DNM 750II Thru Spindle Coolant not purging.

[Machinistsss]

Hello guys, I have one very annoying issue when using the thru spindle coolant on our DNM 750, when I finish running a tool with it turned on the coolant gets trapped behind the tool.
In a perfect world I would never have any coolant touch the taper of my tools because this can lead to stickiness that simply doesn't happen otherwise in the pockets.

When I tool change about 12oz. of coolant comes flying out all over the place, even if I blow air through the spindle to try to clear it out (M114)

I especially do not like coolant getting on my probe as the stylus picks up dirt easier when it has any traces of coolant on it.

Has anyone else experienced this and know of a fix?

Thanks for reading!

A certain amount of coolant will remain after TSC usage. Even brand new machines do that.
