Hi and a Happy New Year to all!

So I've been reading on a couple of resent threads about some UM2 having the issue of spacers/bearings being slightly out of align and causing belts to grind? I'd never heard of that before but looking at my machine, I've noticed some black specks on my stepper motor case as above (I always assumed it was normal dust?), but it may be this grinding belt issue?.

I havent noticed any effect in print quality but just wondering if:

1. Is it something that I should fix?

2. How can it be fixed?

3. What causes it?

Over to you guys.

Cheers

Franc

    Hi,

    I have the same and I guess this just happens. I wouldn't worry about it, the short belts are not that narrow, the won't break any time soon :)

    That's a double post of this, isn't it?

     

    It is - i was doubling my chances of getting some feedback!

    I understand the problem and that its not too critical, but i'm still not exactly sure how to fix it?

    I do some more research

    cheers
