Just received the HDM! Getting things prepped.

Question for all: the manual says to keep the chiller going for 5-10 min after the spindle powers off. How long are most people keeping it going for?

I just feel the spindle housing & arbor until they are cool. Usually that’s right after it shuts off, but if it’s still warm I’ll let the chiller run. If I’m not using it again, it will air cool.
