Absolutly perfect
The item looks good as described, the lead screw nice, straight as an arrow. I do not want mess with backlash, therefore I was exchanged the brass nut with better nut, without backlash issue ( I was ordered before from “Banggood” SKU490735-49EO0 2mm ). Unfortunately no one sell the bracket for this brass nut.
I ordered a replacement leadscrew because I thought it would be bend due to shipping. This was not the case, it was super straight and it moves super smooth. Happy customer!
Ware entspricht genau der Beschreibung. Klasse Produkt zum fairen Preis. Ansteuerungskabel in ausreichender Länge.

I bought this for my hypercube 3d printer build which is still in progress. the stepper looks ok, but i've not run it yet, has 6p connector and comes with lead 6p to 4p to fit ramps 1.4 etc driver. the lead screw has apox 300mm of usable length, has 1 start and 1 rev is aprox 2mm travel. the Tnut supplied is a good fit, but is causing me some problems , as the tube outer is 12,7mm, and the flange comes with 3 equaly spaced m3 holes, where as the bracket I have to fit the Tnut to has a 10mm opening and 4x 3mm holes equally spaced. I have managed to open the 10mm to accept the 12.7mm tube, but the fixing screws are still a problem. as a FYI, I also bought the 300mm lead screw that needs a flexible coupling, the T nut that comes with this is correct for my Tnut mount, but the screw is 4 start, thus 1 rev moves 8mm so the Tnuts are NOT interchangable 8-( so at the end of the day I'm going to use the stepper with lead screw & when its working a new Tnut mount will be one of my 1st prints.
