hello, i'm kind of new to this machinning with cnc.
i recently converted my grizzle 8086 mill to cnc using hass plans, using a c11 driver and stepper motors.
i have cut a few simpple things with good results, they were basicly straight cuts in both x and y direction. did 2 text cuts as well that had some curved lines.
i am using solid works cad with the HSMXpress for poast code.
i loaded the code cut the part and it came out the correct demintion in the general x axis direction. and as it got close to the max y direction things stoped moving???
i'm cutting a 5/8 hole. in the x direction it measures 0.624 aproxamatly but yis 0.598 aprox. see the pic.
any idea on what is happening???
