2) On a Fadal you would set the backlash comp afterwards by entering the measured backlash the same way: `bl,1,2,2,2` would enter 2 tenths of backlash compensation at the start, middle and end of the ballscrew. You would need to repeat this for each axis with your measured values.

It is set under the parameters, for every .500 inch of travel for each axis. I have to ask why you need to do this as I have rarely seen one that need to be set to anything other than the factory setting. If your ball screws or ball cars are worn then this would compensate.

The typical Sieg X2 mini-mill [HF 44991, Grizzly G8689, Micro-Mark & others] has a lot of backlash in the Z-axis.In my case it was .053-inches, which was almost a full turn of the fine-adjust knob. I heard that putting a shim behind the rack on the column would help by causing it to mesh tighter with the pinion gear in the head.

In those couplings there is normally a set of tapped holes next to the bolt holes, screw the bolts into the tapped holes and it should press the coupling off of the collar and free the assembly from the shaft. The split nut should be set to preload the angular contact bearings just enough that there is some noticeable drag on the ballscrew.

Typically, backlash is adjusted by tightening the feed nut retaining screw. When I tightened the feed nut retaining screw, I was only able to reduce backlash to .030″. As the one piece feed nut wears, and backlash grows, the feed nut can either be replaced (a new one costs about $36), or split into two pieces.

Also, you may want to set the backlash comp first to zero to get the total amount of backlash to make sure it is not excessive. Reading should usually be below .008. Anything above .010 you might want to consider taking a closer look. Where is the backlash coming from? Make sure the bearings are pre-loaded properly.
