I crashed my machine today, not horribly but bad enough. Now I have a knocking sound coming from the spindle. It stills spins ok, but makes a knocking sound. Bearings maybe?

Re: G0704 Spindle noise
Could be a bearing.. also could be a gear. If you haven't put a belt drive in it the original drive gear is plastic intended to go before something more serious is damaged in a crash.You could have busted a tooth or something. If you do have a belt drive on it check the belt for a burn spot that can happen if the motor pulley keeps turning when the spindle isn't!

Re: G0704 Spindle noise
Mines been belt drive for so long I forgot all about the gears. I damage the bearings in my spindle once, it wasn't noticeable when turning by hand, but there was an obvious noise when turning even at low RPM via the spindle motor.

Re: G0704 Spindle noise
I would suspect the gears. Remove the top green spindle cover and inspect the gear that the motor turns. That one seems to get the most punishment and is easily damaged. I suspect that a tooth or two are missing. Oh, you will also have to remove the motor and top plate. Here is a photo of mine before the belt conversion.
