I finally got my PCB mill all wired up and I started with the stepconf configuration that works with my X2 mill. Neither the X axis or the Z axis work. They just shudder. However, the Y axis works fine it will do 180 ipm. So I took the stepper off of the X axis to see if it would turn by itself and it would not. It just shuddered. So I took the motor off the Y axis and put it on the X to see if it would work and no joy. It just shuddered. So just to check things out I put the motor from the X axis on the Y axis and guess what it worked fine.
All three axis are using 5 tpi ball screws and linear rails. When I turn the X axis screw by itself it seems to move freely enough. The stepper motors are from Automation Direct and are 425oz/in motors so they should have enough power. I am using new/old Superior stepper drivers but they drive the X2 mill just fine. Any suggestions in where to go from here?
