Review on Enhance Print Quality with BIGTREETECH Direct Vibration Creality Printers by Kenneth Witte

So I got these for my Ender 3 Pro and I haven't checked if it has removable pulleys or not, it doesn't. I decided to install them anyway and see what happened. First of all, it is very easy to install, although there are no instructions, it was enough to watch a video on YouTube to quickly install it on the car, but due to the impossibility of moving the pulley, the rope is pre-tensioned on one side of the beam , but it will still work. It's the same problem for the x and y axis, and for the y axis I had to remove half of the small guide cylinder to get it to fit and move properly. In the end, both were more or less established. The only problem with this is that the Y-axis stop switch is harder for the machine to press, while the motor can push the bed against the stop, making the vibration loud at times. The motor will crash into the bed dial, but it will still work magically. I suspect this could become an issue with larger prints that press the bed against the motor more often. It works quite well, despite the shoddy operation, the machine is still able to perform with similar precision as if those tumors weren't attached to it. . I tested it with some measuring cubes and a few rounds to check the rope tension, the result is still pretty good. To be honest the noise dampening with this machine is God sent, its loud screeching and the groan of its engines are much quieter in the same room and I suspect it will be little or not at all audible in a closet or room, though his fans are still loud. So if you have an Ender 3 Pro that doesn't have a detachable pulley and you don't mind potentially limiting the life of your rope to extend yours, they work quite well.
