iam thinking you aint settin it it up right!!!!
i HAD A PNC-1000, and i cut from COREL.............and i had it set for 19.50 x 62.99!!!!
YOU........need to set MEDIA SIZE in the ROLAND DRIVER, and also SET PAGE SIZE in corel.........TO BE THE SAME SIZES.
as for the length, its a DEFAULT SETTING on that plotter. you can do longer stuff, but need a SIGN-CAD program that can PANEL. BUT, with that plotter, i wouldnt recommend increasing the length past 62.99, as its not known for its tracking.
you can, if your smart, learn to cut in that 62.99 window, you can PANEL each one.
