Dripper Oddity
Getting the drip system started seems to be straight forward and easily repeatable.
-(assuming all hoses properly connected) Have the Return hose and the short Purple hose (see pic above) securly crimped with plastic O's.
-Have your reservoir above the Print container
-Squeeze the reservoir until dripping starts. Sometimes it quickly stops so a second short squeeze gets it going.
-Change the height of the reservoir to change the drip speed.
-The drips stop when the reservoir is empty

Now...to get the print container to drain back into the reservoir "should" be done like this:
-Lower the reservoir below the print container
-uncrimp both crimped hoses
-watch the reservoir fill
-Flow stops when the print container water level reaches the bottom of the drain hose (in the print container). The end of that hose should be the same as your print base.

Unfortunately, the return flow isn't working for me.
