Re: [CAD_CAM_EDM_DRO] CNC Flood Coolant?

I was planning to use a windshield washer, in conjunction
with a '555' timer circuit to give me adjustable spurts of
coolant, instead of flooding, 'cause, some jobs, I have a
wet-vac that I use to suck up chips as they're being cut...
getting the swarf outa there keeps the finish better, and
extends the life of the cutting edge. as far as being O.T.,
I plan on using my M07 relay output for the intermittent,
and M08 for continuous, with M09 shutting off both relays.
