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 ...

So in the X parameters screen, there is a setting for X backlash. A similar setting is available in the other axis. The actual amount of the adjustment would be in encoder counts. If you look farther up the screen, you might see something like "X Ratio steps/unit = 138718" Do not change this!.

These Chinese mills come with antibacklash ball nuts which are pretty crappy quality but they do work when the machine is new. I bought a Chinese router and one problem I found was the z ball screw was relying on the coupler and not the bottom bearing to secure it from moving.

I was thinking of the backlash issue too, b/c I have ballscrews on a new CNC mill in the basement and it's soooo much nicer than trapezoid screws for the purpose: lots of backandforth motion.

The cost of edge drive is low, but the pinion needs to be replaced every 25 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

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.

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.
