Well Gentlemen,
I need to come back to the well and ask a question with regard to my Bridgeport Interact 412. I have taken the X Axis servo out, had it bench tested and taken apart, an then remounted it. I am getting the same problem I had before, however, not as bad.
The problem is that the axis is jogging or hunting back and forth when homing or running. Before I removed the servo, it would not home in the X, and I couldn't go any further. After the re-mounting, I can sometimes skip beyond the X axis homing function and start running a program. When the program runs, when a move is called in the X axis, again, it will job vigorously left and right. It still looks like the program is running normally, but obviously, the X Axis is going Balistic. I'm getting feedback for the Axis, at the control on the screen, however, it almost acts like its lost postition and is trying to find it. I swapped x and y cables just to be on the safe side with the cables and it stayed with the servo. It seems to me I was reading somewhere here, that there is some screw that may need adjusting, inside the servo motor. Like a tuning screw or something. Does anyone have any idea, if this is the case. Maybe I'm all wet on this, but I'm scratching my head on this one. If you don't understand what I'm reffering to, I can see about posting some video of what the axis is doing.
Thanks for the help.

PS- It has a Heidenhain 155 control.
