My shopbot is 220 so that is probably not the issue. Could it be your USB port or line? Do you think it is a communication issue or a power issue? Do you have a way to check the temperature inside the box, like with a laser temperture gauge or? Then ask shopbot what the regular operating temperature should be.
I have operated mine in a hot shop in the summer with no issues. I think you need to determine first if it is a communications issue or temperature issue first.
