I am planning on getting those water cooled chinese spindle..
With some simple pump and im concerned if my pump fails for some reason.. and the spindle keep turning without coolant inside.. and breaks the spindle..
anyone use some kind of switch that sends some signal to breakout board then it will "pause the cut (retract and then shut off the spindle
any terms for that kind of switch.. tried looking up cant find what im looking for..
Thanks
Dan
