john your a star
i altered the decay mode to 100% and it made a vast improvement but it still wasn't right. i then went in to mach 3 and altered the active high verses active low setting and that worked a treat.
i went back to the decay mode and tried all the different settings but the best was the 100% setting.
i am busy with other stuff over the next day or two but as soon as i get a chance i will try it by cutting a job.
will this have an effect on the distance travel or will that side of things remain the same.

thank you for your help so far
