Hi,

Was wondering is anyone has had a similar problem, I'm trying to help my brother with his cnc machine. its using a ball screw on the z and belts on the x and y, 1 motor on x & z and 2 on the y nema23's . Y and Z seems to work fine. When I move X 300cm in Mach3 it moves 300 but when I move it say 25 it only moves to 22. The annoying thing is when I move it 25 x 12 it lands on 300 again, its breaking my brain
