Search the forums, steel core belts are far more likely to cause problems than to solve them. The problem is that they get flexed too far and the steel fibers break, causing them to go noodly and cause trouble.
Very highly recommended to replace them with fiber reinforced belts asap.
They last about 8 months of light use. Agreed they aren’t a permanent solution.
I’m selling this anyway.
We have done troubleshooting where they last about 8mins. The fiberglass ones work great. But YMMV.
Absolutely true. I think my main problem was that the kit came with just 3 inches too short for the belts.
I’m just repeating what I learned from NYC CNC shapeoko feeds and speeds video mentioning steel belts.
