I've being using this motors in a Prusa 3d printer (Z axis). Great quality ¡¡¡
Better design than using a coupler to attach leadscrew to stepper. Easily the best price of all sellers. Only downside is that the motor model doesn't have a high holding torque rating, half of what nema17 can put out.
Not packed very well packed (just some foam in a black mailing bag) but arrived with no damage at all. The stepping angle isn't listed here but it's a TR8 4MM stepping angle (you may need to change your steps per mm if changing in your printer). The supplied are bigger (hole spacing) than most others used on printers so I bought these ones: https://www.banggood.com/T8-Anti-Backlash-Spring-Loaded-Nut-For-4mm-Acme-Threaded-Rod-Lead-Screws-3D-Printer-Accessories-p-1140252.html
Motor arrived in perfect condition and the screw is straight. I was looking for the right stepper for my Prusa MK2 upgrade project. Nut have a little backlash. Nut dimensions is bigger than on standart printers!
item is perfect and the screw is straight, by chance. however the packaging was in theory not good enough since it was soft wrap. A rigid cardboard package would be preferred for this item
The product arrived VERY fast and in good shape, but it was not packed very well. For something that needs an extremely accurate piece (the lead screw), it should have been better protected than just wrapped in foam, especially for a trip from China to the US. Luckily, it arrive without damage and works perfectly.
No issues. Works just fine
Muy buen usillo, pero el motor tiene muy poca fuerza para una p3steel y se para a la minima
it is not straight :(
Good motor
