I have the set up as shown in the picture below, The stepper Motor is supposed to drive the water Container Up and Down , stirring the solution in the container. My stepper Motor is a Nema 17 and I'm using a TB6600 driver for micro-stepping.
I don't know if my motor holding torque is too small, or the gear set up is not done properly, because the motor is struggling to drive the container up and down when 400mL of water is thrown is the container. Can someone help me with calculation for the right Torque to carry this load. The Overall load is about 600g.
