Make sure this is set to angular, see pic.
Also you will likely want the 360 rollover but depends on how you will work.

That is checked so I'm not sure what is going on has to be something wacky with the motor I tried 35.55 in steps it almost seemed that
this was closer that the other numbers I tried. God bless you for all your help and patience !

If you attach your xml I will take a look and see if there is an issue with it.
Are you sure your belt drive is 40:1 reduction as that seems quite a lot for a single belt reduction, would mean your driven pulley would have to have 40 times more teeth than the driver pulley.

So that would mean if your driver pulley had 10 teeth your driven had 400? Seems a lot.

No the main pulley has 40 and the small pulley has  10 and the belt is 40 teeth

Ah ok so 4:1 reduction that means the 35.55555 is the correct number :)

I'm going to work more with this tomorrow . I truly appreciate you help so tomorrow I will use the 35.555 when I used this number it seemed that the rotation was rather slow.
