So, I don't hang a lot of board at all. But I got a roto zip because I have a bunch of recessed lights to do. So, I am not good at running this thing. I believe I have it setup correctly. Hanging 1/2" blue board. I have the bit set at 5/8" and I'm using a guidepoint bit. The bit is still digging into the rim of the can though at times. It also seems to be overheating, which I'm sure means I'm going to slow, or pushing to hard. I'm assuming if the bit digs into the can rim that it is set to deep, but I'm afraid if I set it any less it won't find the lights at all. I am running the thing counterclockwise. Any tips or hints for what I am doing wrong? Thanks, Nick.
