I was using my variable speed PC690 in the fixed base on my DeWalt track saw track to cut big rabbets for a goofy little project - putting a door in. That should be a simple project but when they added the dining room to our house (previous owner) they did not take down the brick or exterior wall. So I had to have either a 14 inch thick opening or take down a lot of brick and a wall. My wife couldn't bear the thought of a 14 inch wall so I had to do it the right way. And now I have to put a subfloor in that is at the right height for the hardwood to run from room to room. The two rooms are not quite at the same elevation at this doorway. And the subfloor is different thickness in the two rooms. So the new subfloor has to account for this.
Anyway, anybody with experience fixing the variable speed on a PC690? I have a single speed motor too which I used to finish but I would like to have both motors functioning correctly. The variable speed one will turn but not at full speed, regardless of where the control is. I have four bases for these routers so don't really want to use this as an excuse to get something different.
