Nice, i have been thinking of something like this but dismissed it because id be afraid of over doing it on the lube and flooding it. If overflowing isn’t good for your vehicle, it can’t be good for a cnc either.
Now I have to do some unrelated routine maintenance on my machine
Going to go manual pump in the beginning. I agree that a scheduled delivery by an automatic system may be overkill, but on the other hand. One pump and your done sounds pretty good.
