Yes I did calibrate the extruder and then the X , Y and Z axis. My 20mm cubes where coming out great. My last step was calibrating flow with .8mm walls.
I will look into horizontal expansion sound promising, would this allow me to leave the flow at lets say 100% while compensating a minus amount to reduce the size of the walls? I'll go research that option if it works as I hope it does that should resolve my issue, thank you.
Do you think that the wall thickness in relation to the nozzle size has anything to do with it? My nozzle is .4mm hence it makes sense to do the wall thickness at .4 however I read ...
"Slicers typically will use 20% as the value of the extrusion width, this is due to an effect known as die swell. so for example, if you are using a 0.4mm nozzle the wall thickness, track width or extrusion width should be set to 0.48"
Does this sound correct to you? Once more thank you!
