Hey,
What would cause the sliding plate to move on it's own. I was carving a project which carved fine. when it went to cut the carving out the machine whent through finding serfice it asked to reset sliding plate. When I looked it was at the other end of the machine. I know I slid it against the wood in the beginning, cause I always check if the board will slide easy before I lower the top of the machine.
Thanks, Mike
