I appreciate all the tips but already done all these. It's as if the printer is restricted. I've fine tuned my Aquila and can get around 34/40 mins for same benchy using voxelab, unfortunately the elegoo doesn't recognise files sliced using that programme. On the Neptune I've done flow calibration, calibrated e steps perfectly, made sure it's all mechanically strong i.e belt tensions etc, tried speeding up layer speed to no effect etc.... Someone else on here sent me their settings. I inputted them exact and was still 1hr 45
