I have a ST30 lathe and I've recently jumped up the lubrication pumps on the machine to get more oil flowing to the spindle bearings.
This worked and I saw that the lube oil level go down and the pumps seem to be sending more oil.
This morning, I noticed that it doesn't seem to send as much. Only a drop or two, and not the multiples I was seeing before.

There doesn't seem to be any air in the lines or leaks.
I really don't want the spindle damaged from lack of oil
Ideas?

You sure that the lub is for the spindle, not the slideways
Bearings are fiddly things, too much lub can be as catastropic as to little.
Low speed lathe bearings can be the grease sealed type. Sealed to keep coolant out of them.
Slideway lub is a medium viscosity, say ISO46 to ISO68. It needs the thicker grade for greater stickiness on more worn slides.
Spindles that need oil, need a very thin oil, nearly a fine mist injected with air. It tends to flush any particles out of the bearing race.
Too much effort in rolling a ball thru a lot of oil/grease creates heat.... heat is #1 killer of bearings

Thanks!
Yeah, it's for the spindle.
Seems to be operating to specs in the manual now. I adjusted a parameter.
