Andy,
it sounds to me like you need to further automate the coolant refill
process, with a pump and a remote bulk tank. :-)

It isn't easy to get to the coolant tank on my mill (because the tool
cart is there) so I top up the coolant by pouring it in the top.
It's hard to know when to stop, and also to know when it is low.
So I installed one of these:

Works nicely.
In conjunction with the HAL "message" function I now get a "coolant
high" or "coolant low" message when the machine starts up.
Other versions are available, with more or less range, right-angle
mounting and in stainless steel.
NB. There are two black wires for one switch and two red ones for the
other. It took me a while to figure out what was wrong when I wired as
two red/black pairs.
