It didn't take to long before I learned that myself when we got are new ec-500.I don't know if you can make the air blow longer,but this is what i'v been doing.I will call up a emty tool pocket so the spindle is emty,then just go into mdi and hold the tool release button for a few seconds till all the coolent is out,then just call up the tool you need to change.So what if you make two tool changes instead of one,atleast you don't get a face full of coolent
. Allthough come to think of it that would be a nasty trick to play on someone :devious:,not that I would ever do anything like that.
Just push the button,what's the worst that could happen.
