x-belt problem

Hello all,

My foldarap is nearly finished, but I have a problem with the movement of the x axis when I test it. The head doesn't go to the end of the axis, never reaching the top end, and doing some loud noise for some seconds.

I've seen in the build wiki that there are some small "belt-ends" to add, to avoid the uneven tension between the middle and the sides. They are some small black parts that I can't find in my kit. Does anyone know how to get a couple of them to see if this can solve my problem?

Hello

Maybe here : [github.com]

Thank you, I hadn't seen this one.

I'm not able to print parts yet, but I see they're somewhat like the t-nuts. Do you think I could use some t-nuts in its place?
