Cutter is over shooting measurments HELP!!

[killerdecals 0]

Ok I have the Refine MH1351 cutter and it has worked pretty good thus far. What is happening is I am trying to cut a phone number 12" high by 90" long on 15" vinyl. I line the cutter up to it's start position and when I go to cut it starts it's prefeed as normal but instead of stopping at 12" it just keeps going until it hits the otherside of the machine. It works fine with shorter lengths but longer stuff it has troubles. So why during prefeed on longer lengths does it not stop where it should? No I do not have the X and Y measurments backwards either. Thanks I use sign blazer
