STEPPERONLINE Nema 17 Stepper Motor Bipolar 2A 59Ncm(84oz.in) 48mm Body 4-Lead W/ 1m Cable and Connector Compatible with 3D Printer/CNC

Initially purchased one of these motors to replace the Y-Axis (Bed) Stepper as part of an Ender 3 to Voron Switchwire Conversion- figuring that a higher torque stepper would serve well.The stepperonline brand was recommended by several members of the Voron community, and I have to say, these do not disappoint.Packaging - 9.5/10. These steppers arrive to your door in tight fitting boxes filled with impact protection foam. While I would've liked to see some additional packaging around the shaft of the stepper, there is absolutely no room for the stepper to get jostled around.The datasheet card inside the box CLEARLY outlines the wire color and coil assignments in a standard, easy to read notation that makes hooking these up to any mainboard an absolute BREEZE. So refreshing.Build Quality- 9/10. Fit and finish on the exterior casing across both of the motors I've ordered has been consistently good. No rough edges, defects, or manufacturing residues were present. Motor shafts were clear of contamination, straight, and in good shape. The D-notch in the shaft is well cut.Wiring appears to be of good quality and a higher gauge than necessary given the voltage and current. Zip ties across the 1m long cable were placed consistently and held the cable together well with no obvious loose spots. I took off 1 point here because I would've liked to have seen some strain relief (or at least potting) where the wiring joins into the motor for added durability.You can leave the zip ties on, but I promptly clipped them off and wrapped the cables tightly in flame retardant automotive grade wire loom tape to extend their lifespan.Performance 10/10. Thanks to the D Shaft and a little bit of threadlocker, clamping on 20t GT2 pulleys tightly is easy.These motors have a 2A Current rating, but I run them at 75%- or 1.5A. This current coincides perfectly within the limits of a TMC2209 stepper driver, leaving you plenty of headroom on both the motor and driver so neither particularly stress each other out.In initial testing at 1.2A with a very under-tensioned Y belt, this motor produced a recommended max velocity of 250mm/s slinging an entire bed around. That's a pretty phenomenal result given the circumstances.In the 3D Printing Space, the 24V 2A architecture represents the point of maximum performance per dollar spent- and this motor is the perfect way to max out that ecosystem.

The motor works very well although the top speed is rather sluggish. The motor has excellent power for being a direct drive motor and the transition between steps is very crisp. A very delightful stepping motor to add to my shop!

Not much to say other than it worked right out of the box, zero issues. Have bought like 10 steppers from this seller and have never had a problem. Thought I’d finally leave a review incase someone else is on the fence.

Honestly a great stepper motor. I do wish it had a plug instead of being wired directly, but it's not a big deal.3D PRINTER PEOPLE PLEASE NOTE: MAKE SURE THE LENGTH IS NOT AN ISSUE. I got this for the y axis on my Vyper. It works great, but I realized too late that the bed carriage has a cutout for the motor that is too small for the 48mm body.

VERY powerful for NEMA 17. The old Nema 17 I had was a toy so, I was prepared to redesign for a Nema 23, but that was totally unnecessary. This motor is legit and could likely drive all manner of 3D printers, CNC Routers, etc. I drove this at 36 volts and 1 amp and it remained warm, not hot.DISPELLING MYTHS:WIRE COLOR IS ALWAYS MEANINGLESS (other reviewers have probably learned this by now): To determine pairs, spin the shaft. Touch two wires together spin again - if it is more difficult to spin, that is a pair. The other two are the other pair - VERY simple. It is not uncommon for motor wiring color to be MEANINGLESS. Also, if you take you motor apart, you likely ruined your motor.HEAT IS OK: I see a lot of hysteria about heat. Essentially the motors can get very hot and it is ok. If you cannot leave your finger on it for more than a second without burns - then it is too hot.CHANGING SPIN DIRECTION: Flip ANY SINGLE pair. The motor will turn in the opposite direction. If you flip both pairs it is likely nothing will change. If you swap pairs, from A to B, direction will also change - but you only need to flip a single pair to effect a change in direction.

These are solid steppers. I replaced all mine on my Millright V carve and have no complaints

Working flawlessly for over a year and thousands of print hours on my printer at 1 amp in a 70C enclosure. I wanted a bigger stepper for my Y axis to run more current at high chamber temps and avoid layer shifting and this did the job perfectly.

This motor has worked well for me. High quality, low noise with the correct driver, and high quality build. Just be sure to power this device correctly!
