I have been working on several different designs for the fluid transfer system on this machine.
This system would use two pumps. ( I have the pumps, so it is not a problem with the expense of them). I also have a high level sensor that will shut the fill pump off if the tank gets too full.
I had a fluid spill from an EDM (which, naturally, was working unattended)
once, and it was a mess. If possible, my preference would be for NO holes
in the bottom of tanks (suction from a dip tube instead, or submerge
the pump in the tank). Every valve and fitting that's above the tank
is under zero fluid pressure when the pumps are off. That's a happy thought.
Another thought, is that someday the fluid may be drained either for shipment
or for replacement; a way to redirect pump flow to a bucket could save some
messy bailing-with-tin-cans work. That seems to be present already (the
blue-handle valve in the loc-line assembly), if I'm interpreting the pix
correctly.
