The engine has good torque for the right power. (Rating changed to 5 stars) OLD COMMENT: Torque at 12v is not impressive. (I think it's <1 N/m because it barely performs better than the Nema 17 at 0.42 N/m) EDIT: The driver I'm using (A4988) has a single screw voltage regulator to adjust the tension raise. This greatly increased torque (and driver heat dissipation). So overall my previous comment on torque is untenable as it was a power supply/driver issue.
