I have spent some time attempting to setup my AL960b. I have it leveled and dial indicator reading 0 along a ~250mm test bar from the tool post. The test bar appears to sag 0.03mm along its length when measuring on the top of the bar (the bar is MT5 solid - some sag might be expected?).
Performing the collar turning test with a 45mm piece of AL (in a 3 jaw with no tail stock support), I am seeing .000mm at the tail stock, .000 at the headstock. BUT, -0.007mm in the middle. What on earth could be causing it to cut concave?
