1/ When received, the tables were loose. This had a noticeable negative effect on the Z axis. When you secured the two lever screws to fix the head at a desired height, the DRO shows an erratic variation reaching 25/100 mm (!!) of the Z value. This was completely solved by tightening the screws holding the Z gib. So I advise to tighten the gibs screws as needed to relieve any play.
2/ The handwheel of the Z axis is quite difficult to manipulate, as the counterpoise balances only partly the weight of the head. I replaced it by a 15 cm handwheel (EBay) and an adapter made on my lathe. Incredibly more comfortable and making FAR easy to reach the desired Z value.
3/ On delivery the spindle had a runout completely out of specs . (mill replaced by the distributor). Check against the specs sheets!.
