accuracy

What kind of accuracy you guys get from this? i did 50mm circle and it turned 50.2mm on one spot and the opposite side it was 50.45mm so not even circle. need to took it apart this weekend and see what is twisting the x axis pipe.probably z-axis is bending the x-axis.

post your best results and guys be honest:)

As a plotter, or milling? I have never tested anything other than my 3d prints and they come out as good as any of my other printers.

if you cut 50mm circle in wood for example do you get exactly 50mm?
