Can't get carriage belt to have proper tension

I can’t get this to have the proper tension. I already pressing on the roller/pullet with my finger towards the right while screwing the allen bolt and when I move the carriage with my hand I can see the left roller/pulley making the belt “jump” every 1-3 inches or so… like its not engaging properly. I ran a few tests cutting a little circle then an outer circle (both centered from each other) and the results are so OFF. They are not centered at all. Any tips?

Have you inspected your carriage plate wheels? One of them may be cracked.

They seem to be fine once I removed it

Can be closed. This one already resolved in another post as well.

I see you already posted another post about this and we’re working on it there, so I’m going to close this topic.
