FYI, the steel belts (white) can stress fracture when it does all the bending, which leads to stretching. Have you seen any issues with that? To whoever ends up with this loved machine, some new belts might be your next purchase.
I’ve used these belts on 3 different machines, MPCNC, Root2CNC and now Lowrider, in this case of the lowrider I only use it on the Y axis, because when I tested it on the X axis, it broke the parts due to the enormous tension.
I honestly never noticed any damage to the belt, are the fractures easily visible? Is it at the top or bottom?
From the tests I did, using these reinforced straps greatly reduces the vibration when well stretched.
Some videos i made in the machine using another spindle.
I haven’t used them myself, but my understanding is that the black belts are kevlar reinforced and the white ones are steel. The steel runs inside the rubber belt, and can break, so at the point(s) where it breaks, the rubber is responsible for holding the tension instead of the steel, so it flexes. The reason is that when it is bent around the pulley, it bends it, and with enough use, it will cause a stress fracture. They may also break at the bend around the zip tie.
That is just what I’ve read here in the forums. I do like the look of them, and I suspect they work really well at the beginning, but the rumor is that they do not work well after a while, because they break.
The problem is that the black are normally reinforced with fiberglass, buying with kevlar or a good branded belts like “Gates” will be a very more expensive, i would say most of lowrider users use the fiberglass version.
