Recently received my nm145. When I manually turn the coolant flood on in Mach3, I hear a relay click, but nothing happens (pump doesn't turn on). The coolant light in Mach3 lights up blue but it blinks. Should it be solid?
Now that I look in the mach3 ports and pins, it shows charge pump on pin17. But on the circuit board in the mill, nothing is connected to pin17. It should be...right? Or is there some other cross connect somewhere? I'm an idiot when it comes to electronics and wiring in general..
thanks to a helpfull forum member, this is now fixed. pump was wired backwards from factory.
