Iverntech NEMA 17 Stepper Motor with Integrated Tr8x2 2mm Lead 310mm T8 Lead Screw for 3D Printers Z Axis or CNC Machine

So I bought this stepper motor to replace the one in my Anycubic Photon Mono 6X Ks after one of the bearings decided to seize after getting resin in it somehow. My guess is some resin splashed on the screw and ran down into the motor. What should have been a quick(ish) swap out turned out to be anything but. The motor started having seizures as soon as I attempted to set the Z height. It just juttered and then would go neither up or down - just buzz, stuck between up and down actions. Turns out, even though the connectors and the wiring harnesses are the same, the circuit boards are different. Ugghh... So rather than return it and try to get one from Anycubic - which takes forever, I disassembled both and used the top and bottom bearing carriers from the new one on the old stepper motor. The bearings on the new one are bigger, so it should last for quite some time. I say it's just okay because it wasn't a simple straightforward swap, and I only ended up using the bearing carriers from it. It may be a different experience for you and your needs. Meh. Either way I got it to do what I needed.

It's a bit early to tell yes but it appears to work flawlessly with the Phrozen sonic mighty 4k. You can actually use the existing cables with little to no issue, the cable in the machine does show the CORRECT configuration of wire layout so if you want to be safe you will need to redo the included wire. I bought the model with the plastic guide but and found that it didn't fit the print bed but the existing guide from the sonic mighty is compatible with the guide rod for this motor. It is slightly smaller then the motor that comes with the sonic mighty however. So far a good purchase. Update: so a few days ago I had a power outage that knocked the motor out of action. Fortunately I managed to revive it, but yeah it's worked flawlessly till a few days ago.

Bought for my 3D printer. Made noise and would not move from the moment it was installed. Maybe it was an isolated instance.

The stepper motor is fine, but plan on getting a different nut (other than the black plastic one that came with mine), or waste half of your motor's energy on friction.
