Hi, I changed over to the Openbuild GT3 Belts a little while ago when i also changed to Nema 23 Steppers. I’ve found the belts to be a little unreliable. I get 2 months roughly out of a belt before it breaks. I didn’t have this with the GT2 which came with my X carve. I’m not sure if this is me over tensioning the belts or a poor quality belt. > **[Extrusion & Mechanics](https://ooznest.co.uk/product-category/extrusion-mechanics/)** Ooznest is the UK distributor for Openbuilds. Is there a higher quality GT3 belt on the market? I’ve looked but haven’t found anything. ---

You went to a GT3 pulley before running the GT3 belts? ---

I bought the pulleys and belt as a kit from openbuilds along with the steppers. The belts seam to mesh nicely with the pulleys. I thought I’d over tighten the belt ---

Have you solved this issue ? I had the same thing happening. All parts from openbuilds. Went with the 9mm belts and all had been good. ---

Ya. I still call it an x-carve but there’s not really much left of the original lol. I just finally got your waste board finished up and I think I’m done for a while. ---

I’ve gone for a screw drive set up. Just working on rebuilding the machine today. The GT3 belts from openbuilds just didn’t preform for me.
