Syringe pump mechanism + electronics

 

This is the stepper motor driver design we are hoping to use to control a syringe. Here is the PDF describing the assembly: etapes fab venti v2

And here is the github repo:

This is the syringe pumping prototype I developed. It uses 8020, a NEMA stepper with built in threaded rod, NEMA motor brackets, and linear bearings. The rest is 3D printed and uses M3 and M4 screws.
