> 24 hourI bought an Anycubic Chiron and was stunned that it does not have axis tensioners on the belts. My X axis out of the box was so loose that it would not even hold steps at all. I broke the zip ties and closed the belt one tooth length, and that helped but still wasn’t enough, there was a lot of backlash in the X axis moves. Then, went another tooth and while that was a lot better still, it wasn’t right. Then I bought and installed this tensioner and it bolted right up the the Chiron. The only modification I had to do is the Chiron uses one of the bolts from the old pulley wheel mount as it’s X-axis homing stop, and this does not accommodate for that. I originally tried just putting in a longer bolt so that it would still work almost as factory, but the bolt was too far left from where the factory X home stop is and so the carriage hit the upright before hitting the stop. So to get the homing stop location back you need to add another bolt to the aluminum extrusion next to this tensioner but that is easy to do.

> 24 hourThis has made getting the belt on my Ender 3 super easy and fast. For my ender 3 I did not have to re use any of the standard hardware which many people said they had to. I did not and I did not have to take the belt off to install this... I did have to take apart the entire part but it is straight forward and easy to understand.

> 24 hourWas impressed with the quality and strength of the construction. I was happy to find out that I didnt even have to change the length of my belts. They are far superior to the acrylic parts that came with my printer

> 24 hourMuch easier to tension the belt but the hole through the sheave is not bored true making the sheave wobble as it turns. Looks great but this little issue is disappointing.

> 24 hourThis worked quite nicely in my CR-10. Its great being able to just turn a knob instead of pull on something and tighten bolts. If you know, you know.

> 24 hourA great choice for anyone who wants to replace the original Belt Stretch Straighten Tensioner on the Ender 3D printer.

> 24 hourMakes it much easier to properly tension the belt for the Ender 3 Y axis. You should also get the adjuster for the X axis as well.

> 24 hourAfter fussing with the original bracket on my cr-10s for about an hour, I decided to get this and had it installed and adjusted within 15 minutes. Worked!
