6mm and thicker than the original.
after replacing it I used 2lbs per inch tension.
the belt was riding in the middle of the drive pulley.
Looked good. Then after a wile into a job the belt moved to the side away from the motor close to the edge.
No matter what that always happens to my belts on all of them No amount of adjustment or anything will fix this.
Hopefully I can run this job and get it done before another belt breaking. Then I am going to hang my hat on this. I will have to either wait for some cash to upgrade to the ball screw or just sell everything and move on to something else. I can’t make money if the system will not stay functioning…
