This morning I CS'd my 4020 machine. I went to change tools away from my probe to a small tool so I could warm up the spindle. I have a new spindle so sometimes the tools get stuck in the taper pretty good.

The machine moved the tool umbrella over to the spindle, I heard the tool break loose from the taper, but then the machine seemed to put the drawbar back in, and moved DOWN. this pushed the tool holder right down thru the tool carousel. The tool stayed in the spindle. There was a Z axis overload and e-stop.

I pressed jog, the tool changer moved back home, I pressed tool in/out to get my probe out of there, and I then CS'd the machine. Now, the carousel doesn't line up with the spindle. It is bent. You can see that some portions of the carousel are higher than others if you index through all 21 pockets. its bent maybe 0.125"?

I'm going to take the carousel off and inspect it.

what the hell happened here?
