How's the best way to level the table on the spirit pro? The belt jump a tooth when it over ran the stop switch and bottom out when it sensed a fire, there was no fire...so this is now disabled. I loosened the belt and played with trying to get it back level without much luck. I'm thinking that I'll need to loosen the belt again and manually turn each screw. Would a travel dial indicator mounted to the laser head moved to the 4 corners? Or am I over thinking this, and there is a better and easier way to do it?
