This is a remix of the peristaltic planetary gear with lots of improvements baked in. Most notably, this pump mounts directly onto a NEMA 17 stepper motor. It also opens up using a hinge to allow the tubing to be easily loaded into the pump.
NOTE: This pump is mostly functional, but has one fatal flaw. For some reason operating this pump causes the tubing to "walk" or "feed" into the pump, causing the tubing on one side of the pump to shorten. I have tried several things (including tube clamps, and hose adaptors to hold onto the tube) in an attempt to get this fixed, but without much success. Any ideas much appreciated!
