Ever since we got the machine, the cutting accuracy has been less than desirable. It seems the machine is off in the X-axis direction. For example, if we print a 1x3 rectangle, it will cut the 1" sides dead on(y-axis), but the length (x-axis) off by a mm or two. We are kinda getting fed up with it and would like to know if this is normal or if there are any corrections we can put into the machine to allow it to be dead on anyway it cuts. Thanks.
