Breadboard ends and router issues

I've lost all confidence in my PC 892 router and a 8901 fixed base permanently attached to my tablesaw insert. The router slips down after it's locked and in use. I've ruined 2 sets of bread board ends because of this and the slots in the top had to be cut off.
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).

The big question is "why is it slipping". See if you can make it slip on the benchtop where you can see what's moving and maybe figure out why.
Porter Cable makes an accessory for that router for router table use--Item 75301. Whether it will address this problem I have no idea but it's about 30 bucks.on Amazon.
Beyond that, look into a proper router lift--JessEm has one for about 180 bucks or if you google "DIY Router Lift" you'll find some ideas of how to cobble up your own.

Yeah -- The combo kit came with that (75301), it's a height adjuster on the top. I ended up tightening the screw as much as I could and still have the router adjust and the cam lock. I got acceptable results, not perfect but acceptable. The moral is to check router bit height a lot to ensure that the router isn't slipping down.

I once had a similar problem. I bit the bullet, bought a Triton plunge router, and mounted it as a table router in my table saw extension. Problem solved. One of these: (Amazon.com product link shortened)33025257&sr=1-1&keywords=Plunge+router&refinements=p_89%3ATriton
