Need abit more info...
Was the value correct on setting the table up first time around?
If it was does the 90mm appear anywhere else in your model - say the as welded configuration?
I've only seen problems when there are configurations involved so does your weldment contain any other configurations?
Following on, does the table link show the correct configuration?
Double checking, have you checked the cutlist in the model to make sure it shows the 100mm dimension you expect?
