Hi All on my home made Cnc plasma I have a part with multiple holes and they are not in the correct places ..... what could be the problem? .... it’s like it shifted to the side, my steps per is correct.. I’m using mach3 and sheetcam, what’s strange is when I have this specific part cut it causes this problem, I was told I am loosing steps on nema 23 stepper motors or emi , but emi only effects the system before the torch fires and if I’m loosing steps how is this happening? ... iv attachet pix of the drawing and part, if you look closely it looks like the center geometry has shifted to the right.
