does it have to be special type of wire? thick, thin ect? or anyone else with any ideas please!!

ok i tried the grounding wire from a screw on the base of the cutter to a screw on the stand. The whole thing is standing on wooden flooring, but the problem still occurs! Anymore suggestions please?

Can anyone help with this grounding buisiness? or any other solution please?

Thanks for reply, but how do i install a ground wire?...I

As mentioned above I have a relatively new Seiki SK-870T. I use "ArtCut" to cut my vinyl and have until now never really had any dramatic problems. However I tried cutting a vector which was 30cm wide and 150cm long, this cut fine untill after about 60 cm of the vinyl was cut, than the vinyl suddenly started to roll back to the start point, and the blade started heading towards the far left of the machine, cutting a nice long diagnal line on the way and then just stopped, leaving my half plotted vector with a diagnal cut through it :-( I tried the same vector again in smaller size and cut no problems. I tried a different vector in small and again no problems, untill i tried the second vector on a larger scale (again approx 1 meter long) than the problem re-occured, again after approx. 55-60 cm. Anyone else had this problem or know of a solution? Many thanks in advance :-)
