Just started a carve this morning. After 2% of a carve, the machine shuts down and the reading on the screen is Power Fluctuation. Press enter to restart. Runs for about 2 minutes and shuts down again. Now, it is not storming outsides and I know that the electrical wiring in my garage is fine. It is cold in my garage and I know that there is a temp. min. for using the machine. I kept the machine in the warm house prior to use and that has worked in the past. Just turned the garage heater on now to see if it helps. Is there anything else I should be looking at? I don't want to scrap this piece of wood and start over not knowing if this will happen again. This is supposed to be an 8hr carve and I would be wasting a lot if I stopped.
