Great job!!
May I ask how much ml is the syringe? and could you please provide the Motor torque info? I have made something similar using a belt instead of the screw rod but my Nema17 has only like 12 n.cm which almost done the job but not really efficient.

How I can calculate the step rate (steps/second) for a given flow rate(ml/second)?

Hello thank you for this brilliant video. I wanted to use this with a 50ml syringe so would need to make some changes on the 3d print file. Do you have the step file for this? Thank you so much!

Seria un buen proyecto implementarlo para la administración de medicamentos, costaría menos que los equipos actualmente disponibles.
