I sent my servo dynamics drive control to Parts and Smarts. Al tuned it but I still have the .0156" axis lag at standstill. I talked to Al and he thinks there may be a ground issue. I tried adjusting the balance but it takes 5 turns to drop it to .0143" All axis have this same lag machine will run a program with straight moves but won't run a circle mill or an arc asterisks are not lit. If I E-stop and reset asterisks will light then axis will jump to the .0156"
