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: https://www.amazon.co.uk/Plastic-Liquid-Sensor-Double-Floaters/dp/B01EZZKM8U/ 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. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
