Last night I performed the PID autotune on the nozzle, not sure if it made any difference but I wiggled the Z bed around a bit and the layer issue has seemed to minimise a bit. But maybe it had something to do with the model. The 3DBenchy bridging section failed near the top so I increased the travel speed to 95mm/s and did a bridge model test. But I am impressed the printer is now able to create the front hull without any drooping.

Also, if you are giving away ABS filament... I will gladly be willing to help you out . I am located in Australia though, so i'm not sure how much shipping will cost me.
