The screw on the locking cam is adjusted as tight as it will go and still allow router movement. There's no dust between the pinon and gear or housing, I clean that out every time I insert a bit. I've adjusted the router up to the correct height in an attempt to get rid of the backlash/slippage. It's a fairly new router. I never had this issue with my old router that I continually removed from the base to use as a handheld. Maybe I'll go back to that one.
Any suggestions on what more I can do to stop the slip? Or what other router & base I could get that wouldn't have this problem. Now I don't want to use it again for for fear of it slipping again and ruining the top and ends (again).
