Topic: Is Nema 17 1A 3.5V too weak as extruder motor for 3d printing?

This motor https://www.omc-stepperonline.com/nema- … 1004s.html is being sold by a online sale website so I was wondering if it's worth it.
Besides, what range of amperage and holding torque should we look for when buying stepper motors? These days stepper motors seem to be the norm with 3d printers, especially nema 17.
Thanks.

Should be fine when paired with a titan. if going direct drive the other one you posted would likely be a better choice. And inho have them ship from your local warehouse. a couple bucks more but easier returns id needed.

I think it is a weak step motor, only 13Ncm (Meets the low end of the required spec though), I usually use step motor with >45Ncm (about $1-$2 more expensive than the 13Ncm one but lot heavier). The 13Ncm step motor is designed for situations when the weight or the size of the step motor really matters but don't need strong holding torque.
