Recall Will did try and measure stretch in this post > [@Ongoing Dimensional Accuracy (DA)/Measuring Belt Stretch](https://forums.maslowcnc.com/t/ongoing-dimensional-accuracy-da-measuring-belt-stretch/23337): > > This is somewhat of a continuation of [x and y off by 1%](https://forums.maslowcnc.com/t/x-and-y-off-by-1/23002/111). There, I realized I was cutting parallelograms–say I programmed two adjacent 100mm squares. When I cut them and hold them on top of each other, they line up well, but when I rotate 1 90°, the lack of orthagonality becomes apparent. I happened upon these realities when I began attempting to cut a peg board. I made holes in a cross shape so the board could be used both horizontally or vertically, but the widths of the two cuts across the bo… Dano --- _[View the full topic](https://forums.maslowcnc.com/t/x-y-accuracy-analysis/23816)._
