thanks for bringing this up the topic has been updated

A little tip for those who have one or two bad pulleys.

While I was waiting for my new pulleys I made a small change in the bad ones.

I drilled a 2.5mm hole next to the belt and tapped with an M3.
With this you get a lot more material for the set screw.

Got the new pulleys and it seems to be same as I already Have.

So, either I will order other on ebay or fix the other I already did with 2 of them.
The problem is the drive pulley ( the pulley where the motor belt and other belt are on).

Strange that velleman didn’t could get better pulleys.
