BP Series1 CNC Maintenance manual

The head still needs a metering unit of some kind, although on my shizouka the metering unit is on the head itself.
Even if the pipe up to the head was to syphon back, air quickly passes through the metering units.

Yes, the head has meters - Quill, Z ballscrew and back gear slide.
All these are fed from an FJB-0/3 on the first manifold. It is this that I thought strange, why not use a higher flow meter here, or at least one that can pass the same amount of lube as the 3 it preceeds combined.

I have ordered some spares of each rate so I can experiment a little, the feed tubes I'm using are transparent so I can see the lube as it flows through the system.
