I am having a problem with this CNC. It's working fine when it's cold but after about thirty minute, it gets hot and get an alarm (Bridge RT) and froze the starter and feed hold button. Is anybody getting this experience? Also, is anybody know of a repair service for this kind of machine in Northern Calif. (Bay area) I had heard of a guy that bought the Tree CO when it closed and he is selling spare parts. Is anybody know his contact. Thanks.
