I have a problem with routerbitworld sent them an email, no response was required at all to get my marriage board to show up on my axion pro, never had one Problem, but I saw that the tracks were burned on the plow board, stopped the machine and found that a tooth had broken off. All my holes we drilled and there was nothing on the plow board to indicate the car had hit a propeller but not responding to my email is not cool.
