Printer is a V-core 3.1 400m. Orbiter 2 with phaetus rapido UHF 0.6mm nozzle. Filament is hatchbox PLA, Speed is mostly 150mm/s. I have checked the equivalent to e steps, so the printer is pushing 100mm of filament if told to extrude 100mm. I am still getting underextrusion at a EM of 1.2 and seems to vary between prusa and super slicer with identical settings as far as i can tell. Below are photos of different test prints with settings, I'll put them in replies so that they are better organized. Nozzle diameter is set as 0.6mm in slicer and printer.cfg, extrusion width is set so that both slicers will calculate it on their own base on nozzle diameter
