STEPPERONLINE Nema 17 Bipolar Stepper 0.9deg(400 steps/rev) 1.68A 44Ncm(62.3oz.in) Motor

Im very pleased with these. They are significantly more precise than my stock creality steppers. It seems to be more than just the 0.9 degree vs 1.8 degree step angle. Im using 1 of these for my extruder drive and a pair of the lower power 0.9 amp steppers on Z. I will be putting these 1.68amp steppers on my X and Y axes as well. If your going from 1.8 degree steppers to these, you will need to double your steps/mm which may require a firmware flash but its also may be possible to do it with g-code or from the LCD.

This is a great motor, and is silky smooth, put them on your printer and get 2x the resolution over a 1.8 stepper. Also these have a lot of torque for a 0.9 stepper, without breaking the bank!

thank you
