Oil not going to the Z column or Z ballscrew? Try this small Fix

I wrote a PDF time ago about this small fix that I have implemented on the 1100M in order to overcome the problem when oil start to fall by gravity down the Z line and never reach the Z column or Z ballscrew.

Yes… you can add a second pump if necesary but apliing this fix will solve your oil problems without a second pump or several manual pump strokes that will end dropping oil over the XY carriage.
