4pcs Nema 17 Stepper Motor Bipolar 2A 59Ncm (84oz.in) 48mm Length for 3D Printer/CNC Machine/Robotics

I ordered these along with TB6600 drivers and a power supply. No issues and they are running well. I am building a small cnc machine using an Arduino Mega.

Currently using with a CNC with TB6600 stepper drivers. Work great. Running at 2 amps.

Bueeeeno

I don't know how "Sheerness" relates to a stepper motor, but these seem like good value for the money. I connected then to my duet 2 wifi via a signal splitter and they functioned without any tinkering, but note these are too tall/long for a cr-10 z axis without modification to the printer. They were very quiet and moved smoothly. I only buy nema 17's with integrated cables now because the failure is almost always the 6-pin JST-XH connector or the accompanying itsy-bitsy crimp terminals. Happy CNCing.

Compared to OMC these seem to have 1/2 or less torque at equal current. At low speed movements they vibrate badly. They caused bad ripples on the outer perimeter of my 3d prints. I had to replace them with motors from a different manufacturer. All four motors from the batch exhibit this behavior.

Good working motors, not much else to say

I should have looked at the comments first. These are not 2 Amp motors. Anything above 1.5A stalls them. Very disappointed. I'll be returning them.
