I am trying to make an autocutter to cut the red tubing in the attached photo CAM.jpg
I have a NEMA 17 stepper motor which can provide 0.4Nm
And this needs to turn the cam also in the photo and push a stanley knife blade down with enough force to slice through the red tubing.
However it seems that 0.4nM is no where near enough.
But I don't have any context, through previous projects, to give much idea of the ball park amount of torque I would need.
Looking on ebay at various NEMA stepper motors I found this table attachment NEMA.jpg
Can anyone give me at least a rough idea of the minimum torque (from NEMA.jpg) I am likely to need to cut through the plastic tubing?
