Hi all, I’m from Italy. I’ve got an OX 1000x1500mm since about two years. First thing I’ve changed is the belt clamping system, I don’t really like to have a t-nut with a screw pulling on the belt, so I’ve made a new system fixed to the machine frame. I’ve done several works, most of them are vinyl clocks, but since about one month I’ve seen a bad error when the machine is cutting (see attached picture). It seems that motors are losing steps but, I’ve tried to mount a drag bit with a ruler on the work table, and the motors movements are correct. I don’t really know how to figure out what is causing that problem.
If I made a circle, it didn’t come round at all but if I made a square it comes out perfect!
