it is all relative to the machine, nozzle and the material.. it is a science experiment. There is a setting for filament diameter which should be measured and average actual size input to the slicer.. I have a very different machine than you do, most filaments need 92-93 with mine.. so do what works best for you. I think in one slicer the default filament size is not 1.75 so you may want to make sure that is set right.. good luck
