Normally the backlash direction can be selected, and when a reverse in direction occurs, there is normally a rapid move of the servo to take up the set backlash only, IOW the motor shaft only should move, the axis itself should not jump, if it does, it is usually a sign that the backlash amount is too large, try it back to zero and see how much movement of the shaft occurs before the axis ...

The CNC conversion using ball screws will remove all of the backlash at that point. I think your choice of CNC conversion hardware is good. This will be a fun (and at times a frustrating) project. If you want to use it as a manual/CNC machine, then building some kind of motor decoupling system would be a good idea.

This preloading method ensures 4 points of contact between the ball screw grooves and nut. This is accomplished by inserting slightly oversized steel balls. This preload is applied by machining the nut with a groove offset at the center in the amount of desired preload. A preloading method using a spacer between a set of nuts to achieve the ...

On a new mill, this value measured should be less than " on the Zaxis and less than .0013" on X and Yaxis. Tighten the gib by one turn by loosening the lower screw first, then tightening the upper screw. Measure the backlash again. Repeat this procedure until the measured backlash begins to increase.

The minmum clearance is about for most purposes. Many machine tool have adjustable backlash features allowing " or even less. As the screw wears it gets smaller in PD usually near the center where most of the wear takes place. This limits the adjustment if the screw is to be used over its full range.

A sure way of telling if you need to set the backlash in X or Y is to mill bore a large hole then run an indicator around the hole paying special attention to the four quadrants. If the indicator jumps .001 or more in the quadrants you may be way overdue for a backlash resetting. Fadals have backlash setting for center, left, and right ends of ...

The design of the backlash compensation nut sucks. It is a low end machine. The only real reason to have a backlash elimination mechanism is for larger mills where you want to climb mill and not have the cutter hog into the work. Think Kerney Trecker or Cincinnati or Brown and Sharpe mill here. My Deckel has a nut that is about 3" long.
