Scratch that, did not realize it was a foredom, I thought you were speaking of a GRS handpiece I miss read it, not sure who can help you on that.

Could be a bent or out of true cutter putting strain on the rest of the system.... does it do it with all collets and cutters?

Did you go to a differant motor recently ? the Fordome needs to be run on the lower RPM motor ( the LX ) its a 5000 rpm motor made for the engraver, the SP is a higher RPM motor(I think its 18,000 RPM ) it will overheat and burn up the engraver. The reason I asked if you changed recently is because of the previous 18 month trouble free performance.

What kind of lubricant did you use?
