dual extruder boards out there. Then he has an ordinary open source dual extruder printer that he can use Marlin or Repetier firmware on and use Repetier Host, Cura Host, Simplify 3D, Craftware, Pronterface or any of the several other host out there.
