I bought this stepper motor and followed the HackaDay guide to replace my stepper motor. My original one was slightly bent and was causing z banding. As it shows in the video, when I try to tell the printer to raise or lower on the Z axis, it just makes a thunk-like noise and barely moves. The video shows me using the controls to move the motor three time (twice “up”, once “down”). I have also tried just sending g code with Ponterface.
I unfortunately didn’t test out the motor before cutting it down to size and installing it, but does this look like a bad motor or have I messed up something? I hooked up the original motor and it spins just fine.

Last I checked, robotdigg had them. Just looked again, don't see any immediately.
Pusa mk3 sure has some nice 4-start integral leadscrews, maybe you can order some from prusa at a markup?
Edit-
No word on quality, but there's plenty on Amazon, fwiw.

Double edit- I didn't read as well as I should have, apologies.
Any of these should work. You'll have to.cut the lead screw of course. Well actually there is a Z-axis extension mod or two that you may want to look into before cutting the lead screw.
Also be sure to check the shipping dates since it may ship from overseas.
