It's not a backlash problem I don't think from reading the thread, its whipping of the leadscrews because he's driving them past their max speed to get the speed he wants to machine his materials i.e. beyond the capabilities/limits of his machine. Belts, R&P or ballscrews are the only solution really to machine at the speeds he wants.

Alternatively slow the feed and also RPM of the spindle until there's no whipping......
