UniTak3D Ender 3 Pro Belt Tensioner Kit 2020 X-axis and 2040 Profile Y-axis Upgrades for Creality Ender 3 Pro 3D Printer

The stock belt tension system led a lot to be desired. I was going to print a tensioner but wasn’t sure how well it would hold up. Plus I really wanted a cogged idle wheel for the printer. I had seen these from a post earlier and figured I’d give it a try. These work great. Took a little to get onto my printer but it has made a big difference in my print quality. If I get another printer I’ll be looking for another set for that printer.

So much better than prying with a screwdriver.

I have two of these kits installed on my printers. They are a huge upgrade over the stock belt tensioners and are aesthetically pleasing as well. I got this kit because they both match each other. Other kits have a nice X-axis tensioner and the Y-axis is a stamped steel bracket. Good job UniTak3D!

As an adjustable belt tensioner, these work exactly as they should. The fit to the machine is good and the components appear to be fairly high quality. Installation is pretty easy using the standard t-nuts. The range of adjustment is good as well, the belt can be far too loose as well as far too tight.The issue I have with this particular kit is that both the X and Y axis are limited in max travel compared to the stock Creality parts. For the X-axis, the tensioner extends towards the hot-end further than the stock tensioner does. The plate that the hot-end bolts to collides with this x-axis tensioner. This limits max travel by about 6mm compared to stock. For the Y-axis, this tensioner bolts to the top slot of the 4040 extrusion where the stock tensioner bolts to the bottom slot. This means the v-slot roller wheels collide with this y-axis tensioner. That results in a loss of max travel of about 10-12mm compared to the stock tensioner. I don't think most people would run into those limits, but I have run into situations where having those few extra millimeters would have been nice.

Something about trying to keep tension on a pulley while tightening screws never seemed right to me. And the stock pulley for the x-axis always seems to bend a little under tension. This replacement very cleverly braces itself against the plate on the back side of the bar, and the tensioner supports the pulley on both sides. It is an excellent solution. The Y-axis benefits from this arrangement as well. The only difficulty, which is true of all T-nut attachments, is in making sure the t-nuts are turned all the way before tightening them. These come complete with all the hardware, so you don't have to cannibalize the t-nuts and screws from the old tensioners.

These should be on every 3d printer. A much better way to make sure your belts are factory tight before every print. These are made very nicely out of solid machined aluminum with a nice powder coat paint job. All taps are cut nicely and the pullies are on nice smooth bearings. Easy to install on my SV01. A+

These belt tensioners fit my lk5 pro without any modification. I needed to replace the x and y belts to accommodate them, but I knew it going in and purchased the belts in the same order. A fine upgrade for the price!

The aluminum parts work really well and look nice on the printer, but they come with plastic belt pulleys that will most likely break after a few prints. Those need to be upgraded.Update: Within 10 hours of printing, the Y-axis pulley began to squeak during printing. I put oil on them before installing as well and didn’t seem to help. I took it apart and put thick grease on the tightening screw and it stops the squeaking for now.

The build quality on these is top notch. Very easy to install in a just a few minutes. A great upgrade to my Ender 3 Max printer.

Håller rätt spänning på drivremmen.

Ho acquistato le Tendicinghia Sincrono UniTak3D per l'asse X 2020 e l'asse Y 2040 della mia stampante 3D Creality, e devo dire che sono rimasto soddisfatto della loro qualità e funzionalità.Queste tendicinghie sono state utili per regolare finemente la tensione delle cinghie sull'asse X e Y della mia stampante, consentendomi di ottenere una maggiore precisione nei movimenti e una migliore qualità di stampa.Una caratteristica che mi ha particolarmente colpito è stata la facilità di installazione e regolazione delle cinghie. Le istruzioni fornite erano chiare e facili da seguire, e ho apprezzato il fatto che il kit includeva tutti gli strumenti necessari per l'installazione.Un suggerimento che vorrei condividere è quello di allentare leggermente le cinghie quando si lascia la stampante a riposo per lungo tempo, in modo da evitare tensioni eccessive che potrebbero danneggiare i componenti nel tempo.In conclusione, le Tendicinghia Sincrono UniTak3D sono un ottimo accessorio per la stampante 3D Creality, che consiglio vivamente a chiunque cerchi un miglioramento nella precisione e nella qualità di stampa della propria stampante.

Belle qualité. Très content de mon achat.

Passt einwandfrei Ender 3S1 plus ob man das braucht ? Mit dem Orginal teilen funktioniert es auch. Ist halt Luxus
