CSMIO, servo motors and drives arrived a minute ago, all looks very heavy-duty indeed, just ordered a DB25 break-out block for the MPG unit and one of the neat little power divider blocks from CS-Labs :)

Got the mill head stripped, paint on order, removed all the surplus gears and junk from the head.

Wondering about doing the neat Z axis fit where the ball-screw takes the place of the feed-stop screw and is a 1605 unit OR doing the more common fit where the ball-screw sits in front of the original feed-stop screw position???

The only downside I see with the first option is that the pulley sits at the bottom of the screw right in front of the spindle nose.
