Just halted a 2 1/2 hr prime blend run at 430x9 at 1:1 mem (1720) - might be getting somewhere at last. Thanks to MnM and EF for posting detailed settings - I am using a hybrid of both so far. Just dialled in 450 so we'll see how far this gets. On AIR with stock heatpipe assy bar AS5 and washers so we'll see what happens ...............
