Sometimes my 7518 can't control the lowest speed. It spins way too fast and then slows down to under 500 RPM before speeding up again. I'm trying to run a panel bit (3-1/4") and need it to turn SLOWLY. The second lowest speed is consistent, but I want to use the slowest speed.
Anyone know of any tricks to fix this at home? do you know how much the defective part costs? Is it a logic board or a sensor? I called PC last year about it and they said they know that model does that, but this is ridiculous because it'll go FULL speed, which is scary with that large of a bit on it.
