I finally got a smooth stepper for my mill after 7 years. Finally got the axis working thanks to John's help over New Years weekend! I have no control of my spindle now. I spent the whole weekend messing around with settings and only managed to get the spindle to either go 100 RPM or 4000 Rpm. Does anyone that has a smooth stepper (ethernet) on their Novakon have any tricks or tip for settings? Also, I still have the momentary stop of movement from line to line as I was hoping to do away with by upgrading to the ESS.
