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
Are you referring to cm or mm? when you say you ask for 25 and get 22 is it only the same part of your belt drive you get this error or is the error seen no matter where you do the move?
I'll get it finished sometime after I start it.....
